Tapco P864 Posi Pak Short Stem Right Hand Hot

Product Description

The TAPCO P864 is a short-stem faucet cartridge replacement designed for right-hand hot water service. This stem fits into the hot-side valve seat of a faucet assembly, controlling water flow and temperature at the source. Plumbers and service technicians install this type of stem when an existing hot-side stem is worn, stripped, or leaking past the seat. The Posi Pak design refers to the cartridge-style stem format, which is engineered for straightforward drop-in replacement without special tooling in most standard applications.

This stem is intended for use in residential and light commercial faucet repair applications where the original hot-side stem has failed or degraded. The right-hand orientation indicates the threading direction of the stem, which is a critical detail when sourcing a replacement. Confirm the stem orientation and thread pitch of the existing valve before installation to ensure proper fit and seal.

Key Features

• Short-stem profile for compact faucet valve bodies
• Right-hand hot configuration for correct threading direction and hot-side service
• Posi Pak cartridge-style format supports direct drop-in replacement in compatible valves
• Designed as a service replacement to restore proper shut-off and flow control

Compatibility

Designed as an OEM-style replacement stem for right-hand hot faucet valve assemblies requiring a short-stem Posi Pak cartridge. Confirm stem length, thread pitch, and spline count against the original part before ordering.

Installation Notes

Installation is typically performed by a licensed plumber or experienced service technician. Shut off the water supply at the nearest isolation valve or main before removing the existing stem. Standard faucet stem tools and seat wrenches are commonly used for this service. Always inspect the valve seat for wear or damage before installing the new stem, as a damaged seat will cause the replacement to leak prematurely.
