We HIGHLY recommend the maximum protection of your motor by using our exclusive Filtered Motor Gasket, part #MTR1500.

It is specially designed by our engineers to provide your motor with years of trouble free service by filtering out dust and dirt BEFORE they reach your motor and damaging it! The filtered motor gasket fits flush and is as easy to apply as a regular gasket and will not add any height to your motor during mounting!

For our standard motor gasket, see our part #MTR512.

Protect your motors from dust and dirt by using a motor filter. This prolongs the life of your motor and is a must for all motors. See our standard motor filter part #MTR553.
