About this item
- Components: IWS-1960R PEX-a Expansion Tool Kit with 1/2 in., 3/4 in. and 1 in. expander heads, tool lubricant and a convenient carrying case.
- Purpose: Designed to make F1960 cold expansions. Solid, permanent, manufactured connections without the need for torches, glues, solder, flux or gauges can be expected by expanding Non-Barrier PEX Tubing and reinforcing ring to make a connection with an ASTM F1960 fitting.
- Features: Equipped with an Auto Rotation Adapter. Users can simply hold the tubing and tool in place while separating and closing the handles to expand the tubing. The Auto Rotation Adapter will automatically rotate to ensure the tubing is evenly expanded. Roration is not visible because it's triggered only when expansion head teeth is encircled with PEX-a tubing in real expansion situation and active handle is expanded to its full openning
- Secure Connection: Once the fitting is inserted into the expanded ring and pipe combination, the elastomeric properties of this PEX combination bring the expanded material back around the fitting to make a sealed, permanent and visually inspectable connection.
- Applications: Plumbing, fire safety, radiant heating and cooling systems. Ideal for residential, commercial and industrial projects.

IWS-1960R Auto Rotation Expansion Tool
- Kit includes convenient custom-molded carrying case, expander tool, three expander heads, grease and PEX tubing cutter.

- Includes everything needed to make 1/2 in. - 1 in. PEX-a connections.
- Steel construction for superior reliability and strength.
- Metal frame and gear mechanisms ensure the utmost durability.
- Go/no-go gauges are never required.
- Compatible with most cold expansion-style tools.

-
Is PEX Expansion better than Crimp?
PEX crimp equipment is a lot more affordable than the expansion kits. However, despite of form shortcomings, most plumbers prefer to work with expansion because installation is more efficient.
-
How many expansions are needed to complete expansion?
It's recommended to expand 1/2'' by 4 times, 3/4'' by 8 times and 1'' by 10 times. Note: Experience, technique and weather conditions may influence the actual number of expansions.
-
Why reviews say the tool is not auto rotation?
Auto rotation is triggered only when the expansion head is encircled by PEX-a tubing during expansion.

Customers find that the hose pipe fitting works well and is easy to use. They appreciate its value for money, saying it's an inexpensive alternative to electric PEX-A spreaders. However, some customers have issues with fit. There are mixed opinions on build quality, auto rotation, and leakage.
AI-generated from the text of customer reviews
Customers appreciate the tool's functionality. They say it works well, is of high quality, and requires a lot of force. Many customers find it useful for water flow over longer connections and small numbers of PEX fittings.

"I bought this over a year ago and it works great. I have used it many times...." Read more
"Solidly made, worked well. Maybe not yet best choice for everyday work, but excellent for an occasional job!" Read more
"...in the end though, I think this tool would work wonders for water flow over longer connections...." Read more
Customers are satisfied with the tool quality. They find it a good kit and worth the physical work. It's a nice alternative to expensive Milwaukee battery-powered tools and a great tool to have on hand.
"...Overall, great tool. Of course, some battery powered tool is easier to use, but the price is 3 times higher. p.s...." Read more
"...Maybe not yet best choice for everyday work, but excellent for an occasional job!" Read more
"This is a great tool for Plumbers, everyone should have one just in case you need to do some quick repairs. This makes those repairs go very quickly...." Read more
"I’m happy with this purchase. It is as good as the Wirsbo made tools I’ve used...." Read more
Customers appreciate the value for money of the hose pipe fitting. They find it tiring after a few uses, but worth the savings for smaller jobs and an inexpensive alternative to electric PEX-A spreaders.
"Great price for good quality. Manual expanding tool great for personal use. Buy a powered expander for routine use." Read more
"...This tool is far cheaper and I had high hopes for the auto-rotating head, but it does not seem to function as well as described...." Read more
"I bought this tool because it was one of the cheaper PEX-A tools that looked like it would get a single job done for me and I didn't care if it..." Read more
"...which was our case. Worth the $ if you have to make Pex A repairs or additions to Pex A piping...." Read more
Customers find the product easy to use. It's straightforward for fittings up to 1/2" in diameter. However, some customers mention battery-powered tools are easier to use, but the price is three times higher.
"...Overall, great tool. Of course, some battery powered tool is easier to use, but the price is 3 times higher. p.s...." Read more
"...I could not tell you how easy it is to work with this tool. I have had my new shower now for about a month and could not be happier." Read more
"...Just as easy to use just different tools needed. I have both and use the crimp on style more because of options available." Read more
"...All in all was pretty easy to use. No difficulty with 1/2” fittings. I had a few 3/4” and those were somewhat difficult...." Read more
Customers have different views on the tool's build quality. Some find it well-made and good for DIY projects, while others feel flimsy and not suitable for production work. The case may not be as advertised, and some customers experienced failure after making fewer than 10 fitting connections.
"...This makes those repairs go very quickly. Good quality and I definitely recommend them." Read more
"...Now that I've used it several times, I'm presently surprised at how well built it is, and I fully expect it to be the only one I ever have to..." Read more
"...See pics for the steps to make a joint. The tool is robust, works better than advertised, and makes excellent joints...." Read more
"...I have used it many times. One important note: It tends to over-expand the connections so they take a while to seal...." Read more
Customers have different experiences with the auto rotation feature of the hose pipe fitting. Some say it works well without being in a tube, while others mention it doesn't rotate automatically and you have to rotate the tool manually.
"Gotta rotate the pipe yourself but far better than paying $400 for an auto tool." Read more
"...It rotates as you clamp/ pump the product...." Read more
"...I returned this model because it did not spin as advertised. I will buy the less expensive model and save around 40%." Read more
"It expands the pex-a tubing perfectly. The auto rotation seems to work without it in a tube but not as consistently when you have it actually..." Read more
Customers have different experiences with leaks. Some report no leaks, while others say the rotation after expansion causes leaks.
"...My connection ended up leaking and I finally moved on to a sharkbite connector for that one area...." Read more
"...lmao! in the end, we did NOT have 1 leak. I am glad that project is over........." Read more
"...Purchased the expansion tool with autorotation and I got leaks on almost all of my joints and on the springs on the 3/4 fitting head broke in the..." Read more
"...Overall though, Wirsbo is a delight to use. Never had a leak, which is much more than I can say about soldering...." Read more
Customers find the fit of the hose pipe fitting to be tight and difficult to reach. They also mention that the carry case has an odd fit, making it hard to squeeze in certain positions. Some customers also say that the hand pump can be a little difficult to squeeze, so be prepared to use some muscle if you're doing 3/4 inch expansion.
"...Better to have a helper. 2. Some places were tight and hard to reach, so not a lot of leverage or space to expand the arms...." Read more
"...for me was that it is internaly lubed with black grease that never stops squeezing out and makes the inside of the PEX tubing dirty with non-potable..." Read more
"...Might not work in tight places and if you need to expand one inch pipe. It might not work...." Read more
"...It can be a real bear to squeeze in certain positions, so it can be a real workout. But for basic use at waist level or lower, it’s not a problem...." Read more

- Reviewed in the United States on February 12, 2025Pattern Name: Auto Rotation ExpanderVerified PurchaseSolidly made, worked well. Maybe not yet best choice for everyday work, but excellent for an occasional job!
- Reviewed in the United States on January 13, 2025Pattern Name: Auto Rotation ExpanderVerified PurchaseThe tool works great for a small number of pex fittings. Expanding 1" pex with this tool took about every ounce of strength I have. After using this I invested in a battery-powered tool to make my life easier.
- Reviewed in the United States on January 6, 2025Pattern Name: 1/2'', 3/4'', 1'' ExpanderVerified PurchaseI bought this over a year ago and it works great. I have used it many times.
One important note: It tends to over-expand the connections so they take a while to seal. I have had more than a few 1/2 connections that leaked at first and didn't fully seal until more than an hour later. Once they seal, however, the connections are fine.
- Reviewed in the United States on August 31, 2022Pattern Name: Auto Rotation ExpanderVerified PurchaseI did about 100 expansions in two days. It's a good workout. Two things:
1. For 1/2'' fitting you have about 3 sec, 3/4'' - 5 sec to properly insert the fitting. Have to be quick and agile. Better to have a helper.
2. Some places were tight and hard to reach, so not a lot of leverage or space to expand the arms. Had to assemble some legs on the desk and then connect the whole ensemble.
Overall, great tool. Of course, some battery powered tool is easier to use, but the price is 3 times higher.
p.s. Previously I asked the question, if the tool has auto-rotation or not. It does, it's just hard to observe, but it does.
- Reviewed in the United States on January 4, 2025Pattern Name: Auto Rotation ExpanderVerified PurchaseEverything you need to fasten expansion pex. All wrapped in nice portable Hardcase
- Reviewed in the United States on August 14, 2023Pattern Name: 3/8'', 1/2'', 3/4'', 1'' ExpanderVerified PurchaseThis is a great tool for Plumbers, everyone should have one just in case you need to do some quick repairs. This makes those repairs go very quickly. Good quality and I definitely recommend them.
- Reviewed in the United States on January 9, 2025Pattern Name: Auto Rotation ExpanderVerified PurchaseI would have preferred that electric hand tool for the job, but the prices on those are expensive for a home D.I.Y person.
This tool is far cheaper and I had high hopes for the auto-rotating head, but it does not seem to function as well as described.
Never having used one of these I may not have enough grease on the head, or possibly too much grease on the head. Still have some more pex to run, so I will try more/less as I move forward to see if it helps the rotation or not.
- Reviewed in the United States on June 2, 2024Pattern Name: 3/8'', 1/2'', 3/4'', 1'' ExpanderVerified PurchaseI used this to redo my parents pipes under their kitchen sink. Needless to say, I think sweating some copper might have been an easier way for the space that I was working in. But I decided to give this a try. I went through a lot of the plastic collar rings, but that was just me trying to get everything in there in a manner that it didn't look like crap. overall, this tool gives you a work out! we used all brass fittings which proved to be worth it as I cut and redid a lot of those fittings till I like the design. lmao! in the end, we did NOT have 1 leak. I am glad that project is over......
in the end though, I think this tool would work wonders for water flow over longer connections.
I liked it and I'm happy with the way things turned out.
