Ndl Industries W1263 Copper Female Adapter 1-1/8x1 C X Fpt

Product Description

The NDL INDUSTRIES W1263 is a copper female adapter fitting designed to transition from a copper sweat (C) connection to a female pipe thread (FPT) connection. The fitting accepts a 1-1/8 inch copper tube on the sweat end and connects to a 1 inch female pipe thread on the threaded end. It is used in residential and commercial plumbing and HVAC hydronic piping systems wherever a copper line must terminate into a threaded port or valve. Licensed plumbers and HVAC technicians install this type of adapter when connecting copper distribution lines to threaded equipment connections, manifolds, or shutoff valves.

This adapter is suited for use in potable water, hydronic heating, and refrigeration piping applications where a C x FPT transition is required. The 1-1/8 inch sweat by 1 inch FPT size is common in larger residential and light commercial systems, including hydronic boiler piping, chilled water distribution, and copper main service lines. It is sold in a box quantity of 25 units, making it practical for contractors completing multi-connection installations or stocking service vehicles.

Key Features

• C x FPT connection type allows direct transition from copper sweat to female threaded pipe
• 1-1/8 inch sweat inlet by 1 inch FPT outlet sizing
• Copper construction for durability and compatibility with standard copper piping systems
• Sold in a box quantity of 25 for contractor use
• Standard adapter geometry compatible with common soldering and threading practices

Compatibility

Designed as an OEM-style copper sweat-to-FPT adapter for use with standard 1-1/8 inch OD copper tubing and 1 inch female NPT threaded connections in plumbing and HVAC piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before soldering. Clean and flux both the copper tube end and the fitting socket thoroughly before applying heat. Do not apply thread sealant to the copper sweat end — sealant or tape is used only on the male threaded fitting that engages the FPT port.
