PRO-TEK AIR CLEANER NUT WITH RUBBER SEAL - AF-3001

The Pro-Tek Air Cleaner Nut with Rubber Seal helps seal out dirt and debris from entering the motor around the stud in the air cleaner top. This air cleaner nut has a 3.5” diameter rugged rubber boot around the nut and works best with air cleaner tops that have a 3/4” or deeper nut pocket or a larger opening requiring a large washer or flange. The actual nut is a steel cap nut with a 1/2” hex threaded for either a 1/4”-20 or 5/16”-18 stud.
