Gasket Supply Co. only uses premium grade Nitrile (NBR), Buna-N Rubber that meets RMA Class 1 oil resistance requirements when cutting gaskets or selling bulk sheet material.
CAUTION: Many gasket suppliers and cutting houses use a commercial grade by default, which commonly has only a moderate oil resistance.
WARNING: WITH MANY DIFFERENT COMPOUNDS AVAILABLE, NITRILE RUBBERS’ OIL RESISTANT PROPERTIES CAN VARY SIGNIFICANTLY. THIS CAN AFFECT THE PERFORMANCE AND SERVICE LIFE OF YOUR GASKET WHILE INCREASING THE CHANCE FOR COSTLY DOWN TIME OR SEALING FAILURE. IT IS IMPORTANT TO CONSIDER THE PROPER MATERIAL GRADE WHEN REQUESTING A QUOTE OR USING AS A SPEC FOR A JOB. THIS WILL SAVE COSTLY JOB SPECIFICATION ERRORS AND DOWN TIMES.
