Gaskets play a crucial role in many industries, acting as a seal to prevent leaks between two surfaces. Different environments, chemicals, and temperatures call for specific types of gasket materials, each with unique properties. Below, we’ll explore four common gasket types: FPM (Viton®) Gaskets, EPDM Gaskets, NBR Food Gaskets, and NBR Gaskets—detailing their suitability, uses, and key industries they serve.

1. FPM (Viton®) Gaskets
Why Choose FPM Gaskets?
FPM gaskets, often known by the brand name Viton®, are highly versatile and durable, particularly in applications involving exposure to harsh chemicals or high temperatures. Their broad chemical compatibility and excellent resistance to oils, fuels, and acids make them an ideal choice for industries where longevity and reliability are essential.
Suitable For:
- Fuels
- Acids
- Scale removers
- Water-proofing agents
- Impregnating agents
- Anti-mould agents
- Oils & lubricants
- High-temperature exposure
- Harsh chemicals
Uses:
- Lubrication systems
- Cleaning applications
Industries:
- Automotive: Known for their resistance to fuels, oils, and high temperatures, FPM gaskets are often used in fuel systems and under-the-hood applications.
- Aerospace: The ability to withstand extreme conditions makes them ideal for sealing systems exposed to jet fuel and other harsh chemicals.
- Industrial Cleaning: FPM gaskets are resistant to corrosive cleaning agents and scale removers, making them valuable in industrial maintenance and cleaning systems.
2. EPDM Gaskets
Why Choose EPDM Gaskets?
EPDM (Ethylene Propylene Diene Monomer) gaskets offer exceptional resistance to water, steam, and a variety of chemicals, making them the go-to choice for sealing systems that deal with water-based solutions. Their excellent durability in harsh environmental conditions, including UV and ozone exposure, adds to their appeal for outdoor and industrial applications.
Suitable For:
- DetergentsScale removersBleaching agentsAlcoholsDisinfectantsHydraulic fluidsWater-based applications Uses:
- Lubrication systemsCleaning applications Industries:
- Automotive: EPDM gaskets are often used for sealing brake systems and cooling systems, as they provide excellent resistance to hydraulic fluids and extreme weather conditions.
- Plumbing: Due to their water and steam resistance, EPDM gaskets are frequently used in plumbing applications, especially in seals for pipes and fittings.
- HVAC: EPDM’s strong resistance to ozone and UV exposure makes it perfect for use in heating, ventilation, and air conditioning systems.
3. NBR Food Gaskets
Why Choose NBR Food Gaskets?
NBR (Nitrile Butadiene Rubber) food gaskets are specifically designed to resist oils, fats, and food-grade fluids, making them perfect for use in the food and beverage industry. Their compliance with food safety regulations ensures that they can be used in sensitive environments where maintaining purity and cleanliness is essential.
Suitable For:
- Liquid food solutions (oils, fats, and other food-grade fluids)
Uses:
- Sealing systems in food processing
- Beverage industry equipment
Industries:
- Food & Beverage: NBR food gaskets are engineered to meet strict hygienic standards and are widely used in equipment that handles oils, fats, and other food-grade fluids. From beverage machines to food preparation lines, these gaskets ensure contamination-free sealing.
4. NBR Gaskets
Why Choose NBR Gaskets?
NBR gaskets are known for their excellent resistance to oils, fuels, and hydraulic fluids, making them a dependable choice for sealing applications in heavy-duty environments like automotive systems, industrial machinery, and gas pipelines.
Suitable For:
- Water and aqueous solutions
- Phytosanitary fluids
- Oil
- Hydraulic fluids
- Gas
Uses:
- Building and construction
- Automotive
- Gas systems
Industries:
- Building & Construction: NBR gaskets are commonly used in plumbing and gas systems, ensuring leak-proof seals in piping systems.
- Automotive: Like FPM gaskets, NBR gaskets are popular in the automotive industry for their compatibility with oils, fuels, and hydraulic systems.
- Oil & Gas: Due to their resistance to oil and gas, NBR gaskets are widely used in sealing systems for pipelines and other oil and gas infrastructure.
Conclusion
The choice of gasket material can have a significant impact on the efficiency and safety of a system. Whether you’re dealing with food processing, automotive systems, or industrial applications, understanding the unique properties of FPM, EPDM, and NBR gaskets will help you ensure optimal performance and reliability.
