O-ring - FKM

FKM (Fluorocarbon Rubber), also known as Viton®. FKM is fluorocarbon rubber according to DIN/ISO norm and FKM is fluorocarbon rubber according to the American standard ASTM. Viton® is the registered trade mark 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
• Can be used both for hydraulic and pneumatic systems
• 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
• Good resistance to mineral oils, greases, synthetic oils and mechanical wear
• Excellent resistance to heat, ozone, ageing and weathering

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.
FKM O-rings are known for their resistance to chemicals and heat. They have outstanding resistance to minerals oils, aliphatic and aromatic hydrocarbons. 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 oiled with system oil.
Tolerances: DIN 3771 / ISO 3601
