Pneumatic Push-To-Connect Check Valve 5/16 In OD X 5/16 In OD One-Way Valve Pack Of 2, Nickel Plated Brass Body With NBR Seals For Leak Free Air And Vacuum, Cracking Pressure 0.4 MPa

Pack of 2 5/16 in Push-To-Connect Check Valves
✔️ Nickel-plated brass body with NBR seals, 0.4 MPa cracking pressure

These push-to-connect check valves are designed for low-pressure air and vacuum lines, commonly used in pneumatic circuits, automation, and small equipment. They prevent backflow and protect vacuum lines by allowing one-way air flow.

✅ Working pressure: 0-150 psi (0-1.2 MPa) / 0-990 kPa
✅ Cracking pressure: 0.4 MPa (≈58 psi); negative pressure to -750 mmHg (-100 kPa)
✅ Material: nickel-plated brass body with NBR seals for leak-free connections
✅ Tubing: PU/PA/PE/PVC; 32-160 °F (0-70 °C); 5/16 in OD ports (≈7.94 mm)

💡 What is a pneumatic push-to-connect check valve used for in low-pressure air lines?

Handy for maintaining vacuum integrity and preventing backflow in small automation setups.

- Protects vacuum lines by preventing backflow - Easy to install with push-to-connect ends - Handy for low-pressure air and vacuum applications
