Kinugawa Turbo Oil Pan Return/Drain Plug Adapter Fitting 10AN No Welding Steel

Got this to install on a cast aluminum oil pan.The bolt threads (pan side) are M18 x 1.5mm. Instead of just drilling a hole and tossing it on there, I tapped it to create an even better seal.Make sure to use LocTite on the nut.

So far no leaks.I did thread lock it just to be on the safe side. Does come with a rubber gasket for both inside and outside of the oil pan

Super well made bulkhead fitting I use them for valve covers and turbo oil returns .
