NBR FKM Rubber O Rings

Rubber seal O Ring EPDM NBR FKM Silicone natural rubber seal ring OEM ODM factory customize SGS Machinery Seal

Nitrile (Buna-N) O-Rings
Buna or nitrile O-rings are the most common O-rings used throughout the fittings industry and are considered the standard at OmegaOne. These rings serve a wide range of temperatures from 40 below zero to 250 degrees Fahrenheit. They’re also known for their performance in the petroleum and fuel industry, and many military specifications require these O-rings. Thanks to their permeability for oil and gas, these O-rings are most commonly used in the compressed natural gas applications.

Fluorocarbon (Viton) O-Rings
Viton O-rings are the next most common ring which can handle temperatures ranging from 15 below zero to 440 degrees Fahrenheit. These rings perform well in high-temperature environments, oxygen oils, hydraulic fluid, and chemical fuel applications. 90-durometer for standard applications, and 75 durometer for CNG applications.

silicone o-ring

for machinery car seals are one of the most common seals used in machine design,it can be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring.

Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.

It has the advantages

1. inexpensive;

2. Small installation space;

3. easy to make,easy to install;

4. stable performance;

Applications :
NBR/Silicone/FKM/EPDM O Ring is often used in the working environment that needs to resist of heat, chemical corrosion, oil, etc.
The o rings are widely used in metallurgy, chemical, automobile, mechanical and electric power industry.
The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.
