It's a WATTS valve
First one ordered was a dud. Had a slow leak. I have a PRV + expansion tank installed and set to 65PSI so wasn't a a result of my plumbing. Ordered a replacement and 2nd one is working fine. Apparently these are not tested when manufactured. This is not a Rheem part. Water heater manf do not make these parts but source them from other suppliers. But it is a Watts and repackaged by Protech. So is still a major brand name valve.

OEM Fit
Exact product replacement, does not leak like the 11-year old one replaced. Relatively easy installation during a larger effort to replace the magnesium anode rod. This part was as close to trivial as you can get. EDIT: If a new valve leaks, check your water pressure, as you may have a failed pressure reducing valve in the system. It’s a good idea to check line pressure at least twice a year anyway. It’s a very good idea to do that if you are in a hard water area.

Replaced a similar holder when the tensioner finally wore out. Love the tensioner as it gives the option for one hand usage. Very sturdy.
