Pressure Balance Cartridge

What is this?

This is a high-capacity replacement pressure balance cartridge designed for single-handle tub and shower valves. Measuring 3-1/4 inches in length, it serves as the primary internal component for regulating both water flow and temperature.

What does it do?

• Scald Protection: The integrated pressure-balancing mechanism protects users from sudden changes in water temperature caused by pressure fluctuations elsewhere in the plumbing system (such as a toilet flushing).

• Restores Smooth Operation: This cartridge replaces worn or mineral-clogged internal parts, restoring a smooth, easy rotation to the shower handle.

• Eliminates Leaks: It provides a fresh set of factory-standard seals to stop persistent drips from the showerhead or leaks from behind the decorative wall plate.

• Durable Construction: Built with high-grade internal components, it is engineered to withstand the friction and heat of daily use while resisting the corrosive effects of hard water.

Will it fit my needs?

This unit features a 20-point spline (the "teeth" where the handle attaches) and is approximately 3-1/4 inches long. It is a standard maintenance part for single-handle shower valves that utilize a rotating handle to control temperature. If your current shower handle is difficult to turn or the water temperature is inconsistent, this is the specific internal unit required for a professional-grade repair.
