   Urethane Washers
 
 
Urethane Washers are available in Ether Polyurethane (the harder grade, shore A90) and Ester Polyurethane (shore A70 and the soft shore A50). You can choose from a wide range of standard sizes or pick a custom option with ability to specify all the dimensions in very fine increment.
