Description
The Larsen Supply Co. X-16P is a Union Gopher faucet seat designed for use in faucet repair and reseating applications. This small but critical component creates the sealing surface that a faucet washer or stem presses against to stop water flow. When a faucet seat becomes pitted, scored, or corroded, replacing it restores a proper shut-off and eliminates drips. Measuring 33/64 inches in diameter with an 18-inch thread specification, the X-16P is sold in a bagged package of 10 units, making it practical for plumbers who service multiple fixtures on a single job.
Faucet seats are used in compression-style faucets found throughout residential and light commercial plumbing. The X-16P is appropriate for standard faucet seat replacement work on sinks, lavatories, and similar fixtures where the original seat is removable. Licensed plumbers and experienced service technicians typically carry a selection of faucet seats to handle common seat sizes encountered in the field.

Installation Notes
Faucet seat replacement is performed by licensed plumbers or qualified service technicians. Shut off the water supply to the fixture and relieve line pressure before disassembling the faucet. Use a seat wrench of the appropriate size to remove the old seat and drive the replacement into place without cross-threading. Verify the new seat is fully seated and flush before reassembling the stem and testing for leaks.
