The ASHLAND WATER GROUP MA75NL is a 3/4-inch yellow brass male adapter designed to connect plastic pipe to threaded fittings in residential and light commercial plumbing systems. Constructed from lead-free yellow brass, this adapter features a barbed end for secure attachment to plastic tubing and a male threaded end for connection to standard threaded fittings. The lead-free construction meets current federal and state lead-free compliance requirements for potable water systems. Licensed plumbers and pipefitters install this fitting as part of transition connections where plastic supply lines meet metal threaded ports.
This adapter is suited for use in potable water supply lines, irrigation connections, and general plumbing applications where plastic pipe must transition to a threaded metal fitting. The barbed end grips the inner wall of compatible plastic pipe, providing a reliable mechanical connection without soldering. It is commonly used in residential water supply rough-in, fixture connections, and outdoor irrigation systems where plastic tubing is the primary pipe material.
Designed as an OEM-style replacement or new-installation fitting for 3/4-inch plastic pipe plumbing systems requiring a male threaded transition to a barbed connection point in potable water applications.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before installing or removing any fittings. Hand-tighten the threaded connection first, then use an appropriate wrench to finish seating without overtightening brass threads. Ensure the plastic pipe is fully seated over the barb before securing with a clamp or crimp ring as required by the specific pipe type.
