Setrab cooler fitting question
 

So I purchased a Setrab oil cooler at racerpartswholesale and after installing it and installing the fittings, I was doing research and noticed that Setrab says it needs m22x1.5 fittings. They sold me 1/2BSP fittings with it instead...I already put the fittings in it, I hope its not all stripped. What would you guys do?
The sell the correct fittings with the cooler in their own website Setrab Oil Coolers - Setrab 13 Row Oil Cooler - Series 6

The guy told me it needed BSP fittings...should I try it?

Its right here in their website...Setrab Oil Coolers - Setrab Oil Cooler Fitting 22mm Male x AN Male

I took the fittings off and the cooler threads look fine. Glad I didn't tighten them too hard and used teflon tape

BSP on the sandwich plate, m22 on the oil cooler.

I took the fittings off, no noticeable thread damage, thank god

I went to racerpart wholesale and they gave me a set of m22x1.5-10an fittings for free, no questions asked.
