Watts JK-P-345-PEX-Z4 3/4 Pressure Reducing Valve, PEX

The Watts JK-P-345-PEX-Z4 3/4 is a genuine jumper kit for 3/4" JK-P-345-PEX-Z4 pressure reducing valves.

This 3/4" jumper kit with PEX end tailepiece and tubing is used in new construction as a temporary by-pass, prior to the actual installation of a water pressure reducing valve on potable water supply systems. The use of a temporary jumper permits testing of the building piping system for leaks and pressure loss and facilitates pipe flushing prior to the installation of the water pressure reducing valve. On unsecured jobsites, the jumper kit reduces loss from theft or vandalism.

• Plastic nipple
• PEX end tubing
• Pipe stiffener
