Swagelok SS-4C-VCR-5 is a stainless steel poppet check valve with a 1/4 in Swagelok VCR face-seal connection, designed for inline, one-way flow in gas and liquid lines. It is a fixed-pressure (non-adjustable) check valve rated at a cracking pressure of 5 PSIG, using a stainless-steel poppet and VCR seal to provide a tight, leak-tight seal when paired with Swagelok VCR fittings. The compact inline design supports standard 1/4 in tubing, making it suitable for backflow protection in precision fluid-handling systems.
