Product Introduction
Rubber Seals are essential mechanical components used to prevent the leakage of liquids or gases, keep out contaminants (dust and moisture), and maintain internal pressure between two joined surfaces or parts.
Primary Functions
Leakage Prevention: Creates a tight barrier to contain fluids or gases within a system.
Contamination Control: Blocks dust, dirt, and water from entering sensitive internal mechanisms.
Pressure Retention: Ensures the system maintains its required operating pressure for efficiency and safety.
Common Types & Shapes
O-Rings: The most common circular seal with a round cross-section, used in both static and dynamic applications.
Oil Seals (Rotary Shaft Seals): Designed to seal rotating shafts and keep lubricants inside while preventing dirt entry.
Gaskets: Flat seals used between two stationary flanges (e.g., engine blocks or pipe joints).
V-Rings & U-Cups: Specialized lip seals typically used in hydraulic and pneumatic piston applications.
Key Materials
Selecting the right elastomer is critical based on the environment:
Nitrile (NBR): The "standard" for oil and fuel resistance.
Viton (FKM): High-end material for extreme heat and aggressive chemicals.
Silicone (VMQ): Excellent for food-grade and medical use due to its non-toxic nature and wide temperature range.
EPDM: The best choice for outdoor weather, steam, and water resistance.
Critical Specifications
Hardness: Measured in Shore A (typically 50A to 90A); harder seals handle higher pressure, while softer seals conform better to rough surfaces.
Compression Set: The ability of the rubber to return to its original thickness after being squeezed; a low compression set ensures a long-lasting seal
