Metal support bracket used for PEX A

[Dielectricunion]

I recently saw a rough-in and noticed some of the stub outs on the water heater were supported by expanding the pex after it was pushed through a metal bracket. It felt solid and it was a support method I'd never thought of. With the tight fit and differing expansion rates, I was wondering if this would be regarded bad practice, or is it a common acceptable way?

I think it will leak over time. Who knows how long, but eventually I think that pipe will wear thru and leak.

That is Absolutely Wrong! Right idea but wrong implementation. The problem with using a copper holdrite bracket meant for copper pipe, is that it will cut through the PEXover time. The surfaces are too rough.

While PEX and Copper are the same size on the exterior normally.. the expanded portion shown next to the elbow is larger.. so its likely wedged into the bracket already.

This is the style that we use on our projects. They work for all CTS / copper tube sized pipe.
