Product Details
FKM O Rings offer many benefit to designers,engineers,maintenance staff and plant operators, they suit many static and dynamic application, very compact and occupy little space, seal efficiently in both directions, can work between -65℃ and +300℃.
Product Details
O-Ring, the cutting edge is a "O" shape, which is the most common, classic, economical and useful sealing type in both dynamic and static application.
To understand a basic idea of O-Ring, it is essential you should know:
● The O-Ring dimension formula is very simple, OD = ID + 2*CS
● The popular O-Ring standards are formulated by its location and country
● The O-Ring tolerance has its limitation, when the size is out of tolerance; it means failure will cause leakage.
● O-Rings are made of elastomers which are with resilience or memory sufficient to return to its original shape after a major or minor distortion.
Oil And Heat Resistance Comparison Chart
Fluorocarbon rubber has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. It has higher resistance to swell in high octane and oxygenated fuel blends.
Low temperature resistance is normally not favorable and for static applications is limited, although in certain situations it is suitable down to -40°F (-40°C). Gas permeability is very low and similar to that of butyl rubber. Special fluorocarbon compounds exhibit an improved resistance to acids, fuels, water and steam.
