I own a home brew shop so I get to see most of the things that can go wrong and have looked into those red plastic pinlock fittings.
Coke in Australia had the 2/3 pin fittings made to their speck, they came into postmix relatively late and didnt wast customers using other peoples product in coke equipment, so they came up with a unique design.
The pinlock from OS is a different standard; the red plastic fittings are made by Cornelius and will not fit Ozy gear.
Any HBS should be able to order you a new gas or liquid ball-lock post, I have accumulated a few 2nd hand pinlock posts this way, but 2nd hand ball-lock posts are rare as hens teeth, I think you are stuck with the red connectors, I got a couple u can add to your collection, real cheap if you want them.
