TEK Nozzle Holder with Hoses SM-Modellbau # 2785

Suitable holder for our TEK nozzles.

The aluminum TEK nozzle holder is permanently glued into the aircraft. For this purpose, a 4 mm diameter hole is drilled in the vertical stabilizer or fuselage at the desired location. If there isn't enough wall thickness there, a piece of plywood must first be used to build up the area to ensure the holder can be glued firmly enough. The TEK nozzle is relatively long, so you have a fairly large lever. The nozzle holder is slightly thicker at one end. This side accommodates 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 usually simply inserted into the thinner side of the nozzle holder. It clamps there and is sufficiently sealed. The insertion depth is 10 mm. This saves you the trouble of having to install the hose afterwards during subsequent installation, 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 stretched a little over a short section. If you then cut it again in this area, it will be slightly 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 precise as possible in the direction of flight, and for fuselage mounting, perpendicular to the direction of flight. The aluminum tube should protrude outwards by about 3 mm so that the silicone hose for sealing can be attached here. On the GPS Logger 2, a piece of silicone hose is attached to the TEK connection as a transition to the Teflon hose.
