At RCF Bolt & Nut, we supply and manufacture high-quality EPDM gaskets and Viton gaskets for a wide range of industrial and commercial sealing applications across the UK.

Designed for reliability in demanding environments, our gasket solutions are suitable for use in systems exposed to high temperatures, chemicals, oils, weathering, and moisture, with options available for both standard and custom requirements.

EPDM Gaskets

What Are EPDM Gaskets?

EPDM gaskets are manufactured from Ethylene Propylene Diene Monomer rubber, a highly flexible synthetic elastomer known for its excellent resistance to weathering, ozone, UV exposure, water, and steam.

They are commonly used in low-pressure sealing applications, offering dependable performance in both indoor and outdoor environments where long-term durability is essential.

Key Benefits of EPDM Gaskets

• Excellent resistance to weather, ozone, and UV

• Suitable for water, steam, and mild chemical exposure

• Flexible and resilient across a wide temperature range

• Ideal for outdoor, plumbing, HVAC, and general industrial use

EPDM gaskets are widely specified in construction, automotive, pipework, and mechanical systems where exposure to the elements is a concern.

Viton Gaskets

What Are Viton Gaskets?

Viton gaskets are made from fluoroelastomer rubber and are designed for high-temperature and chemically aggressive environments. They offer outstanding resistance to oils, fuels, solvents, acids, and extreme heat.

These gaskets are commonly used in applications where standard rubber materials would fail, making them a preferred choice for critical sealing systems.

Key Benefits of Viton Gaskets

• Exceptional chemical resistance

• Excellent performance at high temperatures

• Long service life in harsh environments

• Ideal for fuel, oil, and chemical processing systems

Viton gaskets are widely used across automotive, aerospace, chemical processing, and industrial manufacturing sectors.

Frequently Asked Questions

What is the difference between EPDM and Viton gaskets?

EPDM gaskets are best suited for water, steam, weathering, and outdoor exposure, while Viton gaskets are designed for high temperatures and aggressive chemicals. Choosing the correct material depends on the operating environment and media being sealed. Both materials offer excellent sealing performance, but selecting the wrong type can lead to premature wear or failure.

Which gasket material is better for high temperatures?

Viton gaskets perform significantly better at high temperatures than EPDM. They are commonly specified for applications involving heat, oils, fuels, and chemical exposure. This makes Viton the preferred option for engines, industrial machinery, and high-temperature pipe systems.

Are EPDM gaskets suitable for outdoor use?

Yes. EPDM gaskets are highly resistant to UV, ozone, and weathering, making them ideal for outdoor installations such as HVAC systems, pipework, and external enclosures. They maintain flexibility over time, even in harsh conditions and fluctuating temperatures.

Can Viton gaskets handle oils and fuels?

Yes. Viton gaskets offer excellent resistance to oils, fuels, solvents, and hydrocarbons, making them suitable for automotive, industrial, and chemical processing applications. They are often used in environments where other rubber materials would swell, degrade, or lose sealing strength.

How do I know which gasket material I need?

If you’re unsure, our team can help. We’ll assess factors such as temperature, pressure, chemical exposure, and application type to recommend the most suitable gasket material. This ensures your gasket delivers the correct sealing performance and avoids unnecessary downtime or leaks.
