Ndl Industries w1131 Copper Male Adapter 5/8x1/2 C X Mpt

Product Description

The NDL INDUSTRIES w1131 is a copper male adapter designed to connect copper tubing to threaded pipe fittings in plumbing and mechanical systems. It features a C x MPT (sweat by male pipe thread) configuration, with a 5/8-inch copper sweat end and a 1/2-inch male pipe thread (MPT) outlet. This adapter is a standard transition fitting used wherever a copper line must terminate into a threaded connection. Licensed plumbers and mechanical contractors install this type of fitting during new construction, remodel work, and repair service on potable water and hydronic systems.

This fitting is suited for residential and light commercial plumbing applications where a sweat copper line must transition to a male-threaded connection point. Typical installations include supply line terminations, fixture rough-ins, and branch connections at valves or manifolds. The 5/8-inch sweat end accepts standard 5/8-inch OD copper tubing, and the 1/2-inch MPT end threads into a female-threaded fitting, valve, or port. It is sold in a box quantity of 25 units, making it practical for contractors stocking job boxes or completing multi-fixture rough-ins.

Compatibility

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before soldering. The sweat end requires proper flux application and lead-free solder per potable water standards. Apply thread sealant or PTFE tape to the MPT threads before making up the threaded joint.
