Double-Wall®

Bimba Double-Wall® cylinders convert into six NFPA mounting styles and utilize easy to assemble "bolt on" mounting kits.  An epoxy coated aluminum tie-tube outer shell protects the inner 304 stainless steel body tube from harsh environments.  This design allows these cylinders to withstand dents and dings that would normally cause single wall cylinders to fail.

  • Bore sizes:  1-1/2", 2", 2-1/2", 3-1/4", 4"
  • Six NFPA rod end options
  • Aluminum alloy self aligning head
  • Hard chrome plated rod
  • Quick delivery of catalog models — off the shelf to 3 days!
  • Custom designed cylinders available to meet your exact specifications and requirements
