Small T-shaped connectors to easily add an oiling tube to a 2mm stern tube that runs a small (e.g. 1mm diameter) prop shaft in an RC model. Lightweight design, no welding needed, just glue two 2mm tubes together and drill a hole to add some drops of oil to ensure your prop shaft is well sealed against water coming in throught the gap between the stern tube ("Stevenrohr") and the prop shaft ("Welle"). Contains 4 pieces on a sprue.
