01 / PRODUCT FOCUS
One small seal.
Many precise profiles.
Rubber O-rings for industrial applications in India. Explore the profile, then define the material and dimensions.
01 / CROSS-SECTION
Standard & metric O-rings
A circular cross-section for static and selected dynamic sealing. Specify the size, compound and operating conditions.
Explore profile ↗02 / CROSS-SECTIONSquare rings & washers
Flat faces and a square or rectangular section. Match the profile to the drawing and the intended sealing arrangement.
Explore profile ↗03 / CROSS-SECTIONQuad rings / X-rings
A four-lobed sealing profile. Check the gland, movement and compound when evaluating an alternative to an O-ring.
Explore profile ↗04 / CROSS-SECTIOND-rings
A rounded sealing face with a flat side. A dedicated profile needs its own dimensions and gland assessment.
Explore profile ↗05 / CROSS-SECTIONCustom rubber products
Rubber bushes, mounts and grommets developed around a drawing, sample or application requirement.

Hydraulic seals
Rod, piston, wiper and guide products are planned for a later release.
Profile diagrams show cross-section concepts, not finished-product drawings. Availability and final specifications are confirmed against the enquiry.
02 / MATERIAL INTELLIGENCE
The right material.
The difference that matters.
Every environment asks something different of a seal. Start with the material, then specify the compound.

DIMENSIONS / PRECISION, DEFINED
Every dimension
has a purpose.
A clear specification starts with two measurements. Add the operating conditions to make it an engineering brief.

Read selection guide↗Small ring.
Big responsibility.
An O-ring seals between mating surfaces. Its circular cross-section deforms inside a correctly designed groove.
Same shape.
Different strengths.
NBR, HNBR, FKM, EPDM, silicone and neoprene serve different conditions. Colour alone cannot identify a compound.
The right fit.
Beyond dimensions.
Size is the starting point. Fluid, temperature, pressure and movement complete the specification.

Read material guide ＋Frequently asked
How do I specify an O-ring?
State inside diameter, cross-section, units, compound, hardness, fluid, temperature, pressure and quantity. Include a drawing or standard reference when available.
Does colour identify the material?
No. Colour is not a reliable material identifier. Confirm the compound code and supporting documentation.
Is there one universal pressure rating?
No. Pressure capability depends on the compound, hardness, clearance, temperature and seal arrangement. Use an application-specific review.
Can I choose an O-ring by size alone?
No. Two identical sizes can behave differently because of their material, hardness and operating environment.
