Rubber gaskets are mechanical seals designed to fill the space between two mating surfaces, preventing leakage, vibration, and environmental contaminants. They are essential components in industries such as automotive, plumbing, aerospace, and manufacturing, providing reliable sealing solutions under various pressures and temperatures.
Our rubber gaskets are manufactured to meet high standards of quality and performance. Below are the detailed parameters:
| Property | Value Range | Testing Standard |
|---|---|---|
| Hardness (Shore A) | 40 to 90 | ASTM D2240 |
| Tensile Strength | 10 to 25 MPa | ASTM D412 |
| Elongation at Break | 100% to 600% | ASTM D412 |
| Compression Set | 10% to 30% | ASTM D395 |
Our gaskets are available in custom sizes and standard dimensions. Common inner diameters range from 5mm to 500mm, with thicknesses from 1mm to 10mm. Tolerance levels adhere to ISO 3302-1 standards.
What factors should I consider when selecting a rubber gasket?
Consider the operating environment, including temperature range, pressure, chemical exposure, and media compatibility. Also, evaluate the material properties such as hardness, compression set, and compliance with industry standards.
How do I install a rubber gasket properly?
Ensure mating surfaces are clean, dry, and free of debris. Apply appropriate lubrication if needed, align the gasket correctly, and tighten bolts evenly in a crisscross pattern to avoid distortion and ensure a uniform seal.
What is the typical lifespan of a rubber gasket?
Lifespan varies based on material, application, and environmental conditions. Generally, high-quality gaskets can last several years under normal conditions, but extreme temperatures or aggressive chemicals may reduce this period.
Can rubber gaskets be customized for specific applications?
Yes, we offer custom manufacturing based on client specifications, including unique shapes, sizes, material compounds, and performance characteristics to meet exact requirements.
How do I maintain and inspect rubber gaskets?
Regularly inspect for signs of wear, cracking, compression set, or chemical degradation. Replace gaskets during routine maintenance schedules or if any damage is detected to prevent failures.
Are there eco-friendly or food-grade rubber gasket options?
Yes, materials like FDA-approved silicone and EPDM are available for food and beverage applications, ensuring compliance with safety and environmental regulations.
What is the difference between a gasket and an O-ring?
Gaskets are typically used for sealing flat or irregular surfaces, while O-rings are circular seals designed for radial or axial compression in dynamic or static applications, often in grooves.
How does temperature affect rubber gasket performance?
High temperatures can cause hardening, cracking, or loss of elasticity, while low temperatures may make the material brittle. Selecting a material with an appropriate temperature range is crucial for optimal performance.
