Legend Valve 303-127 Brass Compression Pipe Coupling

Product Description

The LEGEND VALVE 303-127 is a brass compression pipe coupling designed to join 1-1/4 inch pipe to 1-1/2 inch copper tube without soldering or threading. Rated at 125 psi WOG (Water, Oil, Gas), it handles a maximum working temperature of 180 degrees F. The all-brass construction resists corrosion and provides reliable sealing under sustained pressure. This fitting is used in residential and light commercial plumbing applications where a mechanical, tool-assisted connection is required. Licensed plumbers and pipefitters install this type of coupling during new construction, renovation, or repair work on water distribution and low-pressure gas supply lines.

This coupling is suited for applications requiring a transition between standard pipe and copper tube sizing. It is appropriate for use in water supply systems, low-pressure gas lines, and similar fluid-handling systems that operate within its 125 psi and 180 degrees F rating. The compression design eliminates the need for an open flame, making it a practical choice in retrofit or confined-space installations where soldering is not feasible.

Key Features

• 125 psi WOG pressure rating for water, oil, and gas service
• Maximum working temperature of 180 degrees F
• Brass construction for corrosion resistance and long service life
• Compression-style connection — no soldering or threading required
• Connects 1-1/4 inch pipe to 1-1/2 inch copper tube in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation compression coupling for 1-1/4 inch pipe and 1-1/2 inch copper tube plumbing systems rated up to 125 psi WOG.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and relieve system pressure before disassembling any existing fittings. Ensure tube ends are cut square and deburred before seating in the compression fitting. Do not over-tighten the compression nut, as excess force can deform the ferrule and cause leaks.
