Oscar is right. Be careful about what you put in your brake systems. Locally, we're lucky to have a local supplier of hydraulic fittings who is also a pilot. He is very careful about what he sells, and is very knowledgeable. His O rings meet aviation specs for brakes.
Many pilots go to him and buy O rings, and there's never been a problem. The price is 1/4 or less than ACS, and it's quicker.
