Legend Valve 303-126 Brass Compression Pipe Coupling

Product Description

The LEGEND VALVE 303-126 is a brass compression pipe coupling designed to join 1-inch pipe to 1-1/4-inch copper tube without soldering or threading. It uses a compression-style connection that creates a reliable, leak-resistant seal rated at 125 psi WOG (water, oil, gas). The maximum working temperature is 180 degrees F. Plumbers and pipefitters install this fitting in residential and light commercial plumbing systems where a mechanical, tool-free joint is preferred or where open flame is not an option.

This coupling is suited for repair and new-installation work on copper tube supply lines in potable water, hydronic, and light-service piping applications. The brass construction resists corrosion in both hot and cold water service. It is a single-piece fitting sold individually, making it a practical choice for service calls where only one connection point needs to be addressed.

Key Features

• Brass construction for corrosion resistance in water and gas service
• Compression-style connection — no soldering, threading, or special tools required
• 125 psi WOG pressure rating for reliable service in typical plumbing applications
• Rated to 180 degrees F maximum working temperature
• Accepts 1-inch pipe and 1-1/4-inch copper tube for transition or repair connections

Compatibility

Designed as an OEM-style compression coupling for 1-inch pipe and 1-1/4-inch copper tube plumbing installations in residential and light commercial systems.

Installation Notes

This fitting is installed by licensed plumbers following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before disassembly or fitting installation. Ensure tube ends are cut square, deburred, and clean before inserting into the compression fitting. Do not overtighten the compression nut, as excess torque can deform the ferrule and compromise the seal.
