⭐ 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:

• Liquid
• Oil
• Gas
• Air
• Water
• Steam
• Chemicals
• Fuel

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.

 

🧪 FULL MATERIAL SELECTION – TECHNICAL DETAIL

RUBASIA RUBBERTECH INDUSTRIES produces O-rings in every industrial elastomer:

 

1. NBR (Nitrile Rubber) – 40% → 70% ACN

✓ Performs well with steam, hot water
Used in building systems in Kota Kinabalu, Kuching, Miri, Bandar Seri Begawan.

 

3. Silicone (VMQ)

✓ Ultra-high temperature resistance

✓ Extremely flexible
Used in food factories in Sibu, Bintulu, Tawau.

 

4. Viton (FKM / Fluoroelastomer)

🏗️ 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:

• Dovetail gland
• Rectangular gland
• Half-round groove
• Piston-type groove
• Rod-type groove

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:

• Flanges
• Pipe joints
• Manifolds
• Covers & housing caps

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:

• Hydraulic cylinder rods
• Pistons
• Rotating shafts

Dynamic applications require materials with:

• Low friction
• Excellent wear resistance
• High elasticity
• Low compression set

Used heavily in timber factories (Sarawak), palm oil mills (Sabah), and marine applications (Brunei).

 

🌡️ TEMPERATURE & PRESSURE RANGE (Typical)

Material	Temp Range	Pressure Range
NBR	-40°C to 120°C	Up to 40 MPa
EPDM	-50°C to 150°C	Up to 20 MPa
Silicone	-60°C to 230°C	Up to 10 MPa
Viton	-20°C to 250°C	Up to 50 MPa
PTFE	-200°C to 260°C	Up to 100 MPa

🧱 TOLERANCES & DIMENSIONAL CONTROL
