O-ring – Viton® Extreme-ETP

Viton® is a registered trademark of DuPont Performance Elastomers.

O-rings are the most common sealing element, and because they are cheap and simple, the area for application of O-rings is very wide in hydraulic and pneumatic systems. Where working conditions and equipment are suitable, they can be used both in static and dynamic applications, but they are not recommended for rotary movements.
Because they take up less space and provide two-sided sealing compared with other sealing elements, O-rings make designing easier. Obtaining good results from O-ring applications depends on suitable measurements, choosing correct materials, and suitable surface quality on metal parts.

PROFILE
 
 
PRODUCT ADVANTAGES
• Good resistance to hot water and vapour
• Excellent chemical resistance
• Outstanding mechanical values
• Good physical properties
• Excellent resistance to acids and alkaline solutions
• Excellent resistance to complex solvent mixtures
• Excellent resistance to additive containing amines
• Excellent resistance to corrosion inhibitors

APPLICATION
Fluorinated rubber’s excellent resistance to chemicals is exceeded by that of Viton® Extreme-ETP. Due to its modified polymer structure, swelling in solvents and highly basic media is significantly reduced. What’s more, Viton® Extreme-ETP possesses outstanding mechanical values and good physical properties.

INSTALLATION
O-rings are fitted into the groove by hand. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation all individual parts of the seal must be oiled with system oil.
Tolerances: DIN 3771 / ISO 3601.
