PRODUCT FEATURES

Piston Valve Rubber Seal | Rubber Oil Seal

RUBASIA RUBBERTECH INDUSTRIES

 

🔥 1. High-Pressure Sealing Performance (Up to 500 Bar)

RUBASIA’s piston valve seals are engineered with high-durometer elastomers and precision-lipped geometry to maintain stable sealing even under:

• Hydraulic surge pressure
• Rapid pressure fluctuations
• Constant compression and decompression cycles
• Heavy-duty equipment loads

Ideal for hydraulic presses, palm oil mill machinery, excavators, forklifts, and marine winch systems operating in Sabah, Sarawak & Brunei.

 

🔥 2. Optimized Dynamic Sealing Lip Profile

The sealing lip features precision-molded edges that maintain uniform contact with the cylinder wall, ensuring:

• Smooth piston movement
• Reduced friction and heat generation
• Lower energy consumption
• Long lifespan even under continuous motion

This is crucial for fast-stroking cylinders, industrial valve actuators, and high-cycle pneumatic tools.

 

🔥 3. Superior Wear & Abrasion Resistance

With advanced polymers (NBR, Viton, PU), our seals resist:

• Scuffing
• Grooving
• Surface tear
• Material degradation from metal-to-rubber contact

This makes RUBASIA seals extremely durable in:

• Timber mills (Sibu, Kapit, Belaga)
• Construction machinery (Ranau, Keningau, Beaufort)
• Offshore rigs (Labuan, Miri, Brunei)

 

🔥 4. Multi-Lip and Dual-Action Seal Design

Available in single-lip, double-lip, multi-lip, and step-seal profiles, providing:

• Extra sealing redundancy
• Enhanced pressure retention
• Superior efficiency in both piston directions
• Better contamination isolation

Perfect for oil & gas, marine, heavy vehicles, and industrial automation.

 

🔥 5. High Chemical & Oil Resistance

Materials like NBR and Viton (FKM) offer strong resistance against:

• Mineral oils
• Hydraulic oils
• Diesel, petrol & kerosene
• Solvents, alkaline & acidic chemicals
• Grease, lubricants & transmission fluids

Critical for operations in:

• Oil refinery zones (Miri, Bintulu, Brunei)
• Heavy vehicle workshops (KK, Kuching, Sibu)
• Marine engine rooms (Labuan, Kota Kinabalu)

 

🔥 6. Temperature Resistance for Extreme Conditions

Different materials offer specialized temperature ranges:

• NBR: -30°C to +110°C
• EPDM: -40°C to +140°C
• Silicone: -50°C to +230°C
• Viton: -20°C to +250°C
• PU: -20°C to +120°C

Ensures performance in:

• Hot engine compartments
• Cold storage facilities
• Tropical outdoor machinery

 

🔥 7. Anti-Extrusion & Anti-Blowout Technology

Designed to prevent the seal from being forced out under extreme hydraulic pressure.
Features include:

• Reinforced sidewalls
• High-strength rubber formulations
• Anti-extrusion backing rings (optional)
• Tight radial interference fit

Especially important for industrial valves, hydraulic lifting systems, and marine actuators.

 

🔥 8. Ultra-Low Compression Set

Our seals maintain their shape and elasticity even after:

• Long-term compression
• High dynamic loads
• Intense reciprocating motion

This ensures the seal does not flatten or harden, preventing early leakage.

 

🔥 9. Contaminant-Blocking Outer Lip Design

Special outer lip prevents ingress of:

• Dust
• Sand
• Water
• Mill sludge
• Metal particles

Crucial for industries in Borneo with dusty/muddy environments:

• Plantation machinery (Lahad Datu, Sandakan, Tawau)
• Mining/logging machinery (Miri, Kapit, Bintulu)

 

🔥 10. Smooth Motion & Reduced Friction Operation

Special surface finishing provides:

• Low breakout force
• Silent piston motion
• Reduced piston rod wear
• Better lubrication retention

Perfect for precise systems used in:

• Automation lines
• Packaging machinery
• CNC machinery
• Testing equipment

 

🔥 11. UV, Ozone & Weather Resistance

EPDM, Neoprene & Silicone versions offer protection against:

• Ozone cracking
• UV degradation
• High-humidity tropical exposure

Ideal for outdoor machinery in:

• Papar
• Limbang
• Lawas
• Brunei Muara

 

🔥 12. Custom-Molded for Any Equipment Type

RUBASIA produces custom piston seals based on:

• Sample
• Drawing
• CAD file
• OEM specification
• Special industrial profile

We produce:

• U-cups
• V-packing
• Step seals
• Double-acting seals
• O-rings & X-rings
• Hydraulic rod seals
• Pneumatic piston seals

 

🔥 13. Reinforced Structural Options

Optional add-ons include:

• PTFE glide rings
• Fabric-reinforced layers
• Metal-core bonded seals
• Spring-energized lips
• Split-type piston seals

These upgrades enhance performance for high-demand industries.

 

🔥 14. Extremely Long Service Life (3–10x longer)

Through advanced compounding technology, RUBASIA seals offer:

• Higher elasticity retention
• Longer working hours
• Reduced maintenance downtime
• Lower total cost of ownership

Used widely in palm oil mills, marine vessels, timber mills, hydraulic workshops, and oil & gas operations.

 

🔥 15. Full Compliance with Global Industrial Standards

RUBASIA rubber seals meet:

• ISO 3601
• JIS B2401
• DIN 3771
• AS568
• ASTM rubber standards

Ensures compatibility with global machinery brands.
