Having a compact check valve design allows us to do clever things. Our plain tube check valves are designed to be used with compression fittings, such as Swagelok and Parker, and eliminate the need for multiple connectors and fittings. Simply use the plain tube check valve within the compression fitting and no extra parts are needed. Needless to say, these check valves are perfectly suited for high working pressures.

Our plain tube check valves come in various sizes and materials. The standard models, available to buy online, are 1/4", 4mm (5/32") and our 1/8" check valve is the smallest spring assisted valve in the world. Standard materials are 316 stainless steel or PEEK, but we can manufacture in many other materials depending on your requirements. We also stock some check valves in Hastelloy material.
