Aero Metal Flanges

Flanges to suit Aero Metal centres.  5 types available as follows:-

Standard Flange
Surface mount bolt-on supplied with metric socket screws.

Glass In
To build into a composite skin. The flange is machined down on a taper so it is always below the curved wing surface.  We suggest drilling lots of large holes in the flange so it bonds into the composite structure, and avoids adhesive delamination around the filler hole.

Threaded
Built for the Glastar but now widely used to thread into a tank and screw down "flush" to the skin.  Ideal for wooden aeroplanes avoiding recesses and doors eg for the Falco. The 2-5/16" thread conveniently fits a 2.25" hose, and the flange can be retained to a skin by our special back nut, still leaving room for a hose.

Cirrus
A low profile threaded flange is designed for Cirrus so as to enable the cap to be fitted after the wing is painted- avoiding damage, dirt, masking, filling and other nuisances.  The same part can be glued in place – just a wipe of "pro-seal" – place in position, and the job is done.

Vans
Special flange machined to fit the wing profile, and rivet inside the tank.  This means it can only be fitted when the builder makes the tank as fastbuild wings come with the Vans cap fitted.
