Brasscraft SCD1311D Faucet Seat 1/2 Inch 20 Thread

Product Description

The BRASSCRAFT SCD1311D is a polypropylene faucet seat designed as a replacement component in compression-style faucet valve assemblies. Faucet seats serve as the sealing surface against which the stem washer presses to stop water flow. This seat features a 1/2-inch diameter with 20 threads per inch, matching the thread specification of the 970-510 seat standard. Plumbers and service technicians install this part during faucet rebuilds when the original seat is worn, pitted, or cannot be dressed with a seat grinder. The polypropylene construction resists corrosion in both hot and cold water supply lines.

This faucet seat is suited for residential and light commercial plumbing applications where a 1/2-inch by 20-thread replacement seat is required. It is commonly installed during compression faucet repair on bathroom and kitchen fixtures. Technicians replacing stems, washers, or O-rings often inspect and replace the seat at the same time to ensure a proper shutoff. The polypropylene material makes it appropriate for installations where a non-metallic seat is specified or preferred.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the water supply and relieve line pressure before disassembling the faucet. Use a seat wrench sized to the seat socket to remove the old seat and thread in the replacement without cross-threading. Work should conform to applicable local plumbing codes and IPC guidelines.
