G105 O-Rings ( 104.4 x 110.6 x 3.1 ) Japanese Industrial Standard JIS G105

104.4mm ID x 110.6mm OD x 3.1mm C/S

Japanese Industrial Standard JIS G105

 

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 Shore A is very stiff

 

Specs:

Polymers vary from 18% to 50% acrylonitrile content. Resistance to petroleum products increases as acrylonitrile increases; conversely, low temperature flexibility decreases.

 

Material:

NBR (Natural Rubber)

Standard Service Temperature: -40F - +250F

 

Application:

Petroleum Fluids, Water (to 212F), Silicon fluids, Ethylene Glycol, General Purpose
