Legend Valve 113-311 Manual Ball Valve 1/4 in Mnpt X Fnpt

Product Description

The LEGEND VALVE 113-311 is a manual ball valve designed for 1/4-inch pipe connections in fluid control applications. It features a stainless steel body and stainless steel handle, providing corrosion resistance in demanding service environments. The valve connects via male NPT (MNPT) on one end and female NPT (FNPT) on the other, allowing straightforward inline installation without additional adapters. Quarter-turn operation gives the technician fast, positive shutoff. This valve is typically installed by licensed plumbers, HVAC technicians, or pipefitters working on water, compressed air, or compatible fluid systems where a compact, durable manual shutoff is required.

This ball valve is suited for residential and light commercial plumbing, hydronic heating, compressed air lines, and similar piping systems where a 1/4-inch threaded shutoff is needed. The MNPT x FNPT end configuration allows it to thread directly into existing pipework or equipment ports without additional fittings. Its all-stainless construction makes it a practical choice in corrosive or wet environments where brass valves may not be appropriate.

Key Features

• Stainless steel body for corrosion resistance in wet and chemical-exposure environments
• Stainless steel handle for durability and long service life
• 1/4-inch MNPT x FNPT threaded ends for direct inline installation
• Quarter-turn manual operation provides fast, positive shutoff
• Compact form factor suited to tight installations on small-diameter lines

Compatibility

Designed as an OEM-style replacement or new-installation manual ball valve for 1/4-inch NPT-threaded piping systems in plumbing, HVAC, and compressed air applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off system pressure and drain the line before removing any existing valve or installing this unit. Apply thread sealant tape or pipe compound to the male threads before assembly and tighten to hand-tight plus the appropriate number of turns for NPT fittings — do not over-torque stainless steel threads. Verify there are no leaks at operating pressure before returning the system to service.
