Pasco 33321 Hot Stem Assembly 333 Series

Product Description

The PASCO 33321 is a hot-side stem assembly designed as a direct replacement component for faucets in the PASCO 333 Series. Stem assemblies control hot water flow and shutoff within compression-style faucet bodies by threading into the valve seat and regulating water passage through the washer and packing. This part is installed by licensed plumbers and experienced service technicians performing faucet repair or rebuild work on residential and light commercial fixtures. Correct stem replacement restores proper shutoff function and eliminates dripping caused by worn internal components.

This stem assembly is suited for hot-side faucet repair applications where the original PASCO 333 Series stem has worn, cracked, or stripped threads. Typical install scenarios include leaking faucet repair, routine maintenance rebuilds, and fixture restoration where replacing the full faucet body is not practical or cost-effective. The hot designation indicates this stem is calibrated for the hot water supply side of the faucet and is not interchangeable with the cold-side stem in the same series.

Key Features

• Hot-side designation ensures correct thread pitch and stem geometry for the supply side of the valve
• Direct replacement fit for PASCO 333 Series faucet bodies
• Restores proper water shutoff and eliminates drip caused by worn stem components
• Designed for compression-style faucet repair without full fixture replacement

Compatibility

Designed as a hot-side OEM-style replacement stem for PASCO 333 Series faucets.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the water supply at the nearest isolation valve or main before disassembling the faucet body. Remove the existing stem carefully to avoid damaging the valve seat, and inspect the seat for wear before installing the replacement stem. Follow all applicable local plumbing codes, including IPC guidelines, for faucet repair and fixture service.
