I gotta give a shout out for this stuff. it sealed a temp sender into the intake that Indian head would not seal (tho it is pipe threads and in all fairness pipe dope may have sealed it but I was out) but the sender into the adapter ain't NPT and the stat housing that would not seal after multiple attempts (including drawfiling it flat (& a new one from NAPA) & on that it even took TRS gasket maker PLUS the gasket! On a side note the NAPA housing has a straight flange/no barb on the end like the OE Mopar one, I highly suggest filing a wide groove in it (I got a hot antifreeze bath in the middle of this ordeal!). All good (in the hood) now
