  • Competitive interchangeability with NFPA Aluminum cylinders.
  • File-hard, high-strength aluminum alloy lobe tube provides a smooth, corrosion-free, abrasion-resistant sealing surface - offering excellent performance in wash-down applications
  • Larger wear band and unique rod seal/wiper combination achieve longer cylinder life than competitive cylinders
  • Head and cap are machined from solid aluminum bar and anodized for corrosion resistance. A recess at the piston mating surface creates greater piston area exposed to air for a faster breakaway
  • Removable close-grain, graphite-filled, cast iron bushing offers the best bearing surface for the hard chrome-plated piston rod. The extra-long bushing offers excellent load bearing characteristics
  • Floating cushion design gives the fastest stroke reversal possible by providing instantaneous full flow to piston
