30" to 36" ID X 0.313" (8.00mm) C/S EPDM 70 Vulcanized O-Ring

762mm ID to 914mm ID / 30" to 36" ID

Spliced & Vulcanized O-Rings - Current typical lead time is 5-10 days for up to 10 O-Rings. More than 10 pieces may take 10-15 days depending on cord stock. 

Spliced and vulcanized o-rings are a great solution when standard o-rings cannot be used or cannot be purchased quickly. Spliced o-rings are made from extruded o-ring cord and then vulcanized to form the o-ring size (ID) required. The O-ring Store provides seamless spliced Standard Inch & Metric O-rings in all of the standard materials in a variety of cross sections, as well as Splicing Kits.

This process allows for custom sizes larger and different than standard molded o-rings.

EPDM (Ethylene Propylene, EPM)

EPDM is a copolymer of ethylene and propylene. Ethylene propylene diene monomer (EPDM) is 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. Heat resistance-Up to 300°F (149°C) (max. 400°F (204°C) in water and/or steam).
Cold flexibility-Down to approximately –70°F (–57°C).

Chemical resistance:

• Hot water and steam up to 300°F (149°C) with special compounds up to 400°F (204°C)
• Glycol based brake fluids up to 300°F (149°C)
• Many organic and inorganic acids
• Cleaning agents, soda and potassium alkalis
• Phosphate-ester based hydraulic fluids (HFD-R)
• Silicone oil and grease
• Many polar solvents (alcohols, ketones, esters)
• Ozone, aging and weather resistant.

Not compatible with:Mineral oil products (oils, greases and fuels).
