These are the COG caps we are using on our new Seven SIns Choppers oil tanks (Coming Soon). This assembly includes a weldable (1/2" height ) bung in your choice of steel or aluminum. A convenient stepped shoulder is machined in the base of the bung,
acting as a positioning locator during fabrication. The lightweight, 1-5/8" diameter non-vented cap features machine-cog style notches
that is super easy to grip. The 6061 billet aluminum cap is precision
machined and comes with a sealing
rubber o-ring. Made In USA.
