Swagelok B-8C-1 Brass Poppet Check Valve is a fixed-pressure, inline check valve that prevents reverse flow in low-pressure lines. It uses 1/2 in. Swagelok tube fittings and has a cracking pressure of 1 psig (0.07 bar), making it suitable for protecting downstream instrumentation and components from backflow. The brass body and compatible Swagelok tubing connections provide reliable sealing in compact, inline installations.
