  • Oversized wear band on the rear of the piston achieves longer life than competitive cylinders.
  • High-strength aluminum alloy tube provides a smooth corrosion-free sealing surface and excellent abrasion resistance.
  • High-strength, ductile steel piston rod has a ground, polished, and hard chrome-plated surface providing maximum bushing and seal life.
  • Tie rods are 100,000 psi minimum-yield steel for maximum holding power. Tie rod threads are rolled for strength and engagement.
  • Enhanced port design enables increased flow rate and faster breakaway.
  • Bushing retainer permits cartridge removal without disassembly.
