• Bleed kits with enough built-in compatibility for almost any hydraulic bleed job in the shop, regardless of brand. • Each kit comes with seals specific to the type of oil they’re intended to be used for (red = mineral oil/black = DOT Fluid). Using the wrong oil with the wrong kit will result in ruined seals and an inoperative bleed kit. • DOT Fluid kit ships with Avid/SRAM, Formula, Hayes and Hope adaptors. • Mineral Oil kit ships with Shimano, Magura, Tektro, Giant and Rockshox adaptors.
