The 2 primary reasons we recommend lubricating a tube are:
- for flowcaps - If you notice your caps are tight or sticking to the outside of the tube you can apply a thin layer on the outside of the tube where the flowcap sits. This will make it easier to install / remove the flowcaps.
- for staff connectors - If you notice that your staff connectors are not twisting smoothly, you can apply a thin layer of lube to the inside of the tube where the staff connector fits. This should make it easier to install / detach the staff connectors.
Please note, oils or lubricants containing esters or polyglycols, common in motor and gear oils, can break down polycarbonate and should not be used to lubricate your tubes. WD-40 and any mineral spirits are also NOT good for polycarbonate. If you would like to geek out more on chemical resistance of polycarbonate, click here!
