Legris 7985 04 11 5/32" Tube x 1/8" MNPT Check Valve

SKU CH-PCQN-EBHV2 MPN 7985

Inline check valve allows flow in one direction with a 3.6 psi cracking pressure and nickel-plated brass body

  • TypeDrain Components
  • Inline check valve stops backflow in pneumatic lines
  • Nickel-plated brass body resists corrosion and wear
  • Push-to-connect 5/32" tube to 1/8" MNPT thread
  • Operates from -32 °F to 158 °F with nitrile seals
  • Opens at low 3.6 psi cracking pressure

Push-to-connect inline check valve

This nickel-plated brass and nylon check valve uses a push-to-connect tube end and a BSPT threaded end. It allows flow in one direction while preventing backflow in pneumatic circuits. The cracking pressure is 3.6 psi. It mounts horizontally or vertically.

Systems needing low-pressure pneumatic backflow

Suits automation lines, pneumatic tools and compressed-air piping where a compact inline valve is required. Not for hydraulic circuits, steam lines or applications above 158 °F. Buyers needing higher pressure ratings or different connection types should look elsewhere.

3.6 psi cracking pressure

This is the minimum upstream pressure needed to open the valve. If the system pressure drop must stay below this value, the valve will not operate correctly. Verify the circuit pressure before purchasing.

Questions about this item

How do I verify the 7985 04 11 check valve is working after installation?

Apply system pressure above 3.6 psi cracking pressure and confirm flow in the push-to-BSPT direction; no flow should occur in reverse.

What comes in the box and what must be purchased separately?

The valve body with nickel-plated brass and nylon construction is included; 5/32 in tubing and 1/8 in BSPT fittings are not supplied.

Which version of the Legris 7985 should I choose for my application?

Select the 7985 04 11 model when you need a 5/32 in tube by 1/8 in MNPT inline check valve with nitrile seals rated to 158 °F max temperature.
