Parker 2M-C2L-1-SS Inline Check Valve 1/8 in Mnpt Ss

Product Description

The PARKER 2M-C2L-1-SS is a stainless steel inline check valve designed to allow one-directional flow and prevent backflow in pressurized fluid or gas systems. Built for high-pressure service, it is rated to 3000 psi maximum working pressure with a crack pressure of 1.00 psi, making it suitable for demanding industrial, HVAC, and fluid-handling applications. Both the valve body and internal spring are constructed from stainless steel, providing corrosion resistance in harsh or wet environments. It connects via 1/8 inch male NPT (MNPT) fittings on both ends. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this component.

This check valve is suited for use in compressed air lines, hydraulic circuits, refrigeration systems, and other pressurized piping installations where backflow prevention is required. The 1/8 inch pipe size makes it appropriate for smaller-diameter lines in both residential and light commercial applications. Its all-stainless construction supports use in corrosive fluid service, high-humidity environments, and systems requiring sanitary or chemical-resistant materials.

Key Features

• Maximum working pressure of 3000 psi for high-pressure service
• Low crack pressure of 1.00 psi allows flow initiation with minimal system pressure
• Stainless steel body and spring for corrosion resistance and long service life
• MNPT x MNPT end connections for straightforward threaded pipe installation
• Compact 1/8 inch pipe size fits tight plumbing and instrumentation configurations

Compatibility

Designed as an OEM-style inline check valve for 1/8 inch MNPT threaded piping systems in industrial, HVAC, and fluid-handling applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable codes such as the IPC or IFGC. Depressurize and isolate the system completely before removing any existing fittings or installing this valve. Apply appropriate thread sealant to the MNPT connections and verify flow-direction orientation before pressurizing the line. Do not exceed the rated working pressure of 3000 psi during operation or pressure testing.
