Buna 70 Orings

Buna-N Nitrile O-rings 70 Durometer are heat resistant up to 212*F and 250*F intermittent to -30*F. 

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound.  70-durometer hardness should be used whenever possible as it offers the best combination of properties for most O-Rings applications. Softer compounds stretch easier and seal better on rough surfaces.  Harder compounds offer greater abrasion resistance and resistance to extrusion.  Extrusion must always be considered where high pressure is used.   

Typically used in applications with propane,butane,petroleum oil, mineral oil, grease, diesel fuel, mineral oils/greases, diluted acids, alkali and salt solutions at low temps and water.

NOT COMPATIBLE WITH....Gasoline, benzene, trichlorethylene, ketone, acetone, acetic acid, ethylenester, strong acids, brake fluid with glycol base
