Kingston 215A Horizontal In-Line Brass Check Valve — FNPT x FNPT, 250 PSI
The Kingston 215A is a spring-loaded brass check valve designed for in-line installation in horizontal compressed-air and gas lines. It allows free flow in one direction and seats automatically to prevent reverse flow, protecting compressors, dryers, and downstream equipment from backflow and pressure loss.
Both ports are female NPT (FNPT x FNPT) for straightforward in-line piping. A precision-machined brass body, 25% glass-filled PTFE disc, and stainless steel spring deliver reliable, repeatable sealing in lubricated and non-lubricated service. The 3/8" and 1/2" sizes include a plugged 1/8" bleeder port.
