No maintenance required!

• Ideal for high-purity, low pressure
• No metal components — inert flow path
• No back flow leakage with back pressure of 0 to 100 psi
• 1/4-28 UNF threaded connections

Unlike spring-actuated check valves that may restrict or impede the flow path, this in-line check valve features a smooth flow path that minimizes shear and turbulence.
