Moen 100743 Valve Body Replacement for Bathroom Faucets – Brass 3/8

Description

Product Overview

The Moen 100743 Valve Body is engineered as a precise, durable replacement component for bathroom sink faucets. Crafted from solid brass, this valve body offers superior corrosion resistance and a robust feel that stands up to daily use. Its 3/8 inch NPT (National Pipe Tapered) threaded connection aligns perfectly with standard faucet installations, ensuring a leak‑free seal that maintains consistent water pressure. The unfinished metal finish provides flexibility for any finishing touches you may prefer, while the compact dimensions (9.5 x 5 x 1.5 inches) allow it to fit seamlessly within most faucet housings.

Designed for both DIY enthusiasts and professional plumbers, the valve body integrates effortlessly into existing plumbing systems. The threaded design eliminates the need for specialized tools, and the brass material tolerates high temperatures and harsh water conditions without degrading. With a one‑year limited warranty from Moen, you can trust the longevity and reliability of this essential plumbing part.

Usage

This valve body is ideal for repairing or upgrading bathroom sink faucets that exhibit leaks, reduced flow, or worn‑out internal components. Whether you are restoring a classic Moen faucet or updating an older model, the 3/8 inch threaded size matches the majority of Moen’s widespread faucet lines, including those that use the Hydrolock Type installation system. Homeowners can replace a faulty valve body in a single afternoon, avoiding the expense and disruption of a full faucet replacement. The part is also suitable for commercial settings such as hotels, offices, and public restrooms where reliable faucet performance is essential.

Installation requires basic plumbing knowledge: shut off the water supply, disconnect the old valve, apply thread sealant to the new valve’s threads, and secure it in place. Once installed, re‑connect the faucet and test for proper operation. The valve body’s design ensures smooth water flow, reducing turbulence and noise, which contributes to a quieter bathroom environment.
