Brass Compression Stop Valve Cap

These brass compression caps seal 5/16 inch OD tubing with a 1/2-24UNS thread. The pack contains ten pieces for HVAC, plumbing, fuel, water, air or gas lines. Hexagon design allows easy installation and removal with a wrench. Corrosion-resistant brass construction suits indoor and outdoor use.

Replaces worn or missing flare caps

Upgrade when existing caps leak, corrode or strip during service. The precise thread restores a reliable seal on air conditioners, water heaters, washing machines or garden lines. Worth the change whenever a fitting shows seepage or thread damage. Ten-piece pack covers multiple points in one order.

Check thread size and tube OD before ordering

Verify the connection uses 1/2-24UNS threads and 5/16 inch outside diameter tubing. Do not over-tighten during installation to avoid fitting damage. Ensure the hex width of 14.88mm matches your wrench. Confirm the application pressure and media are compatible with brass.
