Parker 2M-C2L-1-BN-B Inline Check Valve 1/8 in Mnpt Brass

Product Description

The PARKER 2M-C2L-1-BN-B is a brass inline check valve designed to allow one-directional fluid or gas flow while preventing backflow in pressurized piping systems. It features 1/8 inch male NPT connections on both ends and is rated for a maximum working pressure of 3000 psi. The valve opens at a crack pressure of 1.00 psi and relies on a stainless steel spring to maintain reliable sealing performance. A nitrile rubber seal provides chemical resistance suitable for a range of media. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers of this component.

This check valve is suited for use in compact inline applications where space is limited and a 1/8 inch MNPT port is required. Common installations include pneumatic control lines, hydraulic circuits, compressed air systems, and instrumentation piping. Its brass body construction makes it appropriate for use with water, air, oil, and many other compatible media at elevated pressures. The small pipe size and male NPT threading on both ends allow straightforward installation into standard 1/8 inch female NPT fittings without adapters.

Key Features

• Brass body construction for durability and corrosion resistance in fluid and pneumatic service
• 1/8 inch MNPT x MNPT end connections for direct inline installation
• 3000 psi maximum working pressure rating for high-pressure system use
• 1.00 psi crack pressure allows the valve to open under minimal upstream pressure differential
• Stainless steel spring provides consistent return force and long service life
• Nitrile rubber seal material offers resistance to oils, fuels, and common system fluids

Compatibility

Designed as an OEM-style replacement or new-installation inline check valve for 1/8 inch female NPT ported systems operating up to 3000 psi with nitrile-compatible media.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified maintenance technician. Depressurize and isolate the system completely before removing any existing valve or fitting. Apply thread sealant or PTFE tape to the male NPT threads in accordance with applicable plumbing or piping codes. Verify flow direction markings on the valve body before final make-up to ensure correct orientation in the line.
