Designed for fast installation, this PARKER Poly-Tite female connector features a body, nut, and sleeve pre-assembled and ready to install. The fitting is designed for use with thermoplastic tubing and it comes with a black acetal copolymer sleeve that resists ultraviolet rays and has excellent dimensional stability. The Poly-Tite nut rotates around the sleeve as it tightens to prevent twisting and weakening of the plastic tubing. Can be assembled and disassembled again and again for added flexibility. Suitable for pneumatic and liquid use in car wash, machine tool, packaging, and printing applications.
