Preventing Capillary Action in Hot Chamber Wire Feed-throughs

[likephysics]

I have a strange problem. We test our components in oil in a hot chamber(60-100C). Wires are bought out of the chamber for power supply and data acquisition.
The oil from the chamber leaks on to the wires because of heat and capillary action.
This makes the wires oily and working with oily wire is a time consuming mess. Labels don't stick, they keep slipping etc even with gloves just to mention a few problems.

Capillary action does not bring a liquid to the top of the tube/hole it acts in.
You need a better seal.

The problem with oil on the wires is inside the chamber or outside? If outside, what type of feed-throughs are you using to get through the wall of the chamber?
