How to Put a Wire in a Tube
 

It doesn't take long to figure out that we run all of our wires through clear PVC tubing.  We do this for a few reasons:

  • Tubing protects the cable inside from abrasion damage
  • Forms a waterproof junction when used in combination with a barbed fitting
  • Acts as a strain relief

But the biggest question is how do we get it in there?

 
Start with a string that's a couple of feet longer than the tube.

We use a nylon string and "fuzz up" the end a little.
 
Stuff the "fuzzed" end into the tube.
 
Use an air gun to blow the string through the tube.

It goes really fast so you might want to hold onto the other end.

Put a loop on one end of the string, and loop it over the end of the wire.

Un-jacketing the end of the cable helps.
 
Fold the exposed wires back onto the cable to secure the loop in the string.
 
Pull the cable through the tube.

It helps if someone else holds the other end of the tube and pulls it straight.  But it is possible to do alone, just tie the loose end of the string to something and "walk" backwards with the tube in tow.
