EPDM Rubber Gasket
High-performance EPDM rubber gaskets for waterproof, outdoor, and industrial sealing applications.
Custom EPDM gaskets with excellent weather, ozone, and UV resistance
Premium EPDM Rubber Gasket Manufacturer: Extreme Weather & Water Sealing
For the past twenty years, as a leading EPDM rubber gasket manufacturer, RiseUp has been producing heavy-duty EPDM gaskets engineered to withstand decades of ozone exposure, UV radiation, and harsh weather conditions without hardening or degradation.
From high-volume die-cut flange gaskets to continuously extruded weatherproof rubber seals, we provide complete turnkey elastomer solutions precisely tailored to your applications.

-40°C to +150°C Rated
The Ultimate Shield Against Weather, Ozone, and Water
When it comes to permanent outdoor exposure, standard rubber formulations fail quickly. Many local EPDM rubber gasket suppliers in Europe and North America can only provide commercial-grade materials that are prone to UV degradation, and due to high labor costs, their prices are still expensive.
Our highly saturated EPDM polymer backbone makes it virtually immune to damage from sunlight and atmospheric conditions, while offering better cost performance.
This is why engineers from European and American customers often bypass standard EPDM gasket suppliers and specify our EPDM rubber gaskets for the most demanding environments.
☀️ Unmatched UV & Ozone Resistance: Unlike natural rubber or standard nitrile, custom rubber gaskets made from EPDM will not crack, fade, or lose their critical elasticity even after decades of direct sunlight and harsh atmospheric exposure.
💧 Superior Water & Steam Sealing: Highly impermeable to water and highly resistant to hot steam. This makes EPDM the premier choice for HVAC systems, water treatment plants, and architectural weatherstripping.
🌡️ Broad Temperature Flexibility: Our standard EPDM compounds maintain excellent flexibility in freezing conditions down to -40°C (-40°F) and reliably resist heat aging up to +150°C (+302°F).
🛑 The Honest Engineering Disclaimer: We believe in complete transparency to prevent catastrophic system failures. EPDM is not suitable for environments exposed to petroleum, mineral oils, or concentrated hydrocarbons (these will cause the EPDM to swell and degrade). If your application involves active oil contact, our engineering team will seamlessly guide you toward our nitrile rubber gasket or fkm rubber gasket
Engineered EPDM Grades for Specialized Applications
Not all EPDM rubber is created equal. Depending on your industry’s regulatory requirements, continuous thermal stress, and closure force limits, our materials science lab compounds specific EPDM elastomer grades to ensure the long-term reliability of your custom rubber gaskets:
🏢 Commercial Grade EPDM: The standard, highly cost-effective workhorse. Ideal for general-purpose architectural weatherstripping, HVAC duct sealing, and agricultural equipment where reliable UV and moisture resistance is required.
🔥 Peroxide-Cured EPDM (High-Performance): While standard sulfur-cured EPDM is common, we highly recommend our Peroxide-Cured epdm rubber gaskets for extreme environments. This advanced curing process provides vastly superior heat resistance (up to +150°C / +302°F), remarkable chemical stability, and an exceptionally low compression set. It is the ultimate choice for high-pressure steam lines and automotive cooling systems.
🚰 Potable Water Grade (NSF-61 / WRAS): Formulated strictly for the municipal water and plumbing industry. These ultra-clean, non-toxic EPDM gaskets are certified safe for contact with human drinking water. They prevent any chemical leaching, bacterial growth, odor, or taste transfer in pipe flanges and water filtration systems.
🧽 Closed-Cell EPDM Sponge: When your application requires a rugged outdoor IP67/IP68 waterproof seal but the housing has a low closure force (such as outdoor LED lighting fixtures or thin plastic electrical enclosures), our custom extruded or molded EPDM sponge offers extreme compressibility and immediate weatherproofing.
Advanced Manufacturing: Die-Cut Gaskets & Extruded Weather Seals
No matter what stage or scale your project is at, RiseUp has the in-house machinery and engineering expertise to turn your design into reality. We adopt a dual-engine manufacturing model to produce both flat EPDM rubber gaskets and continuous rubber seal profiles with uncompromising precision:
1. High-Speed Precision Die-Cutting (For Flat & Flange Gaskets)
Ideal for large-volume industrial piping flanges, HVAC ducting, and flat environmental sealing applications.
Core Advantages:
Lightning-fast production speed and extremely low tooling cost. We use advanced CNC tool-free cutting (waterjet/flash cutting) for rapid prototyping, typically completed within 2–3 days, and high-speed rotary die-cutting or flatbed die-cutting for mass production.
High Customization:
We can apply premium pressure-sensitive adhesive (PSA) to your flat EPDM gaskets, enabling fast “peel-and-stick” assembly on your production line.
2. Continuous Custom Extrusion (For Weatherstripping & Profile Seals)
Perfect for architectural doors and windows, automotive door seals, and outdoor enclosure weatherproofing.
Core Advantages:
We extrude EPDM rubber into continuous custom cross-sections such as D-profile, P-profile, T-profile, l Shape as well as ribbed and U-channel designs.
Co-Extrusion Capability:
Need a rigid mounting base with a soft sealing lip? We can co-extrude solid EPDM and closed-cell EPDM sponge into a single high-performance weatherstrip seal.
Trusted EPDM Rubber Gaskets for Heavy-Duty Industries
Over the past twenty years, OEM engineers and infrastructure procurement managers have trusted RiseUp to protect their critical systems from harsh environmental conditions. Our heavy-duty elastomer solutions are deeply optimized and specifically engineered to perform in the following four major application areas with demanding environmental and fluid sealing requirements:
Water & Wastewater Treatment

Construction & HVAC Systems
Delivering architectural window glazing seals, expansion joint fillers, and robust HVAC ducting gaskets. Our custom rubber gaskets ensure commercial building envelopes remain perfectly insulated against driving rain, freezing drafts, and extreme solar heat
Outdoor Electrical & Telecom Enclosures
Manufacturing highly compressible closed-cell EPDM sponge profiles and precision molded rubber seals for outdoor LED lighting fixtures, smart meters, and telecom junction boxes. Guaranteed to maintain an IP67/IP68 rating against dust and moisture ingress
Custom EPDM Gaskets Capability
We provide custom EPDM gaskets in various sizes, shapes, hardness levels, and sealing structures based on your drawings or samples.
Frequently Asked Questions About Custom EPDM Gaskets
Sulfur-cured is for general weatherproofing. Peroxide-cured EPDM offers vastly superior heat resistance (up to +150°C) and low compression set, making it mandatory for high-pressure steam and automotive cooling
Yes. We laminate high-performance PSAs, our materials before precision die-cutting, ensuring fast “peel-and-stick” assembly for your flat epdm rubber gaskets
No. Unlike generic epdm gaskets suppliers who might overpromise, we warn that EPDM rapidly degrades in petroleum. For oil environments, use our nitrile rubber gasket
Both excel outdoors, but EPDM provides superior physical tear strength and abrasion resistance. Choose Silicone only for extreme heat (>+150°C) or strict FDA food-grade compliance
It is a material’s failure to return to its original thickness. Our premium EPDM features a low compression set, ensuring your rubber seal maintains a permanent, watertight barrier under continuous pressure
Solid EPDM handles high clamping forces (e.g., pipe flanges). Closed-cell EPDM sponge is highly compressible, ideal for achieving IP67 sealing on low-closure-force plastic enclosures
Yes. While black maximizes UV resistance, we can compound EPDM into custom colors (grey, white, architectural bronze) to match building facades without sacrificing sealing performance.
Yes. We compound specific grades that are fully NSF-61 and WRAS certified. These ultra-clean epdm gaskets ensure no toxic chemicals or odors leach into municipal potable water systems.
