Parker's Prestolok composite pneumatic push-to-connect fittings reduce assembly time by eliminating the use of a sleeve and tightening of a nut required in compression style fittings. Simply push the tubing into the fitting until it bottoms. These quick connect pneumatic fittings are also easy to disassemble: just press the release button, hold against the body and pull tubing from the fitting. A D-seal in the Prestolok PLP composite air fitting provides a positive seal on the O.D. of the tubing in both static and dynamic positions. The D-seal deforms during insertion of the tubing lowering the insertion force without compromising the sealing feature. A thread sealant is applied to all male threads eliminating the possibility of system contamination from PTFE tape. All components in Prestolok PLP composite are silicone free. All Prestolok PLP composite push in fittings are 100% leak tested and date coded to guarantee quality and traceability. For use with the following Parker Parflex Division tubing.
