149 www.BMRS.net Technical Information 1. Cut the aluminum tube square and deburr the inside and outside diameters (not excessively). 2. Assemble fitting by sliding the sleeve and nut over the tubing. 3. Flare the tube with the appropriate proprietary flaring tool. After flaring, the tube end should conform to the figure and table below. It is important not to over tighten hose fittings to their mating adapters or housings. Over tightening causes permanent deformation of the fitting seat and will result in the mating adapter sealing face being made concave, this will inhibit repeated reliable use of both the fitting and the adapter.
