I will check tomorrow at the local Aubachon but after looking at the Heycoa link I did some further research because I could not figure out how to order them off of that website and found this site:
ElecDirect Cord Grips - Cord Grip Connectors, Cable Glands, Strain Relief Connectors
Yes I want to use these both for electrical and tubing like the below photo:
Just I'm planning on doing mine on a 5 gallon bucket and am going to try and rig it so the heater and Co2
reactor also fit inside it.
Not sure if I'm going to use that lid I ordered a gamma seal lid so it can screw off but that may be a problem if I have the reactor hanging from the lid like the below photo shows:
But who knows its a work in progress and I'll see how it comes about when the rest of the parts arrive.
