Full Product Description

Parker's Hi-Duty fittings are preassembled with the sleeve machined onto the nut. During assembly the sleeve breaks away from the nut and seals on the tubing. This unique design creates tight joints that withstand pressures of most commonly used types of tubing including seamless steel tubing, copper, brass and thermoplastic tubing. This design also provides a vibration dampener which enables joints to stand up under moderate vibration.
