TracTuff Radiator Cap Bung

TracTuff Radiator Cap Bung

$29.95

TracTuff billet radiator cap bung is used with our 3" or 4" billet tank lids and matched them perfectly for an inside weld but you can use it to fabricate anything that has a 1-1/2" hole or a 1-3/8" counter bore.

The cap bung has a 1/8" NPT port for connection to an overflow and uses any early model domestic cap. We recommend Stant part number 10230 (16 psi) standard cap or 10392 (25 psi) racing cap or you can cross those part numbers to a wide range of other offerings.
