Have you guys used temporary rubber assembly lubricant, while working on cars, trucks, or machinery ? Is it the same or different forumulation as tire mounting lubricant ? I already have the latter, but it didn't make the cut on a recent rubber hose connection that was extremely dificult to connect while I was working on the engine of an old truck.

I use dielectric grease. It's almost too slick though. You can also try Red Rubber Grease which is used for rebuilding motorcycle brake calipers.

For my purpose here I could not have used silicone grease, as the SAE hose in question was for carrying glycol based engine coolant under pressure onto a very small connection on a preheater circuit.

I have a lot of silicon lube but for coolant hoses and o-rings I just use dish soap.
Same for windshield's and such.

water plus a drop of dish soap

Work on everything from small single cylinder to 95L Cummins diesel and we use a light wipe of plane old white lubriplate no 105 assembly grease on all coolant hoses. Rubber, stick and silicone hoses they all get a light wipe mostly on the fitting so the hose pushes any excess grease out of the cooling system

Yeah. It’s a commercial formula that is all initials (P80 emulsion temporary lubricant … )and smells like rotten fish and is white. Soapy water is a fair alternative.

It’s used in Brake and fuel line production.

I replaced the rubber base of my van antenna as it broke away. A friend suggested Vaseline and it worked. I still did not get it seated all the way in its retainer groove because I don't have the hand strength.

SilGlyde is my go to rubber lube, safe for o rings, brake calipers and much more, one tube lasts a long time. Highly recommend a tube every garage or tool box.

Dish Soap, a little dab'l do ya....

Silicone spray works for me.

Cheap dish soap was used during original assembly, I'd bet.

Using petroleum based lubes on rubber that's not meant for it is a good way to get to do the job again.
A lot of rubber doesn't react well with petroleum.

Spit.
Works well on rubber hoses, seriously...

Dish soap if I run out of spit

The worst item I have ever assembled were the carburetor inlet tubes on a Honda 750cc V-4. Yes the same as my username. Two side draft and two downdraft carbs. It is a 90 degree V engine and they can be a bit of a cast iron bitch to get back into position. The original advice was to use Armor All as the lube. I hate that stuff so I use Dawn soap/water now

People who mount motorbike tires recommend Windex. I'm guessing because it works, and also that it evaporates quickly without residue.

Yes, but what kind of dish soap works the best? And the water, tap, distilled, deionized, pH balanced, etc.?

Dawn dish soap for all things dish soap related.
