Hi @RoryV - [Something like this has](https://discuss.bluerobotics.com/t/trying-to-pass-oil-through-bluerobotics-bulkhead/14695/6) been done before! The main question is - how deep does the enclosure need to be (what is the external pressure?) If you’re not going too deep, you can drill out the appropriately sized Penetrator Bolt to eliminate the cable step, and run your tubing through it. The more rigid the tubing is, the better the WetLink Penetrator seal can compress against it. The better the compression, the higher the pressure in the sealing material, which drives the depth at which external pressure overcomes it and a leak occurs. Too squishy a tube and you won’t be able to submerge to very deep without a leak occuring, and generally extreme depths (\>60-100m)) may have issues with the tubing “extruding” as there is no “step” in the tubing to prevent this motion like the jacked of a cable creates. --- _[View the full topic](https://discuss.bluerobotics.com/t/submersible-sampler/21661)._
