Ashland Water Group MA50NL 1/2 Inch Brass Male Adapter

Product Description

The ASHLAND WATER GROUP MA50NL is a 1/2-inch yellow brass male adapter designed to connect plastic pipe to threaded fittings in residential and light commercial plumbing systems. The barbed end grips the inside diameter of compatible plastic pipe securely, while the male threaded end engages standard threaded fittings or valves. Constructed from yellow brass, this adapter meets lead-free compliance requirements, making it suitable for potable water applications. Licensed plumbers and pipe fitters install this type of fitting during new construction, remodel work, and repair jobs where a transition from plastic pipe to a threaded metal connection is required.

This adapter is suited for use in cold and hot water supply lines where plastic pipe terminates at a threaded port. Typical applications include residential water distribution, irrigation system connections, and light commercial plumbing assemblies. The lead-free construction makes it appropriate for drinking water systems subject to state and federal lead-free compliance laws. The 1/2-inch size is the most common nominal pipe size in residential supply lines, making this fitting a high-frequency replacement and new-install component for plumbing contractors.

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/2-inch plastic pipe plumbing systems requiring a transition to a male threaded connection in residential and light commercial applications.

Installation Notes

Installation is typically performed by a licensed plumber. Shut off the water supply and depressurize the line before cutting or disconnecting any pipe. Apply appropriate thread sealant or PTFE tape to the male threads before engaging the threaded port. Do not overtighten the threaded connection, and ensure the barbed end is fully seated into the plastic pipe before securing with a clamp or fitting as required by local code.
