The all stainless steel construction of the Prestolok PLS fittings with
FKM seals offer excellent resistance to aggressive environments
and fluids. The nutriment grade materials and USDA NSF H1 grease
conforming to FDA and 1934/2004 standards permits permanent
contact with food. The smooth surface design of the PLS fitting is
aimed at reducing retention zones for safe and easy cleaning. The
Prestolok PLS fittings are suitable for applications in markets such as
chemical, food, packaging and medical. All items in the PLS range are
silicone free.
