Legend Valve 105-102 Inline Check Valve 3/8 in Fnpt Brass

Product Description

The LEGEND VALVE 105-102 is a brass inline check valve designed to permit one-directional flow and prevent backflow in piping systems. The valve uses female NPT connections on both ends, sized at 3/8 inch, making it straightforward to thread into existing lines without adapters. The brass body offers corrosion resistance suitable for water, light hydronic, and general plumbing service. This part is installed by licensed plumbers and pipefitters during new construction, retrofit, and repair work where backflow prevention is required at a compact inline location.

This check valve is suited for residential and light commercial plumbing applications. Typical installations include supply lines, branch connections, and equipment protection circuits where reverse flow could cause system damage or contamination. The FNPT x FNPT end configuration allows direct threaded installation into standard pipe fittings. It conforms to ANSI/ASME B1.20.1 for pipe threads and ANSI/ASME B16.18 for cast copper alloy fittings, confirming dimensional and material compliance for code-required installations.

Key Features

• Brass body construction provides corrosion resistance for plumbing and hydronic service
• FNPT x FNPT end connections thread directly into standard NPT fittings
• 3/8 inch pipe size fits common branch and supply line applications
• Meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards
• Inline valve orientation simplifies installation in tight or inline piping runs

Compatibility

Designed as an OEM-style replacement or new-installation inline check valve for 3/8 inch FNPT threaded piping systems in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before removing any existing fittings or installing this valve. Apply thread sealant or PTFE tape to male threads before making up the connection. Verify flow-direction orientation before completing the installation, as check valves are not bidirectional.
