Sioux Chief 647WG32 Pex Fnpt Reducing Adapter 1/2 X 3/4 in

Product Description

The SIOUX CHIEF 647WG32 is a PEX-to-female NPT reducing adapter designed to transition between a 3/4-inch female NPT threaded fitting and a 1/2-inch PEX tubing connection. This fitting is used in potable water and hydronic piping systems where a reduction in line size is needed at a threaded port. It is installed by licensed plumbers and pipefitters during new construction, remodel, or repair work. The adapter provides a secure mechanical connection between PEX tubing and standard NPT-threaded components such as valves, manifolds, and fixtures.

This reducing adapter is suited for residential and light commercial plumbing applications where PEX tubing terminates at a threaded connection point. Common install scenarios include connecting 1/2-inch PEX supply lines to 3/4-inch threaded valve bodies, manifold ports, or shutoff valves. It is appropriate for both hot and cold water distribution lines within standard PEX plumbing systems.
