O-ring - EPDM

EPDM (Ethylene Propylene Diene Rubber) is a synthetic rubber elastomer which can be cross linked with sulphur or peroxide cured.

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
• Can be used both for static and dynamic applications
• Both for rod and piston applications
• Wide compound range
• Wide range of dimensions
• Easy installation and removal
• Excellent resistance to heat, water, ozone, ageing and weathering
• Good resistance to steam and polar substances

APPLICATION
Used in almost in every industry but especially in non-moving machinery and in static sealing applications, e.g. as flange or cover seals.
EPDM O-rings are known for good application with hot water and brake fluids (based on glycol). EPDM O-rings must not be used for mineral oil, grease and fuels. EPDM has excellent electrical insulation properties. Good mechanical attributes and good ozone, ageing and weathering resistance.

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 lubricated. Be sure not to use a lubricant that will cause deterioration of the seal.
Tolerances: DIN 3771 / ISO 3601
