Design Rubber Gaskets Suggestion

When designing custom rubber gaskets, balance seal geometry, compression, and material choice. Ensure even compression to avoid stress points. Choose rubber hardness and resistance to chemicals, heat, oil, and UV based on the environment. Optimize groove size and surface finish to prevent leaks. Use multi-lip or O-ring features for dynamic or high-pressure sealing, and ensure tight tolerances for a reliable, long-lasting fit.

Rubber Gasket Processing Methods

Material

Our rubber seal gaskets are available in a wide range of materials based on performance needs:

  • Nitrile Rubber – Oil resistance
  • Silicone Rubber –
  • Temperature stability
  • EPDM – UV and weather resistance
  • Neoprene – Versatile general-purpose use
  • Fluorocarbon – Chemical and heat resistance
  • Natural Rubber – High flexibility

Rubber seal gaskets are critical for maintaining secure, reliable seals across countless systems.

  • Excellent fluid and gas sealing
  • Resistance to pressure, temperature, and chemicals
  • Absorption of vibration and mechanical shock
  • Noise reduction
  • Easy installation and replacement

Rubber gaskets are widely used in sealing and cushioning across various mechanical systems.

  • Pipe flange sealing
  • Pumps and valves
  • Electrical enclosures
  • Engines and HVAC units
  • Lids, doors, and access panels
  • Water, oil, and gas containment systems

It depends on the environment—NBR is best for oil, EPDM for outdoor/weather, and FKM for chemicals or high heat.
Typically 20–30% compression is ideal for effective sealing without over-stressing the gasket.
In most cases, no. Once compressed or chemically aged, gaskets lose effectiveness and should be replaced.
Yes, we offer FDA-approved silicone and EPDM gaskets suitable for food, beverage, or medical applications.
Absolutely. We support custom cutting and molding for oversized or complex gasket geometries.
