Seamless Coiled CNG Tubing

PAC Stainless is your stocking source for stainless steel tubing for use in compressed natural gas (CNG) stations. CNG XP™ Tubing, manufactured by HandyTube Corporation, is a premium long-length coil that has been specifically engineered with CNG filling stations in mind. This application demands a tubing product that can provide maximum flow over long, leak free lengths of a highly compressed small molecule gas, while minimizing potential leak points. This product is fully heat- and lot-traceable and meets ASTM A269/A213 certification standards. Available in T316/L (2.5% min. Mo.) Stainless Steel.










Reduce Costs

CNG XP™ Tubing is a truly seamless product, free from longitudinal or orbital welds.

  • Continuous coil lengths allow for significant reductions in labor costs and installation time
  • Eliminate the need for welding multiple 20' length sticks together
  • Eliminate potential leak points and the need for testing welds
