Air Hose Wall Pass-Through Trumpet
This screw-on grommet fits a 1-1/2 in (38.1 mm) hole-saw hole. It lets an air line, shop-vac hose or extension cord pass through a garage wall or into a compressor closet without the hose rubbing on raw drywall or stud edges. The part has a 76 mm flange with three countersunk #8/M4 screw holes (4.5 mm) and a 28 mm bore that flares at 45° to 40 mm on the room side. A 25 mm crush-ribbed sleeve press-fits the hole.
