O-rings
O-Rings are a very simple and cost effective sealing solution. Their versatility and reliability have made it the most frequently used type of seal worldwide.
O-rings are utilised within all kinds of applications from Static sealing ones in sub-zero temperatures to dynamic sealing applications in temperatures exceeding 300°C .
O-Rings have a simple design and it is because of this that they prove quite easy to produce by moulding. There are a vast range of standard dimensions available:
BS1806
DIN3771
Japanese (JIS)

Temperature ranges for standard materials
Nitrile -35°C - +110°C
Viton -20°C - +205°C
EPDM -55°C - +125°C
Silicone -55°C - +225°C
Please note that this information is only intended as a guideline, and individual material data sheets can determine the working temperatures of a specific material.
Standard material suitability
Nitrile - The most standard material, and for good reason. It is ideal to use with hydraulic oils, vegetable oils, animal fats, acetylene, alcohols, water, air, fuels and many other fluids.
-35°C - +110°C
Viton - Ideal for high-temperature applications and Viton also has every high resistance to various acids and bases. However, Viton is not ideal for hot water or steam and tends to lose its ability to work effectively in low-temperature environments.
-20°C - +205°C
EPDM - Ideal for outdoor use as this has a very good resistance to UV radiation and ageing. One of the more popular materials in certain industries for this reason.
-55°C - +125°C
Silicone - Silicone has a very good resistance to both low, and high temperatures. This makes it an ideal choice for various applications. They are also more flexible than their rubber counterparts.
-55°C - +225°C
