Rubber Gasket Materials
Selecting the right rubber gasket material is critical for sealing reliability, safety, and long service life. Different elastomers offer specific properties such as heat resistance, oil resistance, chemical compatibility, and compression set performance. Material selection must match operating pressure, temperature range, and process media to ensure effective sealing and prevent premature failure. Industrial rubber gasket materials are manufactured to meet international standards such as ASME B16.21, DIN, and EN 1514-1, ensuring dimensional accuracy and consistent performance. Choosing the appropriate elastomer improves sealing efficiency, reduces maintenance, and supports long-term equipment reliability in demanding applications.
Ring gaskets are manufactured using various materials based on the application’s requirements. The material selection depends on factors such as the type of fluids being sealed, operating conditions (including temperature and pressure), and the overall environment.

Answers to all your possible questions.
What is a rubber gasket used for?
A rubber gasket is used to create a leak-proof seal between two mating surfaces in pipelines, flanges, valves, pumps, and industrial equipment. It prevents leakage of liquids, gases, steam, and chemicals under pressure and mechanical load.
How do I choose the right rubber gasket material?
Selecting the correct rubber gasket material depends on operating temperature, pressure rating, and chemical exposure. For oil and fuel applications, NBR or FKM is recommended. For water and steam systems, EPDM performs best. Silicone is preferred for food-grade and high-temperature environments. Material compatibility ensures long-term sealing reliability.
Which rubber gasket material is best for oil and fuel resistance?
Nitrile (NBR) and Viton™ (FKM) are commonly used for oil and fuel resistance. NBR is suitable for general petroleum-based applications, while FKM provides superior resistance in high-temperature and aggressive chemical environments.
What is the temperature range of rubber gaskets?
Rubber gasket temperature range depends on the elastomer type. Silicone and FKM offer high-temperature resistance, EPDM performs well in steam systems, and NBR is suitable for moderate temperature oil applications. Always match the material rating with operating conditions.
Are rubber gaskets suitable for chemical applications?
Yes, rubber gaskets can be used in chemical processing systems when the correct elastomer is selected. FKM and EPDM are commonly used depending on the type of chemicals, temperature range, and pressure conditions
Are rubber gaskets suitable for high-pressure systems?
Rubber gaskets can be used in medium to high-pressure applications when designed with proper thickness, hardness (Shore A), and flange compatibility. Raised face configurations are typically preferred for higher pressure sealing.
What standards do rubber gaskets comply with?
Industrial rubber gaskets are commonly manufactured in accordance with ASME B16.21, DIN, EN 1514-1, and BS flange standards to ensure dimensional accuracy and sealing performance compatibility.
Which rubber gasket is best for high temperatures?
For high-temperature applications, Silicone and Viton™ (FKM) rubber gaskets are typically recommended. Silicone performs well in extreme temperature environments, while FKM offers superior heat and chemical resistance in demanding industrial systems.
What thickness should a rubber gasket be?
Rubber gasket thickness depends on flange condition, pressure class, and surface finish. Standard thickness ranges from 1.5 mm to 6 mm, but custom thickness can be manufactured based on application requirements.
How do I install a rubber gasket correctly?
To install a rubber gasket, ensure the flange surfaces are clean, smooth, and aligned. Place the gasket evenly, tighten bolts in a crisscross pattern to the recommended torque, and avoid over‑compression, which can reduce gasket life. Proper installation prevents leaks and premature failure.
How long does a rubber gasket last?
The lifespan of a rubber gasket depends on the material, operating conditions, and maintenance. Under normal use, NBR and EPDM gaskets may last 5–10 years, while FKM and silicone can perform longer in high‑temperature or chemical environments. Regular inspection and replacement schedules ensure reliable sealing.
Are rubber gaskets food‑grade safe?
Yes, certain rubber materials such as silicone and EPDM are FDA‑approved for food and beverage applications. They resist high temperatures, steam, and cleaning chemicals, making them suitable for hygienic processing environments.
What is the difference between rubber gaskets and metal gaskets?
Rubber gaskets provide flexibility and chemical resistance, making them ideal for low‑ to medium‑pressure systems. Metal gaskets, such as spiral wound or ring type joints, are used in high‑pressure, high‑temperature, and critical sealing applications. The choice depends on system requirements.
Can rubber gaskets be customized?
Yes, rubber gaskets can be custom-manufactured in specific dimensions, hardness levels, and material grades to match non-standard flange sizes or specialized industrial requirements.
