Ndl Industries W1279 Copper Fpt Adapter 1-5/8x1-1/2 C X Fpt

Product Description

The NDL INDUSTRIES W1279 is a copper female adapter designed to transition between a sweat (copper) connection and a female pipe thread (FPT) connection. It accepts a 1-5/8 inch copper tube on the sweat end and connects to a 1-1/2 inch FPT fitting on the threaded end. This type of adapter is a standard fitting used in plumbing and HVAC piping systems where copper tubing must terminate into a threaded joint. Licensed plumbers and pipefitters install this fitting during rough-in work, equipment connections, and system modifications.

This adapter is suited for residential and light commercial plumbing and hydronic systems where a copper sweat-to-female threaded transition is required. It is commonly installed at equipment connections, valve inlets, or manifold ports where copper pipe terminates into a threaded female port. The C x FPT configuration allows the installer to solder the copper tube end and thread a male-threaded component into the FPT side.

Key Features

• Copper construction for reliable soldered sweat connections
• 1-5/8 inch sweat (C) inlet transitions to 1-1/2 inch FPT outlet
• C x FPT configuration suits copper-to-threaded joint transitions
• Standard adapter geometry compatible with typical pipe layout and valve connections

Compatibility

Designed as an OEM-style copper fitting for use in plumbing and HVAC piping applications requiring a 1-5/8 inch sweat to 1-1/2 inch female pipe thread transition.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting or soldering. The sweat end requires proper flux application and soldering technique to achieve a leak-free joint. Do not apply thread sealant to the sweat end.
