EPDM Metric O-Rings

EPDM O-Rings (EPR, EPM) Ethylene Propylene Diene Monomer

Ethylene-Propylene / EPDM O-Rings: Ethylene propylene rubber is an elastomer prepared from ethylene and propylene monomers (ethylene propylene copolymer). Our stock O-Ring compoundare made with an amount of a third (diene) monomer (ethylene propylene diene terpolymers). Ethylenepropylene-diene rubber (EPDM) produced using a third monomer and is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base. EPDM has outstanding resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight; but it is not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments. This popular rubber compound is usually the first choice for low torque drive belt applications.

Applications: Cold and Hot Water, Steam up to 300°F (149°C), Various Water / Municipalities Applications, Household Appliances, Glycol based brake fluids up to 300°F (149°C), Many organic and inorganic acid, Cleaning agents, soda alkali, potassium alkali, Phosphate-ester based hydraulic fluids (HFD-R), Silicone Oil, Silicone Grease, Many polar solvents (alcohols, ketones, esters), Ozone resistant, aging resistant, weather resistant, Outdoor Applications and Electrical Insulators..
Avoid: Mineral oil products (oils, greases and fuels), Solvents, Aromatic Hydrocarbons, Liquefied Petroleum Gas (LPG), Lubricating Oils, Petroleum Base Gasoline

Operating temperature: -65° to +300F°

Use Only O-Ring Silicone Lubricating Grease 3oz Tube on EPDM

Whether you need specialized O-Ring seals or off-the-shelf standard O-Ring seals, we have them all at great prices. Consider us as your source for specialty polymers, hightemperature performance, and chemical resistant O-Ring and seal application requirements. O-Ring selection is based on the chemical compatibility, application temperature, sealing pressure, lubrication requirements, quality, quantity and cost. That, combined with long list of materials from which you can chose from, plus the thousands of sizes—as well as numerous specifications specific to certain uses (aerospace, military, etc.) means that there are many thousands of possible combinations. Large manufacturers and distributors claim as many as 14,000 individual SKUs and tens of million unit in stock. We have 30,000 SKUs listed online and about 50 million O-Rings in stock.

Required O-Ring Information:

  • O-Ring Size (inch or metric) - Cross Section ( thickness ) X Inside Diameter
  • Temperature Requirements
  • Compound or Material Being Sealed
  • Operating Pressure - Durometer Rating
  • And of Course Quantity Required (Non-Stock O-Rings may require a minimum)

With this o-ring information we can assist you in finding an o-ring seal that matches your needs, via phone, email or live online chat. An additional consideration is compliance with use standards and specification such as have be established by the military, drinking water, food processing, aerospace, pharmaceutical, etc.
