Fitting holder for our TEK nozzles.
The TEK nozzle holder made of aluminium is glued firmly into the aircraft. To do this, drill a 4 mm diameter hole in the rudder or fuselage at the desired location. If there is not enough wall thickness, a piece of plywood must first be used to fill the hole, so that the holder can be glued tightly enough. The TEK nozzle is relatively long, so you have quite a lot of leverage.
The nozzle holder is slightly thicker at one end. This side accommodates the TEK nozzle. Please pay attention to the direction of installation. The nozzle holder is designed in such a way that the nozzle clamps a little and seals well even without a silicone hose. The nozzle is inserted 20 mm into the holder.
The Teflon hose is normally simply inserted into the thinner side of the nozzle holder. It clamps there and is sufficiently tight. The insertion depth is 10 mm. In case of subsequent installation, this saves the problems of having to mount the hose afterwards, because otherwise it would not fit through the hole in the tail unit. If the hose is a little too thick (tolerance), it can simply be lengthened over a short section. If you then cut it again in this area, it will be a little thinner and should fit.
The holder is then cleaned, possibly roughened a little and glued with epoxy (e.g. Endfest 300). The alignment should be as exact as possible in the direction of flight; when mounting on the fuselage, it should be at right angles to the direction of flight. The aluminium tube should protrude about 3 mm to the outside so that the silicone tube can be attached here for sealing.
On the GPS-Logger 2/3 or MicroVario, a piece of silicone hose is attached to the TEK connection as a transition to the Teflon hose.
