Parker 2F-C2L-1-BN-B Check Valve 1/8 Inch Fnpt Brass

Product Description

The PARKER 2F-C2L-1-BN-B is an in-line check valve designed to allow one-directional flow and prevent backflow in pressurized fluid and gas systems. Built with a brass body and nitrile rubber seals, this valve handles working pressures up to 3000 psi and opens at a crack pressure of 1.00 psi. The stainless steel spring ensures consistent performance across a wide range of media. This valve is sized for 1/8 inch pipe with female NPT connections on both ends, making it a compact, direct-install component. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers in both service and new-construction settings.

This check valve is suited for residential and light commercial applications where a low-profile in-line backflow prevention device is required. Common installation scenarios include compressed air lines, hydraulic circuits, refrigeration or pneumatic control tubing, and small-bore plumbing runs. Its 1/8 inch FNPT x FNPT configuration fits standard pipe thread fittings without adapters, making it easy to integrate into existing manifolds, control panels, or instrument lines. The high maximum working pressure of 3000 psi makes it appropriate for demanding industrial and fluid-power circuits as well.

Key Features

• In-line check valve prevents backflow and maintains system pressure integrity
• Brass body provides corrosion resistance suitable for water, air, and compatible hydraulic media
• Nitrile rubber seals offer good resistance to petroleum-based fluids and general-purpose gases
• Stainless steel spring delivers consistent crack pressure performance over service life
• Low crack pressure of 1.00 psi ensures the valve opens with minimal upstream pressure drop
• Maximum working pressure of 3000 psi supports high-pressure pneumatic and hydraulic applications

Compatibility

Designed as an OEM-style replacement or new-installation check valve for systems using 1/8 inch FNPT threaded connections operating up to 3000 psi with media compatible with brass and nitrile rubber seals.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the line completely before removing any existing valve or fitting. Apply thread sealant or PTFE tape to the male NPT threads mating to this valve per standard trade practice and applicable code requirements such as the IPC or IFGC. Verify flow direction before tightening, as check valves are directional and will not function correctly if installed in reverse.
