EPR is a great material to be used in many different fields, especially when it comes to commercial aircraft. It offers great ozone, water, steam, acid, and base resistance. However, it lacks in petroleum sealing. Temperature ranges -65ºF to 300ºF. Ethylene Propylene carries a special resistance to Skydrol® fluids whic Read More.

Aflas® is unique compared to other rubber materials as it has a wide range of resistive properties. Such as high temperatures, chemicals, electrical, and petroleum. This being said you can easily apply this to many factors such as down holes, general steam, marine engines, and mechanical seals. Aflas® performs well in Read More.

O-Rings and other elastomers should be stored at a proper temperature that should NEVER exceed 120ºF but is recommended to stay below 100ºF at all times. Any heat sources such as furnaces, fires, boilers sunlight, and radiators should not be near any elastomer. Read More.

Nitrile (Buna-N) is the most widely used general-purpose O-Ring elastomer. Because of the resistance to petroleum and oil products, superior compression set, tear, and abrasion resistance. However, it does not wear very well in sunlight or ozone Nitrile isn’t known to have the greatest chemical resistance but is known Read More.

Backup rings are commonly installed with O-Rings to improve their performance. Backup rings are useful for many different reasons but the main reason is by blocking or reducing the extrusion gap. This prevents the O-Ring inside to be damaged or extruded causing failure of some systems, especially in high-pressure situa Read More.

Polytetrafluoroethylene, better known as PTFE, is a material founded by E.I. DuPont in 1938 has become a widely popular choice of material when sealing a wide range of chemicals, acids, bases, and steam. This super tough material is cannot be compressed very easily, which is good for abrasion resistance but bad for pro Read More.

The durometer is a measurement of the hardness of a piece of rubber. However, there are a few different scales the industry uses to measure the durometer of an object. The most popular way is the Shore A durometer scale. Shore A is the way APG measures its materials to ensure the most accurate hardness rating possible. Read More.
