I need a 3/8" NPT to 3/4" hose end

[vegaschevy]

ANyone know who would carry oe of these? I can find 3/8-5/8 but I really ahve to tighten a 3/4" hose down to fit it on the 5/8" and it is a matter of time before it takes a crap!

Four Seasons part number 84780 is a straight fitting and part number 84777 is a 90* fitting--both are 3/4" hose to 3/8" NPT.

If you can't find one of these, you can always install a reducer in the hose from 3/4" to 5/8" then use the 5/8" hose to 3/8" NPT fitting. Obviously, this is not the most desireable method, but if it solves the problem....well, you know.

What application are you using it in ?

3/8NPT to 3/4 hose fitting isn't used much of anywhere.

I am pretty sure that is the size of my radiator thread to my heater hose. Ill take some measurements and let you know.

I know the threads is bigger then 3/8" but maybe I am off on the size a bit. I thought they were measuring inside hole on the NPT side.

Heater hose bibs are 1/2 npt thread and either 5/8 or 3/4 hose. You get get both of them at the parts store in the HELP section.
