The very high wet boiling point (421F) superior to conventional DOT 5.1 non silicone base fluid (356F min) and DOT 4 (311F min) assures efficient braking even under humid and moist conditions. Indeed, DOT 3, DOT 4, and DOT 5.1 brake fluids have the property to absorb humidity in the air, which reduces their boiling points and increases the risk of boiling the fluid. RBF 600 Super Hi-Temp racing brake fluid was developed for high heat and the extreme pressure demands of professional racing. RBF 600 has a low viscosity blended with unmatched performance in the most extreme conditions for minimal hydroscopic effect and very low compressibility. The RBF 600 will give solid pedal feel, great response, super high heat protection and maximum life.
The RBF 600 container is filled with Nitrogen to increase shelf life and eliminate contamination while factory sealed.
This isn't some cheap brass fitting, but a high quality, durable stainless steel part. It's used to add an oil feed line (for an oil pressure gauge or a turbo) on an engine that has a BSPT style thread for the stock oil pressure sender unit. Motors in the 1999+ Mazda Protege use a BSPT style thread, making this the ideal solution for an oil feed line in a Protege.
