Mounting bracket for our TEK nozzles

The aluminum TEK nozzle mount is permanently glued into the aircraft. To do this, drill a 4 mm diameter hole in the vertical stabilizer or fuselage at the desired location. If the wall thickness is insufficient at that point, you must first reinforce the area with a piece of plywood to ensure the mount can be glued securely. The TEK nozzle is relatively long, so you have quite a lot of leverage.

The nozzle mount is slightly thicker at one end. This side accommodates the TEK nozzle. Please pay attention to the installation direction.
The nozzle mount is designed so that the nozzle fits snugly and seals well even without a silicone tube. The nozzle is inserted 20 mm into the mount.

The Teflon tubing is normally simply inserted into the thinner side of the nozzle holder. It fits snugly there and provides a sufficient seal. The insertion depth is 10 mm. When retrofitting, this saves you the trouble of having to install the tubing later, as it would otherwise not fit through the hole in the tail section.
If the tubing is slightly too thick (tolerance), it can simply be stretched out a bit over a short section. If you then trim it again in this area, it will be slightly thinner and should fit.

The bracket is then cleaned, roughened slightly if necessary, and bonded with epoxy (e.g., Endfest 300). The alignment should be as precisely as possible in the direction of flight; when mounted on the fuselage, it should be perpendicular to the direction of flight. The aluminum tube should protrude about 3 mm outward so that the silicone tubing can be attached here for sealing.

On the GPS Logger 2/3 or MicroVario, a piece of silicone tubing is attached to the TEK connector as an adapter to the Teflon tubing.
