Or run a generous bead of cheap bathroom silicone around a 6mm rod and let it set........

.

Honest question, Benjamin [because I've never tried what you suggest] : How likely is that to stretch to clear Ian's 15mm connector ?

I would say quite likely to be honest. And it only costs ?1 from ?land so worth a try. Its Cheaper than E6000 elastic glue and available everywhere.

I required a similar solution to seal the tether command cable for a small underwater UAV - I found two options - SKIFFY, a company that supplies plastic and rubber fittings, screws, grommets, etc. They had a pale white grommet that was very soft - It was not a doughnut, but a panel grommet, ie, with a slit on the outer periphery to fit the sheet metal panel. The one I used was 8mm ID and 16mm OD and stretched over a 24mm plug with some lubricant applied. Some did snap in the process.

The second, and finally better option, was Silicon tubing from the local hospital - used in the peristaltic pumps, OD of 14mm, ID of around 6.5. I fed the tube into a metal tube of snug length, let an 8mm section protrude and cut it of with a Stanley type knife blade. That little ring stretched over 28mm internal without snapping. Make sure to get the silicon stuff - they also have what looked and felt like polyethylene which is unsuitable.

Siligum is another option. Two-part silicone that sets in minutes and very stretchy (used for moulds available in Hobbycraft)

Forgot about that stuff Neil, if i remember it can go pretty hard after a while... for any small low repeat/single use molds I need I use a mix of the aforementioned el cheap-o silicone sealant and Corn flour!....it doesn't set that fast though. Flexible but not all that stretchy.

Another vote for Sugru from me. Very useful stuff.
