Larsen Supply Co. S-734-3 Shower Stem Sterling 5221

Product Description

The Larsen Supply Co. S-734-3 is a replacement shower stem designed to restore proper valve function in older Sterling shower faucet assemblies. Built to fit the Sterling 5221 valve body, this stem features a D broach interface and is available in both hot and cold configurations. The old-style design matches the original OEM geometry, making it a reliable drop-in solution for service calls on aging plumbing fixtures. Licensed plumbers and experienced service technicians install this part when a worn or damaged stem causes dripping, cross-flow, or failure to shut off in a shower valve.

This shower stem is intended for residential and light commercial plumbing applications where Sterling 5221 series shower valves are installed. It is suited to retrofit and repair scenarios where original-style stems are no longer readily available through standard supply channels. The D broach seat interface is a key fitment detail — verify the broach pattern on the existing handle before ordering. Both hot-side and cold-side positions are covered by this part number.

Installation Notes

Shut off the water supply to the shower valve before beginning stem replacement. A licensed plumber should perform this repair in jurisdictions that require permitted plumbing work. Use appropriate stem socket tools to remove and seat the stem without damaging the valve body threads. Verify stem length, broach pattern, and seat compatibility before installation to confirm proper fit and shutoff performance.
