Oil Tight Hole Seals

Application

FabTech Hole Seals are used to seal unused push button holes, conduit and knockout holes and other openings of irregular shapes and size against dust, dirt, water and oil. They will cover holes ranging in sizes from .19″ through 4.00″, and can be used on enclosures having a wall thickness up to .31″.

Design

An Oil Tight Hole Seal has a cover with a 1/16″ flange formed around the perimeter and a #10 x 5/8 stud welded in the center. A gasket is placed over the stud and these two parts are usually positioned on the outside of the enclosure. A backplate and wing nut are fastened to the Seal from the inside of the enclosure. As the wing nut is tightened, the cover compresses the gasket and seals the hole.

ALL FabTech Supply Oil Tight Hole Seals are UL Approved.
