3/8" OD Solid Brass Compression Cap

Securely seal off unused water supply lines with this premium 3/8" Solid Brass Compression Cap. Providing a dependable permanent or temporary termination point, it is the perfect solution for bypassing appliances, capping lines during remodels, or closing open branches on a plumbing tee. It fits standard 3/8" male compression fittings, valves, or supply tubes, allowing you to easily isolate sections of your plumbing system without replacing entire shut-off valves.

Engineered from high-grade, lead-free brass, this heavy-duty cap offers exceptional structural integrity and long-term reliability. Its corrosion-resistant construction is built to withstand high water pressures and temperature fluctuations, ensuring an extended lifespan. 

Installation is quick and efficient for both DIYers and professionals. It creates a robust mechanical compression seal requiring no soldering, welding, or messy glues. Simply tighten the cap onto your existing male threads with a standard wrench for a secure fit.
