Gasket Supply 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.

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.
