3/8" Tube Check Valve

The Legris 7985 60 14 is a nickel-plated brass and nylon inline check valve designed for 3/8 inch tube to 1/4 inch BSPT connections. It suits plumbing installers and maintenance teams who need a reliable single-flow device for fluid or air lines. The push-to-connect inlet and threaded outlet simplify assembly in tight service panels.

Push-to-Connect Inline Fit

A push connection on the tube side removes the need for flare tools or compression nuts, while the 1/4 inch BSPT male thread mates with standard port fittings. The compact inline body leaves clearance for adjacent components and can be mounted horizontally or vertically without re-piping. Nitrile seals handle the specified temperature range from -32 °F to 158 °F.

Sustained Pressure Behaviour

The valve opens at a 3.6 psi cracking pressure and maintains full flow once unseated, preventing flutter during steady-state operation. Nickel-plated brass construction resists corrosion over long service intervals, and the nitrile seat holds seal integrity through repeated thermal cycles. California Proposition 65 notices apply to chemicals present in the materials.

Questions about this item

What is the maximum temperature the Legris 7985 check valve can handle before the seals degrade?

The valve is rated for a maximum operating temperature of 158 degrees Fahrenheit; exceeding this limit can compromise the nitrile seals over time.

How much heat does the valve generate during continuous flow operation?

The valve itself produces no heat; fluid temperature is determined by the supply, and the nitrile seals are rated up to 158 degrees Fahrenheit.

What tubing size and thread type must the existing system have to connect this valve?

The inlet requires 3/8 inch push-to-connect tubing and the outlet needs a 1/4 inch BSPT male thread for installation.
