Cylinder Tube: Hard anodized aluminum tube, RC 60 on I.D. This provides superior wear resistance for maximum seal life.

Head and End Caps: Machined from solid 6061-T6 aluminum allow extrusion for long life and corrosion resistance.

Piston: Machined from solid 6061-T6 aluminum alloy.

Piston Rod: C1050 steel alloy 100,000 psi minimum yield, ground and polished with a hard chrome finished 68-70 RC. Four NFPA rod ends are offered. Optional stainless steel is available.

Piston Seals: Dynamic O-ring, nitrile seals that reduce friction for extended life. Optional seals include Viton and ELF (extra low friction).

Rod Bearing: Low friction nylon rod bearing that provides long life under normal side loading. The bearing is easily replaceable.

Rod Seal: Pressure energized, high quality nitrile lip-type rod seal.

Rod Wiper: Polyurethane rod wiper that protects the rod seal from foreign particles for maximum life.
