Parker 8A-C8L-1-SS Check Valve 1/2 in Compression Ss

Product Description

The PARKER 8A-C8L-1-SS is a stainless steel inline check valve rated for 1/2 inch pipe with compression x compression end connections. It is designed to allow one-directional fluid or gas flow and prevent backflow in high-pressure piping systems. Constructed with a stainless steel body and stainless steel spring, this valve carries a maximum working pressure of 6000 psi and a crack pressure of 1.00 psi. It is suited for demanding industrial, HVAC, plumbing, and instrumentation applications where corrosion resistance and pressure integrity are critical requirements.

This valve is installed inline in 1/2 inch pipe runs using compression fittings on both ends, making it compatible with tubing connections that do not require welding or threading. It is appropriate for use in hydraulic lines, compressed gas systems, instrumentation circuits, and fluid handling systems where backflow prevention is required. The compression x compression configuration allows for straightforward field installation in tight or confined piping arrangements encountered in both commercial and industrial settings.

Key Features

• Stainless steel body and spring provide excellent corrosion resistance in aggressive media environments
• Maximum working pressure of 6000 psi supports high-pressure hydraulic and gas service
• Low crack pressure of 1.00 psi allows the valve to open with minimal upstream pressure differential
• Compression x compression end connections enable tool-accessible installation without welding or threading
• Inline valve orientation keeps installation compact within existing pipe runs
• 1/2 inch pipe size fits standard tubing and instrumentation line sizes

Compatibility

Designed as an OEM-style inline check valve for 1/2 inch compression tubing systems operating up to 6000 psi in industrial, instrumentation, and fluid handling piping applications.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or instrumentation technician familiar with high-pressure compression fittings. Depressurize and isolate the line completely before removing any existing fittings or installing this valve. Verify flow direction markings on the valve body before making final connections, as reverse installation will block flow. Follow applicable codes such as ASME B31.3 or local piping codes for pressure system work.
