I've used the silicone grease on the small O-rings in Clippard quick connectors. Makes it a lot easier to thread the female fitting on the male fitting. Can get a tube of either material for under $10 that should last a long time. As usual, once you start with a material...you find other uses for it as well. Carl B.
I have found using a cup of water to dip the ends into will make then slick enough to connect but drys up so it does not collect dust and grim quickly.
I use the same Clippard quick connects on the other end of the tube with the glad hands, just remove to seal off the train pipe.
If you're concerned about grease collecting contaminants, give some thought to using a spray can of silicone. Some are formulated to end up perfectly dry, so they don't attract anything, but result in a surface that won't stick. Mold release is just such a formulation.
