Legris 7995 12 17 Inline Check Valve 3/8 in Tube Od Bspt

Product Description

The LEGRIS 7995 12 17 is an inline check valve designed for compressed air and pneumatic plumbing systems. It allows flow in one direction and prevents backflow automatically without manual actuation. The body is molded from nylon and is finished in black. It connects via a 12 mm tube outside diameter fitting on one end and a 3/8 inch male BSPT threaded port on the other. The valve is rated for service up to 158 degrees F, making it suitable for a wide range of industrial and commercial pneumatic installations. Plumbers, pipefitters, and pneumatic system technicians are the primary installers of this type of component.

This check valve is applied in inline pneumatic or compressed air lines where backflow prevention is required. The tube OD by male BSPT end configuration suits systems that transition between push-to-connect or compression tube fittings and British Standard Pipe Taper threaded ports. It is commonly installed in industrial automation, compressed air distribution, and light commercial pneumatic control circuits. The nylon body keeps weight low and resists corrosion in typical pneumatic service environments.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or pneumatic systems technician. Depressurize and lock out the air supply before removing any existing fittings or installing this valve. Ensure the BSPT threads are wrapped with PTFE thread seal tape or an appropriate thread sealant before assembly to prevent leakage. Verify flow direction arrow or internal orientation before finalizing the installation to ensure the check valve functions correctly in the intended flow path.
