Mechanical movable tube, should not leak liquid

@monicar376

Hello, I’m interested in assisting with your movable tube project. To ensure the correct solution, I would like to clarify a few technical details first: What type of liquid will flow through the tube? Is the tube telescopic, sliding, or rotational? What is the operating pressure range? Required dimensions (length, diameter, movement range)? Do you need a CAD design, prototype concept, or product sourcing? For leak-proof movable systems, common engineering solutions include: O-ring dynamic seals Double-lip seals PTFE sealing rings Telescopic tube designs with internal seal grooves Compression fittings depending on pressure level Once specifications are confirmed, I can: Provide a mechanical design concept (with CAD if required), or Recommend a reliable ready-made solution if this is a sourcing request. I look forward to understanding your exact requirements so I can propose the most practical and cost-effective solution. Best regards,
