3/8" x 1/2" MPT Push-Fit Adapter – Tool-Free Transition Fitting for Copper, CPVC, and PEX Systems

The 3/8" push-fit x 1/2" male pipe thread (MPT) adapter is a brass transition fitting designed for quick, mechanical connections between CTS tubing (copper, CPVC, or PEX) and standard threaded components. Engineered for use in potable water systems, it enables tool-free installation without soldering, crimping, or gluing. The integrated stainless steel grab ring and EPDM O-ring ensure reliable sealing under pressure.

Installation Notes

Cut CTS pipe squarely and deburr before insertion. Mark the proper insertion depth (typically 0.95" for 3/8" CTS) and push the pipe into the fitting until seated fully. No tools are required. Compatible with copper (Type K, L, M), CPVC (SDR-11), and PEX (ASTM F876/877) tubing. Verify local code acceptance and pressure test all connections per project specifications.

Application Scope

This push-fit adapter is commonly installed in:

• Residential and light commercial potable water distribution systems
• Retrofitting copper or CPVC to threaded brass or iron fittings
• Service valve connections and fixture stub-outs

Material and Use Consideration

Push-to-connect fittings are suitable for concealed and exposed installations when installed according to manufacturer guidelines and local plumbing codes. Not recommended for use in continuous high-temperature closed-loop hydronic systems or steam applications.
