Sioux Chief 642PX2 Pex 90 Degree Elbow 1/2 in Polymer 25pk

Product Description

The SIOUX CHIEF 642PX2 is a 1/2 inch polymer 90 degree elbow fitting designed for use in PEX tubing systems. This insert-style elbow provides a directional change in PEX water supply lines, redirecting flow at a right angle without requiring heat or soldering. Made from a polymer construction, the fitting is compatible with standard PEX crimp and clamp connection methods. Each bag contains 25 fittings, making it a practical choice for new construction roughins or repipe projects where multiple directional changes are required across a system.

This fitting is used in residential and light commercial plumbing applications where PEX tubing is the distribution method of choice. Typical install scenarios include potable water supply lines, hydronic heating systems, and radiant floor distribution manifolds. The 1/2 inch size is the most common size in residential hot and cold supply branch lines. The 25-count bag quantity suits plumbers stocking a service vehicle or staging materials for a full roughin.

Installation Notes

Installation is performed by licensed plumbers following IPC and local plumbing code requirements. Shut off the water supply and depressurize the line before cutting into any existing system.
