+P INTRODUCTION: WHAT IS AN O-RING?
A Rubber O-Ring, also known as a Rubber Sealing Ring, is a precision-engineered, circular elastomer component with a uniform round cross-section. It functions as a mechanical gasket that prevents the escape of:
O-rings work through compression-based sealing. When placed inside a groove (called a gland), the O-ring is squeezed between two mechanical surfaces. This controlled compression causes the elastomer to deform, expand, and occupy all microscopic gaps, creating a fluid-tight and gas-tight barrier.
O-rings are widely used because they are:
Extremely reliable
Low cost
Easy to install
Suitable for static & dynamic motion
Compatible with a wide range of temperatures & pressures
They are used in millions of engineering systems, from simple plumbing fittings to high-pressure industrial hydraulic machinery.

MANUFACTURING METHODS – TECHNICAL ENGINEERING
RUBASIA RUBBERTECH INDUSTRIES produces O-rings using various specialized processes:
1. Compression Moulding
Used for large-diameter O-rings
Creates durable, heavy-duty sealing rings
2. Injection Moulding
Used for small-to-medium high-precision O-rings
Creates extremely accurate tolerances (±0.03mm)
3. Transfer Moulding
Used for multi-cavity production
Ensures excellent surface finish
4. Extrusion + Vulcanized Splicing
Used to produce GIANT O-rings (up to 3 meters or more)
5. Post-Curing Oven Treatment
Enhances chemical resistance
Stabilizes mechanical properties
SHAPE & CROSS-SECTION ENGINEERING
O-rings always have:
Round outer diameter
Round cross-section
Match groove dimensions precisely
Work in radial or axial sealing
Groove types:
These groove designs affect compression, squeeze percentage, friction, chemical compatibility, and sealing performance.
STATIC VS DYNAMIC APPLICATIONS – SUPER DEEP EXPLANATION
Static O-Ring Sealing
Used when parts do NOT move
Example:
Static O-rings are used widely in:
Kota Kinabalu, Tawau, Kuching, Miri, Brunei Darussalam.
Dynamic O-Ring Sealing
Used when surfaces move against each other
Example:
Dynamic applications require materials with:
Used heavily in timber factories (Sarawak), palm oil mills (Sabah), and marine applications (Brunei).
