O-Rings
About
An O-ring is a mechanical gasket made from elastomeric materials. It is used to create a sealing barrier between two mating or adjoining surfaces to prevent the leakage of fluids or gasses. It is used across all types of engineering applications .
O-rings come in various cross-sectional shapes and sizes to accommodate different sealing applications. The choice of O-ring cross-section depends on factors such as the type of sealing required, the pressure, temperature, and the specific characteristics of the mating components.
O-ring materials play a critical role in ensuring the effectiveness and durability of these versatile sealing components. The choice of material depends on the specific application's requirements, including factors such as temperature, pressure, chemical compatibility, and wear resistance.
We produce O-rings in materials such as NBR, HNBR, EPDM, Silicone, Viton, FFKM,Chloroprene.
Salient Features
O-Rings
O-rings are among the most widely used sealing components, and at Harkesh Rubber LLP we manufacture them to deliver dependable performance across demanding applications. Each O-ring is designed for leak-proof sealing, durability, and resistance to extreme temperatures, pressure, and chemical exposure. To ensure consistent quality, every piece is cryogenically deflashed and inspected on a DOSS automated visual inspection system for accuracy and defect-free results.
Salient Features
- Cryogenically deflashed O-rings, inspected using DOSS automated visual systems
- Size range from 1.5 mm to 1200 mm with a dimensional tolerance of ±0.02 mm
- Temperature resistance from –60°C to +320°C (based on material)
- Millions of O-rings manufactured every day with consistent quality
- REACH, ROHS, EN 549, WRAS approved compounds
- Flash levels less than 0.10 mm
- Shore hardness options from 40–90 ShA, available in various colors
