Larsen Supply X-126P Faucet Seat 5/8 in X 20 Thread 10 Pack

Product Description

The LARSEN SUPPLY CO., INC. X-126P is a replacement faucet seat machined from Arrowhead Brass, sold in a bag of 10 units. The seat measures 5/8 inch in diameter with a 20-thread-per-inch specification, making it a direct-replacement component for standard faucet valve bodies. Faucet seats are the sealing surface against which the stem washer or cartridge seats to stop flow. A worn or pitted seat causes dripping that a new washer alone will not fix. Plumbers and pipefitters install these during faucet rebuilds to restore a clean, leak-free seating surface without replacing the entire valve body.

This faucet seat is suited for residential and light commercial plumbing repair work. It fits applications where a 5/8-inch, 20-thread faucet seat is required, including compression-style faucet valve bodies commonly found in older construction and retrofit plumbing situations. The 10-unit bagged pack is practical for service technicians who stock repair parts on a truck or in a shop inventory for routine faucet rebuild calls.

Key Features

Compatibility

Designed as an OEM-style replacement faucet seat for compression-style valve bodies requiring a 5/8-inch, 20-thread seat. Confirm thread count and seat diameter against the existing valve body before installation.

Installation Notes

Faucet seat replacement is performed by licensed plumbers or experienced service technicians. Shut off the water supply and relieve line pressure before disassembling the faucet. Use a seat wrench sized to the internal drive of the seat to remove the old seat and thread in the replacement. Work to IPC standards for potable water fittings and ensure the new seat is fully seated and snug before reassembling the valve stem.
