Larsen Supply SB-23 Shower Seat 21/32 in X 18 Thread

Product Description

The Larsen Supply Co SB-23 is a shower seat replacement fitting designed for Price Pfister shower valves. This small but critical component seals the shower valve seat area, preventing leaks and maintaining proper water flow control within the valve body. Measuring 21/32 inches in diameter with an 18 thread count, it provides a precise fit for compatible valve configurations. Each card includes 2 seats, making it practical for back-to-back service calls or a single repair with a spare. Plumbers and service technicians keep these on hand for routine shower valve rebuilds.

This shower seat is used in residential bathroom shower valve repair applications. When a shower valve develops a drip or fails to shut off cleanly, worn or damaged valve seats are a common cause. The SB-23 is suited for shower valve seat replacement work on Price Pfister fixtures. Its 21/32 inch by 18 thread specification matches the original seat geometry, allowing a direct drop-in replacement without modification during a standard valve service.
