1" Metal PEX Bend Support

1" PEX is very stiff. It is very difficult to bend the PEX to fit into these brackets, and if you succeed, the tabs on the bracket are not strong enough to hold the PEX. The tabs just bend and release the PEX. I tried both PEX-A and PEX-B and ran into similar problems.

I usually don't do reviews. But this part is absolutely garbage. The 3/4 and 1/2 work good. Seat diameter too small. Does not hold pex in bend shape. Does not fit around the Uponor pex pipe. Get the plastic Viega ones. Those work. Still hard to install, but they work.

This bend support is not strong enough to keep from deforming under the stress of 1" Pex-B tubing, even if pre-formed. It was not useful for its intended purpose.

These are the worst. The 1" pipe won't stay in. Works better on 3/4. To make it work I crimped the ends and made it work.

I bought 2 of these & several of the plastic ones. I broke two if the plastic ones. These worked well. They are a little flimsy but dud the job. I would get them again

I purchased several of these to do a heat install job. I was using an O2 barrier pex-B tubing that I purchase in straight lengths. I installed one on a piece of tubing and set it aside because I wasn't quite ready to install it. Moments later I heard a pop and heard the support bouncing on the concrete. These are not strong enough to work with a pipe that isn't curved to begin with. I had to return them because I will not use many of them from here on.

One part of this seal kit was changed in design and no wording of use this new design. Also the Grundfos instructions only showed pictures. These issues are from Grundfos. The price was high for what was supplies but Supply House had a fair price compared to other supplies of the same product. After installing the seal kit the problem was not the seal kit, instead the front housing had a crack or pin hole in it causing the leak. Lots of other people on the internet had the same issue.
