The wiper rings is a double-acting scraper with two O-rings functioned as elastic energizer to preload the PTFE compound ring. Its profile seal ring consists of a sealing lip and a wiper edge. The double O-ring design can improve rod sealing performance under short-stroke and high-frequency motion that is common application in fork-lift trucks, injection molding machines, compression molding press, and agriculture equipment. A small bore hole for relieving pressure is recommended for some combined seals that lack of sufficient pump-back capability.
