Air line safety fitting

Often when running new air lines in your rig, whether for an air ride seat or an air horn, you have to pass through sheet metal panels. If done poorly it can lead to chafing and create air leaks in your system which is likely shared with your air brakes.  These DOT approved push-to-connect fittings can be installed in an oversized hole and screwed to the adjacent panel to prevent any tube damage and create a clean sealed install.
