Brass Poly-Tite Fitting, Nut, 61PN (PARKER NUT 3/8 61PN6)

PARKER NUT 3/8 61PN6|Parker’s poly-tite fittings are compact, and pre-assembled to speed any installation. An exclusive acetal copolymer sleeve holds the plastic tubing right where it belongs, even when the system pressure exceeds the tubing burst point. The sleeves have superior resilience to resist creeping and stress, and can even protect from UV rays. The nuts will rotate around the sleeve as it tightens to prevent twisting and weakening of the plastic tubing. These fittings can be used with Parflex or other high-quality thermoplastic tubing or pneumatic instrumentation circuits, lubricant and coolant lines and applications with other gases and liquids.
