Parker 6A-C6L-1-SS Check Valve 3/8 in Compression Ss

Product Description

The PARKER 6A-C6L-1-SS is a stainless steel inline check valve designed to allow fluid or gas flow in one direction while preventing backflow. It features compression-by-compression end connections sized for 3/8 inch pipe and is rated for a maximum working pressure of 6000 psi, making it well suited for high-pressure hydraulic, pneumatic, and instrumentation systems. The stainless steel body and spring construction provide corrosion resistance in demanding service environments. A crack pressure of 1.00 psi ensures the valve opens readily under minimal differential pressure. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers of this valve.

This check valve is intended for inline installation in high-pressure fluid and gas systems where backflow prevention is required. Common applications include hydraulic control lines, instrumentation tubing, chemical process lines, and compressed gas distribution where stainless steel wetted materials are specified for corrosion or contamination reasons. The compression fitting connections allow tool-assisted installation into tubing runs without soldering or threading, streamlining assembly in panel or rack-mounted systems.

Key Features

• Stainless steel body and spring construction for corrosion resistance in aggressive media
• 6000 psi maximum working pressure rating for high-pressure hydraulic and instrumentation service
• 1.00 psi crack pressure for low-differential-pressure actuation
• Compression x Compression end connections sized for 3/8 inch tubing
• Inline valve orientation for straightforward in-line installation in tubing runs

Compatibility

Designed as an OEM-style inline check valve for high-pressure hydraulic, pneumatic, and instrumentation tubing systems using 3/8 inch compression fittings.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician. Depressurize and isolate the system completely before removing or installing any check valve. Compression fittings require proper ferrule seating using appropriate tube wrenches — do not overtighten. Verify that flow direction marked on the valve body matches the intended system flow direction before pressurizing the line.
