Toilet Supply Kit Components

This three-piece toilet supply kit from Kingston Brass contains every part required for the water flow process of a standard bathroom toilet. The set includes a single lever handle stop valve, a flat head supply line, and a low profile flange. All components are constructed from high-quality brass with a tarnish-resistant finish designed for long-lasting performance. The kit is available in multiple finishes to match existing home decor.

Installation and Common Issues

The kit uses compression connections at 58 OD and 38 OD sizes, which are tightened by hand and then with a wrench to create a watertight seal without soldering. The low profile flange fits a 12 pipe with a 58 ID, so verifying the existing pipe diameter before starting prevents fitment problems. Over-tightening the compression nuts can damage the brass ferrules and cause leaks, while debris on the pipe surface will prevent a proper seal. The flat head supply line measures 20 inches in length and must align cleanly with the valve and tank inlet.

Critical Sizing Specification

The stop valve features a 58 OD compression inlet and a 38 OD compression outlet, and the flange is sized for a 12 pipe with a 58 ID. These exact dimensions determine whether the kit matches the existing plumbing rough-in. If the supply pipe or valve connections differ from these measurements, the components will not seal correctly and a different kit is required.
