Materials Guide
TYPE SEAL LINK MATERIAL PRESSURE PLATES BOLTS & NUTS TEMPERATURE RANGE (˚F) APPLICATIONS
E EPDM Black GLASS REINFORCED PLASTIC STEEL Zinc Dichromate -40˚ to +250˚ Suitable for most application in water, above ground and direct burial. Provides electrical insulation where cathodic protection is required.
ES EPDM Black GLASS REINFORCED PLASTIC STAINLESS STEEL (316) -40˚ to +250˚ Suitable for environments where the corrosion resistance of stainless steel hardware is required.
P NITRILE GLASS REINFORCED PLASTIC STEEL Zinc Dichromate -40˚ to +210˚ Resistant to most hydrocarbons, oil, gas, jet fuel, and many solvents.
PS NITRILE GLASS REINFORCED PLASTIC STAINLESS STEEL (316) -40˚ to +210˚ Same as above, but with corrosion resistance of stainless steel hardware.
K SILICONE STEEL Zinc Dichromate STEEL Zinc Dichromate -40˚ to +400˚ High temperature applications.

 

Wall Sleeves

 

Standard steel wall sleeves are positioned in the wall before the concrete is poured. Wall sleeves offer a cleaner installation for every engineered piping system.
