Access Valves, Tees, Caps & Cores

Access valves, access tees, valve cores and valve caps for refrigerant service ports. Connection styles across the range include flare, SAE, MPT, sweat-or-braze, ODS and spigot, with 1/4 in. by far the most common size. Most of the range is brass, with copper, stainless, nickel-plated brass and neoprene-sealed caps also stocked.

Also here: access valve extensions and a valve core depressor. Caps are worth more attention than they usually get — the cap is the second seal on a service port, and a missing or cross-threaded one is a slow leak nobody finds until the next cooling season. Brands include TRADEPRO, DiversiTech, Novent, C&D Valve, CPS, JB and NAVAC.
