Legend Valve 105-101 Inline Check Valve 1/4 in Fnpt Brass

Product Description

The LEGEND VALVE 105-101 is a 1/4 inch inline check valve designed to allow fluid flow in one direction while preventing backflow in plumbing and fluid-handling systems. The body is constructed from brass, offering solid corrosion resistance in both water and light-fluid service applications. Both end connections are female NPT (FNPT x FNPT), conforming to ANSI/ASME B1.20.1 threading standards and ANSI/ASME B16.18 cast copper alloy fittings specifications. This valve is sized for 1/4 inch pipe and weighs approximately 0.45 pounds, making it a compact, durable component suited for professional installation in residential and light commercial piping systems.

This check valve is appropriate for inline installation in plumbing supply lines, HVAC condensate or fluid circuits, and similar low-diameter piping runs where backflow prevention is required. The 1/4 inch FNPT x FNPT configuration allows it to thread directly into standard pipe fittings without adapters. Licensed plumbers and pipefitters working on residential or light commercial systems will find this valve fits common service scenarios where a compact, threaded brass check valve is specified.

Key Features

• Brass body construction provides corrosion resistance for water and compatible fluid service
• FNPT x FNPT end connections on both inlet and outlet for direct threaded installation
• 1/4 inch pipe size suits small-diameter inline backflow prevention applications
• Meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards for dimensional and threading compliance
• Compact and lightweight at approximately 0.45 pounds

Compatibility

Designed as an OEM-style inline check valve replacement for 1/4 inch FNPT threaded pipe connections in residential and light commercial plumbing and fluid-handling systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and ANSI/ASME standards. Shut off the water supply and relieve system pressure completely before removing any existing valve or fitting. Apply thread sealant tape or compound rated for the service fluid to the male threads being engaged with the FNPT connections. Verify flow direction is correct before returning the system to service, as check valves are directional components.
