Like most things, rubber gaskets change over time. To maintain their quality, you must follow certain storage guidelines.
Here are some important rubber gasket maintenance questions and answers:
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 |
Approximate Shelf Life |
Ethylene Propylene (EPDM) |
5-10 years |
Nitrile |
3-5 years |
Silicone |
10-20 years |
Neoprene |
5-10 years |
Flourocarbon |
10-20 years |
Epichloro-Hydrin |
5-10 years |
Halogenated Butyl |
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
