Parker Prestolok PLP nickel-plated brass 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. To disassemble, press the release button, hold against the body and pull tubing from the fitting. A thread sealant is applied to all male threads eliminating the possibility of system contamination from PTFE tape.
Composite push-to-connect fittings provide a simple way of connecting tubes to a fitting. Parker Prestolok composite fittings reduce assembly time by eliminating the use of a sleeve and tightening of a nut. All Prestolok PLP composite fittings are 100% leak tested and date coded to guarantee quality and traceability.
Parker's Prestolok PLM fittings have a high phosphorous, FDA compliant, electroless nickel plating which is resistant to water, harsh detergents and other aggressive fluids. Prestolok PLM fittings are fitted with a FKM O-ring protected by a washer and can be used with all liquid and gaseous fluids compatible with these components. Prestolok PLM fittings reduce assembly time by eliminating the use of a sleeve and tightening of a nut required in compression style fittings.
Fittings that come in contact with food must be corrosion resistant, non-toxic, non-absorbent and capable of being washed down and disinfected. Parker's Prestolok PLS Stainless Steel fittings have a 316L stainless steel body and washer and a 303L stainless steel collet. The Prestolok PLS fitting uses nutriment grade materials and USDA NSF H1 grease conforming to FDA standards, permitting permanent contact with food. Prestolok PLS has a hygienic design aimed at reducing retention zones for safe and easy cleaning.
