Integrate seamlessly from a threaded port to a hose barb connection while safeguarding against backflows by installing a threaded check valve. All check valves feature a 1/8” NPT(M) thread for an easy, leak-free connection to manifolds, sensors, and instruments. Polypropylene body and silicone diaphragm construction offers high purity and exceptional chemical resistance.

The polypropylene body meets USP Plastic Class VI and FDA FDA 21 CFR 177.1520(c) 1.1a requirements, making these check valves ideal for pharmaceutical, food, and beverage applications. The silicone diaphragm opens at 0.5 psi and closes at 1.9 psi ensuring unidirectional flow. A free-floating, disk-based silicone diaphragm allows installation in any position. Single-barb design accepts flexible tubing.

Please note that the maximum operating temperature information is intended as a general guideline only; application testing is recommended, as specific chemical environments and pressures will influence these values.
