Zurn (Wilkins) NR3XL Model is Residential Pressure Regulator. Designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure. The integral strainer makes this device most suitable for residential water systems that require frequent cleaning of sediment and debris. The direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion. The balance piston design enables the regulator to react in a smooth and responsive manner to changes in system flow demand, while at the same time, providing protection from inlet pressure changes. Provides highest level of corrosion resistance.

I only wish it had direct PEX connections. I had to use two pipe adapters on each end to get to my 1 inch PEX. The only leaks in my PEX system were the pipe adapters threaded connections. Seems very well built.

Drawing for this item shows a Gasket, Tailpiece, Union Nut on both sides of this valve, however there is only one supplied in the box.Is this correct and if so, how do I get another Gasket Tailpiece and Union Nut?Thank you, Tracie

This particular models has only one union connection. As you can see from the product image, the valve has internal threads (1" FNPT) on both sides also, which means that to facilitate removal, you would need to disconnect the union and then unscrew the whole unit from the threaded connection on the other side. A union on the other side is really not required, since one union is sufficient to remove the unit (for repair, replacement, etc.) without having to cut and re-connect the piping.
