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

Product Description

The PARKER 6Z-C6L-1-SS is an inline check valve designed to permit one-directional fluid flow while preventing backflow in pressurized piping systems. Built with a stainless steel body and stainless steel spring, this valve is rated at 6,000 WOG (Water, Oil, Gas), making it well suited for demanding industrial and mechanical applications. The compression x compression end connections allow for straightforward installation into 3/8 inch tubing runs without welding or threading. Licensed plumbers, pipefitters, and mechanical contractors typically specify this type of valve where corrosion resistance and high-pressure reliability are required.

This check valve is intended for inline installation in 3/8 inch compression-fitted piping systems. Its all-stainless construction makes it appropriate for corrosive media, high-purity fluid lines, hydraulic circuits, and similar service environments found in commercial and industrial facilities. The compression fittings on both ends make it compatible with standard 3/8 inch tubing commonly used in HVAC refrigerant circuits, pneumatic lines, and process piping.

Key Features

• Stainless steel body and spring construction for corrosion resistance in demanding service environments
• 6,000 WOG pressure rating for high-pressure fluid, oil, and gas applications
• Compression x compression end connections for tool-accessible, no-weld installation on 3/8 inch tubing
• Inline configuration allows installation anywhere along a straight tubing run
• Compact design suitable for tight installation spaces in mechanical systems

Compatibility

Designed as an OEM-style inline check valve for 3/8 inch compression-fitted piping systems across industrial, commercial, and mechanical applications where stainless steel construction and high WOG ratings are required.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and isolate the line completely before cutting into any existing piping. Compression fittings must be seated and tightened properly to achieve a leak-free seal; verify all connections with a pressure test before returning the system to service. Follow applicable codes including IPC and IFGC where relevant to the fluid or gas being conveyed.
