Neoprene Oring

CR

Shore A Description:

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.

60 Shore A is softer than 70

70 Shore A is the standard

90 Short A is very stiff

Specs:

Compounds from neoprene exhibit fair oil resistance, good ozone and weather resistance.

Material:

CR (Neoprene)

Standard Service Temperature: -50°F - +275°F

Application:

Refrigerants (Freons), High Aniline Point Oils, Weather and Ozone, Ammonia Gas, Silicate Esters

Due to the excellent resistance to refrigerants such as Freon, neoprene compounds are used in refrigeration systems.

Not Compatible With: Phosphate Esters, Ketones, Brake Fluids
