The LEGEND VALVE FITTING, INC. 312-004SS is a 3/4-inch MIP x insert adapter designed for use in plumbing systems where a male iron pipe threaded connection must transition to an insert-style fitting. This adapter provides a reliable mechanical connection between threaded pipe and insert-compatible tubing or components. It is a single-unit fitting intended for installation by licensed plumbers or experienced trade professionals working on residential or light commercial water distribution systems.
This adapter is suited for applications requiring a threaded-to-insert transition at 3/4-inch pipe size. Typical installation scenarios include potable water supply lines, hydronic distribution piping, and general plumbing retrofit work where existing threaded connections need to interface with insert-style tubing runs. The single-unit selling format makes it practical for targeted repairs and spot replacements.
Designed as an OEM-style replacement or direct-install fitting for 3/4-inch MIP x insert plumbing applications in residential and light commercial water distribution systems.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off the water supply and depressurize the line before beginning work. Apply thread sealant tape or pipe dope to the MIP threads before engagement. Do not overtighten the threaded connection, as this can damage mating fittings or distort the insert end.
