Features / Benefits :
  • Available in Material SS316L.
  • Zero tolerance / clearance system – No requirement of cutting or flexing the Tubing to insert or remove Fittings, Valves or other Components for installations and repeat maintenance
  • Unlimited remakes – ORFS Fittings can be disassembled and reassembled many times by simply replacing the ‘O’ Ring and tightened its recommended torque.
  • Assembly Adaptability – Soft seal Fittings (ORFS) adjust to irregularities in the Fitting Face or Sleeve. So during assembly with proper techniques and handling, the Tube Fitting is forgiving the assembly variations.
