4 Row radiator install, small problem, help needed.

[Seosamh]

Hello all.
I'm looking for a source or part number for what I believe is a 1/2" UNF male x 1/2" SPT female adapter. Looked on line for hours with no proper result. I don't want to take the easy way by cutting off the oem threaded end fitting. Maybe I'm using the wrong key words in my search for the end that requires an O-ring. Any reply would be greatly appreciated, Thanks.

he Fitting in the photo is what the Radiator came with, the opposite end of it is the quick release type.

There's a lot going on there...

a British pipe thread (BSPP, UNF, and other o-ring pipe threads) are always o-ringed on the flange, not in inside mating surface.

And that fitting that came with the radiator looks like it has the same geometry of a flared brake line. I spent some time on McMaster trying to find that style fitting with an o-ring on the inside and nothing is showing anything resembling that fitting. The only thing it looks like is a large double flared 45 degree fitting (Brake line) that they stuffed an o-ring in for some reason.

And lastly, does that radiator come with a good return policy? If so, please consider using it before it expires. There are multiple things going on in your pics and it being 4-core aluminum that makes it a wallet-lightening marketing display piece. There are much better options out there.

4 Core? You live in Death Valley? Lol

 

[RichLo]

4-core aluminum isnt needed unless its 6" thick. 4-Core was only needed back in the brass radiator days. Brass would burst after 5/8" wide cores, Aluminum can handle 1.5" easily. More cores equals more turbulence which means more resistance and less cooling efficiency.

... only one of the reasons I would highly recommend return it ASAP.

After looking over your post again, I almost bet that adaptor that came with the radiator is a 45 degree flared compression fitting to Ny-Lock push-lock adaptor. Nobody ever uses push-lock for engine oil or trans oil for very obvious reasons.

Isn't that the same style of fitting as used on GM PS gears and GM fuel plumbing? Perhaps not the same size--although it might be.

Similar to the O-ring end of THIS:

You'd need the O-ring end with the right threads and O-ring size, and the female end able to accept an inverse flare of the correct thread size and tubing diameter.





As said, a "4-row" aluminum radiator is just silly.

Thanks for your help. I was getting ready to weld a 1/2" 20 female fitting to the adapter in the photo when I realized the adapter it came with is two piece. I unthreaded the quick release part and now all that is needed is common 1/2" 20 NPT female x 5/8" male adapter. Embarrassing that I didn't notice this sooner rather than wasting everyone's time here in the forum.
