Replacement insert for valves
January 1, 2008
Designed for use with existing P-series and VPS/3A valve bodies, clamps and gaskets, the Delta Swapp sanitary single-seat replacement insert features a metallic stop that ensures defined compression of the seat area and minimizes stress and load on seat seals. Consisting of a wear-resistant PTFE/elastomer shaft seal and shaft bearing, the insert has no gaps, crevices or O-rings to clean.
