Can you explore ways to adapt a small Teflon tube to a similar sized silicone tube that exhibits good sealing properties? The size of these tubes are very small, on the order of 1mm. We would like to avoid glue or small screws.

Adapting a small Teflon tube to a silicone tube without using glue or small screws can be challenging due to the small size and the need for a secure seal. However, there are a few potential solutions you can explore:

Heat shrink tubing: You can try using heat shrink tubing made of silicone material. Cut a piece of heat shrink tubing slightly longer than the area where the two tubes will connect. Slip the heat shrink tubing over one end of the Teflon tube, then slide it over the silicone tube as well, covering the joint. Apply heat using a heat gun or a similar heat source to shrink the tubing and create a tight seal.

Compression fitting: Consider using a compression fitting designed for small tubing. Compression fittings typically consist of a threaded nut and a ferrule. Place the ferrule over the Teflon tube, insert the tube into the silicone tube, and thread the nut onto the silicone tube. Tighten the nut until it compresses the ferrule against the tubes, creating a tight seal. Compression fittings can be found in various sizes, so you'll need to ensure you get one suitable for your small tubes.

Mechanical clamping: If the tubes have some flexibility, you can explore using small stainless steel or plastic clamps to secure the tubes together. These clamps typically have a screw or a snap mechanism that allows for a tight and secure connection. Ensure the clamps you choose are appropriate for the size and material of your tubes.

Swaging: Swaging is a process of cold-forming metal or plastic by applying pressure to create a secure joint. If your tubes have some flexibility, you might be able to swage the Teflon tube to fit inside the silicone tube. This process may require specialized tools and expertise, so it's recommended to consult a professional or explore this option if you have experience in swaging.

Remember to test the chosen method thoroughly to ensure it provides the desired sealing properties and meets your requirements.
