 What is E.P.D.M? Fast growing synthetic rubber having both specialty and general-purpose applications.  Ethylene Propylene Diene Monomer  Also called E.P.T or E.P.R  Particularly useful when sealing hydraulic fluids on valves & Floating Flanges  They are usually black in color and come as ‘RINGS’  Universal & Economical Product Retrieved from: oringsdubai.files.wordpress.com

 General Characteristics  Temperatures Ranges from 13°F(-25°C) to 250°F(120°C)  Excellent Abrasion Resistance  Good Resistance to Tearing  Generally resistant to: Alcohols, Acidic salts, Alkaline salts, Alkaline solutions, Beverages, Bleach, Inorganic acids (dilute), Neutral salts, Water (cooling, brackish, salt), Hot Water, Steam.  Generally not resistant to: Chlorinated hydrocarbons, hydrocarbon solvents & oils, petroleum-based oils, turpentine.

 EPDM Ring Seal  A LIP sealing ring constitutes the seal between socket and spigot end. The lip sealing ring ensures quick and efficient jointing of the pipe system while providing a tight seal in case of both pressure and vacuum. Retrieved from: blucherdrains.com

 EPDM Door & Window Seals  EPDM rubbers could also be used for door and window seals, due to its ease to compress, hollow shape giving an optical tightness, and very good aging properties. Retrieved from: weiku.com

 Reference to AMCO Europe B.V  4 Common Floating Flange Joints  Type SF – 130  Type SF – 105  Type SF – USA  Type SF - DF

 TYPE SF – 130  TYPE SF – 105  TYPE SF – USA  TYPE SF – DF  These are the types of joints that EPDM rubber is used in with Floating Flanges.
