Hong Yeng water fitting size and thread.

Make sure that those connectors will work well with silicone hose which is needed because it may come into contact with those stainless tubes which are very hot during operation. Other kinds of plastic hoses may melt.

The threads are 1/8 M10x1 metric. Don't even think about using those computer fittings. Even if you could match the thread size, they won't handle the pressure involved.

Sorry, I misunderstood the question. The threads for the coolant spigots are 1/8 BSPP.


Thanks guys. I'll be using threaded and barbed males on the compressor side and barbed females on the bucket side. I think the silicon hoses should work on the barbs.
 
Ok guys quick update. Found the right fittings and it’s tits! Bucket stays outside in the carport while the compressor gets locked in the storeroom for safekeeping. 

little pricey but worth it to me for a no mess quick disconnect.
