Looking for Help to ID a Stant Cap

Recommended Posts

I have no idea what this is off of.  I've tried searching the Stant part number of 2465 with no luck.  It has a patent date of 10-2-23. The perspective with the ruler didn't quite turn out the way that I thought it would but the cap has an outside diameter of about 4 inches and you twist the top to unlock it.  I just noticed the set screw to lock it on once it has been threaded to what ever it is that it fits.  This was a piece my father picked up at Hershey a couple of years ago.  Any help is appreciated.

Please list the thread diameter and pitch. Stant made a similar cap to fit many cars and sold as aftermarket as well, it’s what car has that internal thread that will answer your question.

I will get the diameter tomorrow, but you'll have to help me out by what you mean by the pitch?  It's just not a term that I'm familiar with

Ok thank you, that's a term that I do know - just learned something!

I’m glad I taught you that terminology, TPI wasn’t commonly used in the trade school I attended... funny how some things that get bashed through the thick skull of a teenager sticks forever!

 

Its easy if you have a pitch gauge...

Story of my life, a day late and a dollar short - I had every intention of getting those measurements yesterday and then again today while I was at the shop, even though about it too while I messing around with something else and just got home and remembered what I forgot to do!

That  is a nice looking gauge.  Don't let it rust away. 


It came from a yard sale last summer for $2.00 and I haven’t cleaned it up yet other than some WD40, I should dig out some steel wool now you mentioned it...

 

I will say it’s the most comprehensive pitch gauge I’ve seen, inch series only but I can do the math for metric pitches when needed.

if you have a tap and die set you probably have a gauge.

Thank you to both of you again and now I have the measurements of the diameter being 2.25 inches and the pitch is 18.  I don't have a gauge near as nice as the one shown above but it now justifies keeping this tap and die set handy on the bench

Well, I can’t help with the ID, but I will say it’s a rather large thread for an internally threaded radiator neck. The mid 20’s Pierce-Arrow is around 2” and a similar age Cadillac is the same as I’ve been told. Those are pretty big cars but there’s obviously a bigger one somewhere...

 

Good luck with your search, at that size it should narrow the field a lot!
