Lubricate rubber jacket of wire to go through a cable gland

[JJJJ]

So this will not be a formal wire pull per say. Trying to fit a piece of wire with a rubber coating via a cable gland. It will be a snug fit and I only need to feed about 12 inches so I can do some wiring in a box.

Most lubricants say not to use on a rubber jacket. Looking for a suggestion. Thank you in advance.

You can get the proper lube from your local electric supply store.

Use a non petroleum lube like Silicone grease or dielectric grease. I've seen small packets at the auto parts store for light bulbs so the contacts don't corrode. I use this:

Amazon.com

OR
Mercedes Benz sunroof lube its made to be safe for plastic, rubber and composites.

This actually worked out nicely once I reversed the direction of the gland with the dialectric grease. It is still water tight but may still put a coat of RTV on the seam as a precaution.

On a related note, Had a project that used 1/2 inch Liquid Tite. Found out that 1/2 creates a perfect tight bond when positioned inside of 3/4 Liquid Tite.
