TracTuff billet radiator cap bungs are designed for use with my 3" and 4" billet tank lids; they match perfectly to the lids ID for a simple inside weld that you cant see once finished. On occasion, I have used them for odd projects, as long as there is a 1-1/2" hole.

I also offer the same two cap bungs with a 1-1/4" counter bore for easy locating on a 1-1/4" OD tube... just select the counter-bore version. 

NOTE: The domestic cap bung has a 1/8" NPT port and the import version has a 1/16" NPT for connection to an overflow. The domestic version uses any early model (late 70's Chevy C10 Pickup w/ 454) cap and the import version uses early model Honda (88'-91' Civic/ CRX and 90'-93' Integra) cap.
