Description
The LARSEN SUPPLY CO. S-953-3 is a replacement shower stem designed to fit American Standard faucet valves using the 5363 H broach configuration. This stem controls hot and cold water flow in shower valve assemblies, functioning as the internal cartridge-style stem that interfaces with the faucet handle and seat to regulate water delivery. It is a direct OEM-style replacement part suited for service work on residential shower faucet valves. Plumbers and plumbing service technicians install this stem when a worn or damaged original stem causes dripping, hard handle operation, or failure to shut off fully. The part ships carded and is sold as a single unit.
This shower stem is intended for use in residential shower valve service applications where the American Standard 5363 broach pattern is required. The H broach designation indicates the specific spline or broach profile on the stem that must match the handle fitting. Technicians replacing leaking or worn stems in tub-shower or shower-only valve bodies will find this a direct drop-in replacement where the original American Standard 5363 H broach stem was installed. It handles both hot and cold positions, making it a versatile single-part solution for full valve restoration.

- Direct OEM-style replacement reduces callback risk on valve service calls

Compatibility

Installation Notes
Installation should be performed by a licensed plumber or qualified plumbing technician. Shut off the water supply to the shower valve and relieve line pressure before removing the old stem.
