The carboxilated nitrile with Teflon® compound rod seal is self-lubricating and durable. The rounded lip design ensures proper sealing and long Knife Gate life.
The standard rod wiper construction is a highly durable polyurethane.
High strength steel (100,000 psi minimum yield) piston rod has a ground, polished, and chrome plated surface. This surface provides maximum life for both the rod bushing and the seals.
The bushing retainer allows cartridge removal (cylinder repair) without complete disassembly.
The tie rods are 100,000 psi minimum yield steel for maximum holding power. The threads are roll formed for superior strength and engagement.
The piston seal is a carboxilated nitrile with Teflon® compound making it self-lubricating. The "T" seal with back-up ring construction prevents rolling and seals at all pressures.
