Unisens Nozzle holder with hoses

The TEK aluminum nozzle holder is firmly glued into the aircraft. To do this, drill a 4 mm diameter hole in the vertical stabilizer 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 firmly enough. The TEK nozzle is relatively long, so you have quite a large lever.

The nozzle holder is slightly thicker at one end. This side holds the TEK nozzle. So please pay attention to the installation direction.

The nozzle holder is designed so that the nozzle clamps slightly 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. When retrofitting, this avoids the problem of having to fit the hose later, as it would otherwise not fit through the hole in the tail unit.

If the hose is a little too thick (tolerance), it can simply be lengthened slightly on a short section. If you then cut it again in this area, it will be slightly thinner and should fit.

The bracket is then cleaned, roughened if necessary and glued with epoxy (e.g. Endfest 300). The alignment should be as exact as possible in the direction of flight and, when mounting on the fuselage, at right angles to the direction of flight. The aluminum tube should protrude outwards by about 3 mm so that the silicone tube can be attached here for sealing.

On the GPS-Logger 2/3 or MicroVario, a piece of silicone tube is attached to the TEK connection as a transition to the Teflon tube.
