Thanks Rodney. I picked up a couple more fittings to try out. I noticed that on my grove break caliper, Grove uses a fitting that has a Rust colored thread lock or something. The Hydraulic shop near my work couldn't advise as to what it was. They were offering me some Permatex brand thread Lock I assumed, it was the same substance as is stated on the Loc Tite 567 "methacrylate". It was either a Red or a Blue color. I assumed it was a Loc Tite like product. I will try this Loc Tite 567 vs having the unknown rust colored stuff.
