Hi-Duty Flareless Tube Fittings| Parker

Parker's Hi-Duty flareless tube fittings are preassembled, with a sleeve machined onto the nut. This sleeve breaks away from the nut during assembly, creating a seal on the tubing. Hi-Duty fittings are rated to a higher pressure rating than compression fittings and will work with seamless steel tubing, copper, brass and thermoplastic tubing.
