Single-Handle Pressure Balance Cartridge

$86.91

This is a high-capacity replacement pressure balance cartridge designed for single-handle tub and shower valves. Measuring 5-5/8 inches in length, it is a specialized internal component responsible for regulating both the flow and the temperature of the water.

What does it do?

  • Scald Prevention: It features an internal pressure-balancing mechanism that compensates for fluctuations in water supply pressure. This ensures that if a toilet is flushed or an appliance starts elsewhere in the building, the shower temperature remains stable and safe.

  • Leak Resolution: Replacing this unit is the primary fix for a showerhead that drips while the handle is in the "off" position or for water leaking from behind the decorative wall plate.

  • Restores Handle Precision: Over time, mineral deposits can make shower handles difficult to turn. This assembly provides a fresh, lubricated internal system that restores smooth, effortless rotation.

  • Heavy-Duty Build: Constructed from high-impact engineered polymers and corrosion-resistant brass components, it is designed for long-term reliability in both residential and commercial settings.

Will it fit my needs?

This cartridge is specifically identified by its 38-point spline (the "teeth" on the end of the stem where the handle attaches) and its 5-5/8 inch total length. It is used in various high-flow shower valves that require a longer-than-standard stem to reach through deep wall installations or specific trim styles.

What comes in the box?

  • Pressure Balance Cartridge Assembly

  • Integrated O-rings and Sealing Gaskets

The Pressure Balance Cartridge is a specialized repair component designed to restore safe temperature control and drip-free operation to your shower valve.
