Polytop Sets have found widespread popularity due to their unique set configurations and high sealing efficiency. A Garlock Polytop CHEVRON® set utilizes both squeeze and multiple lip type seals. Used in a set configuration, these two proven designs combine to provide maximum sealing performance.

Garlock Polytop Seal Sets provide excellent sealing efficiency. Unlike typical V-sets, Polytop Sets need no axial preload or adjustment after startup, virtually eliminating the fear of catastrophic failure. Compounded from the highest quality urethane, the GARTHANE® 9220 U-Seal is strong and abrasion-resistant. In the Polytop configuration, it replaces the traditional top adapter used with vee sets and provides an additional sealing lip. The fabric and rubber composition of Garlock 432 CHEVRON® provides a strong, yet flexible sealing system that dampens any pressure surges.
