Rubber gaskets and silicone gaskets are mechanical seals that fill the space between two or more mating surfaces. They stop leakage from or into the joined objects, and they hold the seal under compression, including high pressure under static conditions. Kesaria Rubber Industries, founded in 1989 in Gurgaon, India, makes custom-molded rubber gaskets by compression molding from high-quality rubber materials. Material and shape are tailored to your application, and Kesaria exports to 27+ countries.

How Rubber O-Rings Helps You

A properly designed rubber gasket is your system’s first line of defense. It keeps the seal reliable and safe under pressure, and it supports uptime and lower maintenance costs.
What the right gasket does:

Maintains seal integrity across compression and temperature shifts

Protects systems from contamination and environmental exposure

Reduces unplanned maintenance and lost production time

Guards against pressure-related failures in critical processes

Gives reliable performance in challenging operating conditions

You have questions.
We have answers.

What are rubber gaskets used for?

A rubber gasket serves as a mechanical seal between two surfaces, preventing leaks under high pressure and temperature fluctuations—ideal for static sealing applications such as piping systems, machinery, and process equipment.

What materials are Kesaria's gaskets made from?

Kesaria custom-molds gaskets from high-quality rubber materials including NR, SBR, NBR, CR, EPDM, HNBR, ACM, CSM, Silicone, and FKM (Viton®), each offering specific temperature and performance properties that suit varied industrial needs.

What specifications matter when selecting a gasket?

Key dimensions include inner diameter, outer diameter, thickness (working height), and rated working load. Performance factors like operating temperature and pressure range also impact the decision.

How do I choose the right rubber material for my gasket?

Kesaria offers a material selection guide for client's convenience. The guide shows temperature tolerances and performance ratings. For instance, Silicone can handle up to 230 °C, while EPDM offers good performance for steam applications.

What industries use these gaskets?

These gaskets are used in bathroom fittings, chemical processing, oil & gas, piping/plumbing systems, and water/wastewater management. Resilience and sealing effectiveness are the USPs of Kesaria gaskets.

Which rubber gasket material is best for high-temperature applications?

Silicone gaskets handle the highest temperatures, up to 230 °C, followed by FKM (Viton®) at 225 °C. ACM reaches 180 °C. EPDM, HNBR and CSM each reach 150 °C. For steam, Kesaria's guide rates CSM, silicone and FKM as Excellent, and EPDM and HNBR as Good. Share your operating conditions with Kesaria's engineers to confirm the right compound.

What happens if you use the wrong or ill-fitting rubber gasket?

An ill-fitting or wrongly selected gasket can cause fluid or gas leaks, pressure instability and contaminant intrusion. These problems can lead to equipment failure, downtime and higher maintenance costs. Choosing the right material and dimensions (inside diameter, outside diameter, thickness and working load) helps prevent them.
