What differences between different rectangular o rings?

1. Viton square rubber rings

Material: Viton/ FKM / FPM

Hardness: 0~90A

Temperature: -20~+260°C

Medium: water, oil, dust, air.

Features: Viton/FKM o ring shows excellent heat resisitance and chemical resisitance, low compression set,

and excellent aging characteristics.

Applications: Viton rectangular rings are widely used in environments that require high precision, high temperature

resistance, high wear resistance, Such as automotive, electronic, aerospace, Marine.It's not generally

recommended for exposure to hot water, steam, polar solvents, low molecular weight esters and ethers,

glycol based brake fluids, or hot hydrofluoric.

2. NBR/Nitrile square rubber rings

Material: NBR/ Buna-N/ Nitrile

Hardness:30~90A

Temperature: -30~+110°C

Medium: water, oil, dust, air.

Features: NBR/Nitrile  ring shows excellent compression set, tear,and abrasion resistance.

Applications: NBR/Nitrile O ring are widely used in cylindrical surface static sealing,flat face, static sealing,  

vacuum flange sealing, triangle groove application, pneumatic dynamic sealing ,etc.

3. Silicone square rubber rings

Material:Silicone/ VMQ / PVMQ

Hardness: 20~90A

Temperature: -60~+300°C

Medium: water, oil, dust, air.

Features: Silicone/VMQ/PVMQ square o rings provide excellent resistance to ozone, oxygen, and moisture. Low

physical strength and abrasion resistance combined with high friction properties limit silicone to static seal

applications.

Applications: Silicone rectangular o ring are widely used in foodstuff and cryogenic engineering.

Advantage of rubber rings from our company:

Our company has own factory,which has professional machine as below:Rubber-internal mixer, open mill, edge trimming machine, Automatic slitting machine, Automatic slitting machine for Silicone, Vacuum vulcanizing machine, Hydraulic vulcanizing machine, Deflashing machine, lapping machine, oven, etc.If any new machine came out,we will place order for them.Because excellent machine will improve our productions capacity.And the old one will be sold out as a cheap price.

The way for assure quality is need advanced testing tools:Manual hardness tester, Hydraulic hardness tester, Aging tester, Thermostatic oil bath, Cutter press machine, Tensile testing machine, Moving die rheometer, Densimeter, Vision measuring machine, Vemier caliper, Tape measure. Our QC team is not only inspect finished square rings but also test samples in all procedure.It can solve problems in the first time by this way.
