OEM Replacement

Kloc Fabrication KFB-0326-001 Radiator Oil Cooler Fitting is an exact replacement for the OEM fitting and converts to 6AN.

This fitting uses a radial groove o-ring seal, and the o-ring is the primary sealing method. No sealant to be used on threads of fitting.

If you are installing in a GMT400 or Chevy 350, check out our full Oil Cooler Line Kit: GMT400/5.7L 350 Oil Cooler AN Line Kit – Kloc Fabrication

Above photos show the oil cooler removed from the GMT400 radiator. Please examine the fitting ports closely to determine if yours are the same. These are M20x1.5 thread, and use an o-ring to seal on the inside flat of the port.
