Prestolok PLM All Metal
Push-to-Connect Fittings
PLM push-to-connect forged fittings are nickel-plated and have an
FKM seal making them suitable for use with liquids and gaseous fluids
compatible with these components. PLM fittings are plated with a
high phosphorus FDA nickel-plate allowing these fittings to be used in
applications where exposure to aggressive environments is present.
The high phosphorus FDA nickel-plate is resistant to water, harsh
detergents and other aggressive fluids and environments resulting in
a superior chemical, corrosion and abrasive resistant push-to-connect
fitting line. All items in the PLM range are silicone free.
