Larsen Supply Co X-58P Faucet Seat 20 Thread

Product Description

The Larsen Supply Co X-58P is a replacement faucet seat designed for American Standard faucet applications. This faucet seat measures 0.5 inches in diameter by 0.4375 inches in height with a 20-thread count, providing a precise fit for maintaining a proper watertight seal within the faucet body. Plumbers and plumbing service technicians install this component during faucet rebuilds and repair service calls where the original seat has worn, pitted, or corroded beyond resurfacing. The part ships in a bagged format in a package quantity of 10, making it practical for stocking in a service van or shop inventory.

This faucet seat is suited for residential and light commercial faucet repair work involving American Standard fixtures. It is used in compression-style faucet assemblies where the seat interfaces with the washer to control flow and stop drip conditions. Typical scenarios include older lavatory and sink faucets that require seat replacement rather than full fixture replacement, allowing the technician to restore function and eliminate leaks at the stem base.

Installation Notes

Faucet seat replacement is performed by a licensed plumber or qualified plumbing technician. Shut off the water supply at the fixture stop valve or at the main before disassembly. Use a seat wrench of the correct drive size to remove the old seat and thread in the replacement, taking care not to cross-thread or overtighten. Work should conform to applicable local plumbing codes and manufacturer service guidelines.
