TUV ISO 9001:2008, ISO/TS16949:2009, ISO14001:2004, DIN3771, JIS B2401, GB 245201 and other standard.
Nitrile (or NBR) O-Rings are most commonly available and are cost effective. Ideal for use as seals on pumps, drive belts, and other general engineering applications.
NBR is good for applications that need to withstand fats, Greases and high temperature (+70°C). Temperature Range -30°C to +120°C (avoid prolonged use at higher extremes)
1. Suitable for: Many hydrocarbons, fats, oils gasoline, petroleum based hydralic fluid etc
2. Generally atacked by: Ozone, esters, retones, aldehydes, chlorinated and nitro hydrocarbons
3. For automotive applications requiring contact with petrol or diesel you may wish to consider Polymax Viton o ring kits
It is a kind of spare parts which are often applied to seal the oil, the other name of oil seal is swivel bearing lip-type packing. As we know that there is some oil would go-in the rubbing parts of the machine usually and in order to resistant against this oil we need to use the oil seal to seal the gap of the machine. More than that, we have to concern to how to seal the water, chemical liquid and the dust, all of these environment calls for the oil seal. Most oil seals work with 20~50? , but some can sustain higher temperature such as: NBR(-40~120? ), ACM(-30~180? ), VITON(-25~300? ).
1. Materials in NBR, EPDM, SBR, SR.
2. outside diameter from 6 to 1,200mm
3. All kinds of types
4. Various colors
1. Ozone and chemical resistance
2. High temperature resistance
3. Oil resistance
Oil seals come in a variety of shapes and sizes. They are often referred to as gaskets, o-rings, packing, or swivel seals and can be made of such things as rubber, cork, composites, and even leather. Nonetheless, they are all made to do one thing, to ensure that the oil used by a machine has been sealed inside to keep it from leaking out, which could otherwise cause mechanical failure. Commercialized types of oil seals need to be pressed on using hydraulics or specialized tools, but common do-it-yourself o-rings and gaskets can be installed using the same basic techniques.
NBR, FFKM, VMQ, PTFE, PU and so on (according to your requirements).
1. Simple, reliable design
2. High sealing effect against dirt, dust, water and abrasive media from the outside and against oil and grease from the inside
4. Long service life
5. Self-centering to compensate for shaft eccentricity or misalignment
7. Easy to assemble

The most important component of an oil seal is the clastomer material.
To consider the environmental conditions, the following properties are important:
1. Good chemical resistance
2. Good resistance to heat and low temperature
3. Good resistance to ozone and weather aging
4. Good elasticity
5. High resistance to water
6. Low compression set
7. Raw material cost
