Compression Stem Assembly

What is this?

This is a professional-grade replacement compression stem unit designed specifically for the hot water (right-hand) side of manual faucets. Unlike modern ceramic cartridges, this unit utilizes a traditional mechanical compression design to regulate water flow.

What does it do?

• Reliable Flow Control: It uses a traditional rising stem mechanism that compresses a rubber washer against a brass seat to create a watertight seal.

• Durable Construction: Built with a heavy-duty brass body, this stem is engineered to handle the high temperatures of commercial and residential hot water lines without warping or degrading.

• Quarter-Turn Feel: Despite being a compression unit, it is designed for efficient operation, typically offering a smooth 90-degree to 180-degree turn to reach full flow.

• Maintains Water Safety: It is manufactured to meet lead-free standards, ensuring it is safe for use in potable water systems (drinking and cooking).

Will it fit my needs?

This stem is a common replacement for many widespread and centerset faucets used in both kitchen and bathroom applications. It features a specific spline count for handle attachment and is the standard solution for fixing a faucet that is leaking from the spout or has a "mushy" handle feel.
