Intake boot oring lube?

[Lucky13xx]

I'm in the process of changing my intake boots and orings. I'm using suzuki oem replacement parts. Should I use anything to lube the orings? If so what?

Thanks

I have used everything from saliva to grease, to silicone spray to WD-Douche to nothing at all.

It all works. Probably the silicone spray lube.

thin smear of silicone grease works best for me. i use it on all my O rings. (except for brake parts)

People will say to always lube o-rings before installation, but that's really only to protect them during installation. In this case, you're just pressing the rings lightly into a groove with your fingers and then bolting the works onto the engine. There's nothing to slip, slide, or pinch if you're doing it right. I don't think lube is necessary here.

it helps them to seal, helps them stop drying out and therefore aids in removal from certain applications

Although lubrication is not all that necessary, a few small dabs of grease will hold the o-ring in place while you put the boot into place.

This was my take on it. I just didn't want to put a lube on it that would accelerate the rubber breakdown

Don't use regular grease, as petroleum products will cause the orings to swell/expand. It's best to use silicone lube.

Viton O rings are pretty much impervious to anything. The old school junk Suzuki uses, who knows?

What about white lithium grease? afaik, it's not petroleum based.

grease idea

I was at the Sukuki dealer so I already bought that spray white chain grease that is "o ring" safe so that's what I used.

Silicone grease worked for me. Its battle no matter what you use or do

I use Permatex Graphite in oil High Temp thread lubricant, or the copper one. The graphite one matches the color of the castings better. I use it on gaskets too. I do not like scraping gaskets.

Isn't gasoline a petroleum product

Go to Lowes and get a small jar of Plumber's Silicone Grease by Gunk, part number GR2V.
Only a couple of bucks and will last forever.
