The LEGEND VALVE 313-004 is a 3/4-inch flare x male iron pipe (MIP) coupling fitting designed for water service applications. This adapter connects a 3/4-inch flare end to a 3/4-inch male threaded pipe end, making it a common transition fitting in potable water and plumbing supply lines. Licensed plumbers and service technicians install this type of fitting when transitioning between flare tubing connections and threaded pipe systems. The T-4100 model designation indicates its place within the Legend Valve fitting product line.
This fitting is used in residential and light commercial water service installations where a flare-to-threaded male connection is required. Typical applications include supply line hookups, shutoff valve connections, and transition points between copper or soft tubing and threaded pipe assemblies. It is sold in quantities of 10 per carton and 60 per case, making it practical for both single-job use and stocking trade inventory.
Designed as an OEM-style flare x MIP adapter fitting for residential and light commercial water service plumbing systems where a 3/4-inch flare connection meets a 3/4-inch male threaded pipe connection.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before making any connections. Apply thread sealant or PTFE tape to the male threads before assembly. Do not overtighten flare fittings, as this can damage the seating surface and cause leaks.
