Rubber Gaskets and Seals

Coruba offers a wide variety of standard and custom-made rubber gaskets that are suitable for a diverse range of environments.

Known for their outstanding sealing properties and great resistance to wear and tear, rubber gaskets also have the unique ability of being able to withstand extreme pressure.

Bespoke Rubber Gaskets

Other key features of rubber gaskets include:

  • Excellent durability and flexibility
  • High impermeability to gases and vapours
  • Water and chemical resistance
  • Vibration and shock absorption
  • Stability in low and high temperatures

We can also manufacture rubber gaskets in different polymers such as:

  • Butyl
  • EPDM
  • Neoprene
  • Nitrile
  • SBR
  • Silicone
  • Vinyl
  • Viton®

Like most things, rubber gaskets change over time. To maintain their quality, you must follow certain storage guidelines.


What is the average shelf life of rubber gaskets?

The average shelf life will depend largely on the rubber material they are made of. Please find a general guideline in the table below:

  • Type of Rubber
  • Ethylene Propylene (EPDM)
  • Nitrile
  • Silicone
  • Neoprene
  • Flourocarbon
  • Epichloro-Hydrin
  • Halogenated Butyl
  • Approximate Shelf Life
  • 5-10 years
  • 3-5 years
  • 10-20 years
  • 5-10 years
  • 10-20 years
  • 5-10 years
  • 5-10 years


What factors contribute towards rubber gasket degradation?   

One or a combination of the following elements may affect your rubber gasket’s performance:

  • Heat
  • Humidity
  • Light
  • Oxygen
  • Ozone
  • Oils
  • Water
  • Acid


Where should I store my rubber gaskets?

Always store in a cool, dry place protected from moisture, heat, chemicals and direct sunlight. Rubber gaskets should be stored in areas that experience frequent temperature and humidity fluctuations; the recommended storage conditions are between 4 and 27 degrees Celsius, with 40 to 75 percent relative humidity in a room with no windows. Chemicals, dust and UV light should also be avoided.


How can I prolong their shelf-life?

Aside from proper storage conditions, here are some additional tips to prolong the life of your rubber gaskets:

  • Rubber gaskets should be stored in the original packaging to prevent deformation as well as size and grade mix-ups
  • To protect rubber gaskets from light, you can store them in a polyethylene bag inside a cardboard box; exposure to UV light, direct sunlight and fluorescent light can potentially cause the premature ageing of the compound
  • Store rubber gaskets in air tight containers to avoid exposing them to oxygen and the ozone. Exposure could cause them to crack, resulting in gasket failure
  • Inspect rubber gaskets for any damage before use to ensure their efficiency
