EPDM Rubber Parts
Vip Rubber & Plastic manufactures custom EPDM rubber parts, extrusions, and molded components known for excellent resistance to ozone, mild acids, detergents, alkalis, silicone oils, alcohol, and ketones. Due to its environmental resistance, this material is commonly used in applications in the aerospace, marine, architecture, HVAC, and construction industries.
EPDM is a copolymer of ethylene and propylene combined with a diene comonomer, which is where the material gets its name. This composition makes EPDM more economical than silicone while still holding up to demanding outdoor and industrial conditions. Whether you need standard EPDM gaskets and seals or a fully custom EPDM extrusion, our team engineers every part to your exact specifications.

Note: Custom EPDM rubber parts should not be used in applications exposed to petroleum-based products or environments with exposure to aromatic hydrocarbons. If your application involves oil, fuel, or hydrocarbon exposure, Nitrile (NBR) or FKM/Viton may be a better-suited material. Our team can help you compare options.
Common Applications for EPDM
Part Types
EPDM is an extremely versatile material that can be used in a wide variety of products, including:
- Seals
- Gaskets
- Aircraft Tubing
- Window Seals
- Weather Stripping
- Setting Blocks
- Rubber Sheet & Rolls
- O-Rings
- Rubber Cord
- Extruded Profiles
Industries
With excellent resistance to weather, heat, and low-temperature flexibility, custom EPDM rubber parts are used across industries, including:
- Aerospace: Window seals, aircraft tubing, and sealing solutions for aircraft manufacturing and maintenance
- Automotive: Door and window seals, weather stripping, and vibration components
- Military & Defense: Seals, gaskets, tubing, and sheet for demanding field conditions
- Architectural Glass & Metal: Window glazing seals and setting blocks
- Electrical: Connector seals, covers, and washers
- HVAC & Construction: Weather sealing and washdown-resistant components for hot and steam exposure
- Maritime: Marine-grade seals and gaskets resistant to weather and ozone
- Medical: Seals and components requiring chemical resistance
- Food & Beverage: Food-grade EPDM for washdown and moisture resistance
EPDM vs. Silicone
EPDM rubber parts and silicone share similar weather and ozone resistance, but EPDM is generally more economical and performs well across a -20°F to +350°F range. Silicone offers a wider temperature range and better compression set, but at a higher cost. Our team can help you determine which material best fits your application's performance and budget requirements.

FAQs
1. What is EPDM rubber used for?
EPDM rubber is used for seals, gaskets, weather stripping, window seals, tubing, and sheet products. Its excellent ozone, weather, and chemical resistance make it common in automotive, aerospace, architectural, HVAC, marine, and food & beverage applications. Vip Rubber & Plastic manufactures custom EPDM parts for these industries.
2. What makes EPDM rubber different from silicone?
EPDM and silicone both resist ozone and weathering, but EPDM is more cost-effective and performs reliably from -20°F to +350°F, while silicone offers a wider temperature range. Silicone also has better compression set, but usually comes at a higher price point. The right choice depends on your application's performance needs and budget.
3. Can EPDM rubber be used with oils or fuels?
No. EPDM has poor oil resistance and should not be used in applications exposed to petroleum-based products or aromatic hydrocarbons. For oil, fuel, or hydrocarbon exposure, materials like Nitrile (NBR) or FKM/Viton are better suited. Our team can help identify the right material for your application.
4. What industry specifications does EPDM meet?
Vip Rubber & Plastic manufactures EPDM rubber parts to specifications including HH-G-156 Type 2 and 3, AMS-3248C, AMS-3253A, AMS-3260C, AMS-R-83285A, and ASTM-D-2000 classifications M1CA407 and M2CA507. Contact our team to confirm availability for additional or custom specifications.
5. Is EPDM rubber food-grade safe?
Yes, food-grade EPDM is available and commonly used in food and beverage manufacturing for washdown-resistant seals and moisture-resistant components. It withstands repeated cleaning and sanitation cycles, making it suitable for hygienic processing environments. Contact us to confirm food-grade compliance for your specific application.
