Swagelok B-6C-VI-1 Brass Inline Poppet Check Valve

Swagelok B-6C-VI-1 Brass Inline Poppet Check Valve is a brass-bodied inline check valve for 6 mm Swagelok Tube Fittings with a fixed-pressure cracking point of 1 psig (0.07 bar). This poppet-type valve allows forward flow while preventing reverse flow in low-pressure fluid or gas lines, making it suitable for instrumentation, pneumatic, and other compact installations where a reliable one-way flow path is required. The 6 mm tube connections facilitate straightforward integration into 6 mm tubing networks, and the brass body is designed for typical lab and process environments where corrosion resistance is beneficial. O-rings used in brass valves are commonly Buna N, which supports a durable seal across standard operating pressures.
