New coupler on ISX compressor

[Waterloo]

I had one of these couplers on my radiator, factory from International, on my ProStar, along with the air compressor. I think I am going to purchase another one for my radiator with the corresponding female fitting to quickly drain my cooling system. I have a small electric pump that would work perfectly with this fitting using garden hose. I wound up removing that fitting on the radiator, as it was leaking.
