The LARSEN SUPPLY CO., INC. X-76P is a Union Gopher faucet seat designed for compression-style faucet repair. This small but critical component seals against the faucet washer to stop water flow when the handle is closed. A worn or pitted seat causes drips even after a washer replacement, making the seat itself the next logical service item. The X-76P measures 5/8 inch in diameter with an 18-thread-per-inch specification, making it a precise replacement for seats of that thread class. It is packaged individually and sold in quantities of 10 per package, making it practical for plumbers stocking a service van.
This faucet seat is suited for residential and light commercial compression faucet repairs. It is installed during routine faucet rebuilds when the existing seat is damaged, corroded, or worn beyond resurfacing. Plumbers typically encounter this repair in older two-handle faucets where compression valve assemblies are still in service. The 5/8 inch by 18-thread specification is a common dimension found in that style of fixture, and having the correct thread count on hand prevents a return trip.
Designed as an OEM-style replacement faucet seat for compression-style faucets requiring a 5/8 inch by 18-thread seat. Verify thread count and seat diameter against the existing fixture before installation.
A licensed plumber typically handles faucet seat replacement as part of a compression faucet rebuild. Shut off the water supply at the fixture stop valve or main shutoff before disassembly. A seat wrench with the correct hex or square drive is required to remove the old seat and thread in the replacement without damaging the faucet body. Do not overtighten the seat, as cracking the faucet body is possible with excessive force on older brass or pot-metal housings.
