The TAPCO P865 is a Posi-Pak short stem valve component configured for left-hand cold applications. This part is a replacement stem assembly designed to restore proper valve function in plumbing supply systems. The short stem form factor suits confined installation spaces, and the left-hand cold designation indicates its orientation and service side for accurate installation in paired hot and cold valve setups. Licensed plumbers and experienced service technicians are the typical installers of this component.
The P865 is suited for residential and light commercial plumbing applications where Posi-Pak style valve cartridges or stem assemblies are used. It is appropriate for sink, lavatory, or similar fixture valve repairs requiring a short stem, left-hand cold replacement. Install only in the cold-side valve position as indicated by the left-hand cold designation.
Designed as an OEM-style replacement stem for Posi-Pak style valve assemblies requiring a short stem left-hand cold configuration in residential or light commercial plumbing fixtures.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply completely and relieve line pressure before disassembling the valve body. Confirm the cold-side left-hand orientation matches the existing valve configuration before installing. Avoid over-tightening the stem assembly, as this can damage the valve seat or packing.
