Rubber Material Selection Guide
Choosing the right elastomer is the single most important decision in seal performance. The wrong compound leaks, hardens, swells or cracks; the right one runs for years. Use the guide below to match material to your operating conditions, then talk to our team to confirm the grade.

Frequently Asked Questions
Can rubber seals handle pressure and mechanical stress?
Yes, rubber seals are built to handle pressure and mechanical stress while maintaining a reliable seal.
Are rubber seals reusable or one-time use?
Many rubber seals can be reused if they're in good condition, though some high-pressure applications may need replacements.
Why choose Modern Rubber & Plastic for rubber seals?
We offer durable, high-quality rubber seals that can be customized to fit a wide range of industrial and automotive needs.
Can rubber seals be made in custom sizes and shapes?
Yes, we can manufacture rubber seals in any size, shape, or material to suit your specific requirements.
Which rubber seal material is best for chemical resistance?
The Viton (FKM) and Nitrile (NBR) are excellent choices for resistance against chemicals, oils, and harsh environments.
Can you manufacture rubber seals from our drawing or a physical sample?
Yes. We manufacture custom rubber seals to your engineering drawing, a physical sample, or your written specification. If you have a sample, we analyse its dimensions and material properties, develop the mould, and provide trial samples before bulk production.
Which rubber material should I choose for my application?
It depends on the media, temperature and pressure. As a guide: NBR for oils and fuels, EPDM for water, steam and weather, Viton (FKM) for high heat and chemicals, Silicone for extreme temperatures and hygienic service, and Neoprene for balanced general-purpose duty. Share your operating conditions and we'll recommend the right compound.
Do you supply standard sizes or only custom seals?
We are primarily a custom manufacturer of seals and other rubber products — they are produced to your required size, profile and material.
Do you export rubber seals outside India?
Yes. We supply customers internationally, including Europe, the Middle East and Africa, alongside our domestic customers across India.
Can you manufacture custom rubber seals from a physical sample or technical drawing?
Yes. We can manufacture seals from physical samples, 2D drawings (PDF/DWG), or 3D CAD models (STEP/IGES).
How do I know which rubber material is right for my application?
Material selection depends on the operating media, temperature, and movement. Common options include NBR for oils, EPDM for steam and outdoor use, and FKM/Viton® for aggressive chemicals.
What is the difference between an O-Ring and a Quad Ring (X-Ring)?
An O-Ring has a round cross-section, while a Quad Ring has an X-shaped cross-section. Quad Rings provide better sealing, reduce twisting, and retain lubrication more effectively.
