 EXTENDED TECHNICAL DESCRIPTION

A piston valve rubber seal is a critical elastomer component engineered to maintain an airtight and fluid-tight seal between the piston and cylinder bore. It must endure constant movement, cyclic compression, oil contact, abrasion, and high-pressure fluctuations in industrial systems.

Our rubber oil seals and piston seals are engineered to:
 Maintain perfect sealing under speed variation
 Prevent leakage of oil, hydraulic fluid, air, or gas
 Minimize friction and wear of internal machinery
 Maximize the efficiency of hydraulic and pneumatic systems
 Prolong equipment life by preventing contamination ingress

�� DETAILED MATERIAL PERFORMANCE ANALYSIS

1� � Nitrile Rubber (NBR) Piston Seal

• Excellent resistance to petroleum-based oils
• Strong tear & abrasion resistance
• Ideal for hydraulic pistons in palm oil mills, machinery workshops, heavy machinery

2� � EPDM Rubber Seal

• Superior weather, ozone, and chemical resistance
• Performs well in steam, water systems, and outdoor equipment

3� � Neoprene Rubber Oil Seal

• Reliable in marine use, saltwater, chemical splash
• Used in shipyards (Labuan, Kota Kinabalu, Miri), marine engines, compressors

4� � Silicone Rubber Piston Seal

• Withstands extreme temperatures (-50°C to +230°C)
• Ideal for food-grade machinery, pharmaceutical factories, medical pumps

5� � Viton (FKM) High-Temperature Seal

• Exceptional chemical & fuel resistance
• Performs in harsh oil & gas environments
• Suitable for high-pressure pumps and refinery valves in Bintulu, Miri, Brunei O&G

� ADVANCED PRODUCT FEATURES (Ultra Detailed)

 High-Pressure Resistance

Built to withstand high PSI hydraulic systems used in construction, heavy machinery, and factory automation.

 Low Compression Set

Ensures long-term stability and prevents seal deformation even after prolonged usage.

 Dynamic Seal Stability

Minimal friction even under repetitive piston movement and high cycle counts.

 Multi-Lip and Single-Lip Designs

Available in U-cup, V-ring, O-ring, X-ring, double-acting, and custom profiles.

 Precision-Molded for Tight Tolerances

Achieves flawless sealing between piston and rod surfaces.

 Resistance to Oil, Fuel, Grease, Water & Chemicals

Ensures strong compatibility across industrial applications.

 Temperature Stability

Operates in both tropical outdoor heat (up to 120°C) and cold storage facilities.

 UV, Ozone & Weather Resistance

Ideal for long-term use in exposed environments (common across Sabah & Sarawak landscapes).

 Custom Manufacturing Options
