Ndl Industries W1230 Copper Female Adapter 5/8x3/4 C X Fpt

Product Description

The NDL INDUSTRIES W1230 is a copper female adapter designed to connect a 5/8-inch copper tube to a 3/4-inch female pipe thread (FPT) fitting. The connection type is C x FPT, meaning one end is a sweat (solder) connection and the other accepts a threaded pipe. This adapter is a standard plumbing component used to transition between copper tubing and threaded pipe systems. Plumbers and HVAC technicians install this fitting during new construction and retrofit work where copper lines must terminate at a threaded port or valve.

This adapter is suited for residential and light commercial plumbing and HVAC applications where a 5/8-inch copper line needs to transition to a 3/4-inch FPT connection. Typical installations include supply lines, branch connections, and equipment hookups that require a threaded interface on one end. The fitting ships in a box quantity of 25, making it practical for contractors and service techs who need multiples on hand for ongoing work.

Installation Notes

Installation of this fitting is performed by licensed plumbers or HVAC technicians. Shut off the water supply and relieve system pressure before soldering. The sweat end requires proper flux application and a clean, deburred copper tube end before torch soldering. Thread the FPT side onto a male-threaded fitting using an appropriate thread sealant or PTFE tape in accordance with local plumbing codes.
