Mcguire lf172 Closet Supply Kit Angle Stop 1/2 Sweat 3/8 Comp

Product Description

The MCGUIRE lf172 is a complete closet supply kit designed for toilet rough-in installations in residential and light commercial plumbing applications. The kit centers on a chrome plated brass angle stop valve with a 1/2 inch sweat (soldered) inlet and a 3/8 inch OD compression outlet. A full-turn brass stem and wheel handle give the technician straightforward shutoff control. The stop is paired with a 12 inch copper flexible riser and a steel deep bell flange, delivering everything needed to complete a single closet supply connection. The assembly is lead free and carries a cUPC listing, making it suitable for potable water service under current code requirements.

This kit is intended for angle stop applications at the wall supply point feeding a toilet tank. It is suited to residential new construction and remodel work where the rough-in supply is a 1/2 inch copper line requiring a sweat connection. Licensed plumbers and journeyman-level installers typically specify this kit when replacing an existing angle stop and supply line as a unit, or when finishing a new rough-in where all three components — stop, riser, and escutcheon flange — need to coordinate in finish and fit. The chrome plated finish integrates with standard chrome escutcheon and fixture trim commonly found in residential bathrooms.

Key Features

• Lead free construction meets current potable water regulations
• 1/2 inch sweat inlet with full-turn brass stem for reliable shutoff
• 3/8 inch OD compression outlet connects directly to standard toilet supply shank
• 12 inch copper flexible riser included — no separate supply line required
• Steel deep bell flange covers the wall supply penetration cleanly
• Wheel handle style for manual operation without tools
• cUPC listed to applicable standards

Compatibility

Designed as an OEM-style replacement or new-installation kit for residential closet (toilet) angle stop applications with a 1/2 inch copper sweat supply line and a 3/8 inch compression toilet fill valve shank.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and depressurize the line before beginning any work on the angle stop. The sweat inlet requires proper flux application, torch technique, and a clean, deburred copper pipe end — do not overheat the valve body. After soldering and before restoring water pressure, verify all compression fittings are snug and check for leaks at both the inlet and outlet connections.
