Frequently Asked Questions

Whether you are selecting a rubber material or designing a sealing solution, these answers will help you make the right decision.

What is an O-Ring?

An O-Ring is a circular rubber seal designed to prevent leakage between two mating surfaces. It is widely used in hydraulic, pneumatic and industrial equipment.

How do I choose the correct rubber material?

Selection depends on temperature, pressure, chemicals, oil exposure and environmental conditions. Materials like NBR, EPDM, Silicone and FKM each have different properties.

What is the difference between a Rubber Seal and a Washer?

A rubber seal prevents leakage of liquids or gases, while a rubber washer mainly distributes load and provides cushioning between two surfaces.

Why do rubber parts fail?

Improper material selection, excessive temperature, chemical attack, aging, incorrect installation and poor storage are the most common reasons.

Can Pooja Rubber manufacture custom rubber parts?

Yes. We manufacture custom O-Rings, Rubber Seals, Gaskets, Bushes, Washers and molded rubber components according to customer drawings or samples.
