can I use silicon lubricant on PVC Vent adapter?
I see that Z dens makes a polypropylene gasket lubricant. That product says it's guaranteed up to 230 F max flue temp. unfortunately I don't have any of that and I'm having a hard time getting the schedule 40 into the PVC vent adapters. I feel like I would risk tearing the gasket if I were to force it in there. I surely wouldn't be able to get it back out if I wanted or needed to. My question is, can I use a silicon lubricant on the rubber gasket instead of a poly lube? The silicon says it's good for up to 500 F so the temp won't be an issue and silicone seems to be compatible with most material. Any concerns?

You can choose to do what you want, but you cannot choose the consequences.

Isn't most common way to use soapy water? A shot of dish soap like Dawn or Palmolive and some water and you're good to go?

But it won't dry up like the soapy water will, causing the stuff to really lock together. The silicone will continue to act as a lubricant which in my opinion is bad in this application.
I'd wait until you find the correct product.
There were some gasket failures in the western states with those pp venting products, in the cases I'm familiar with, installation error was the fault.
The slope on horizontal runs is critical for flue condense doesn't lie around the bell of the piping the gasket connection, so that gasket detail is certainly under scrutiny, once a failure is documented.
Keep your self, and your customers safe.

I had a Kitec rep tell me one time to use "spit" on thier orings to make them slide right on. I asked him for the official Kitec recommendation to use spit, and asked him what pH it needed to be etc. He was at a loss for words.

Use only genuine Kitec spit©
Using genetic oil in your mower probably isn't life threatening.

Depends on which attorneys the jury choses to believe.
All the tradespeople, fuel suppliers and product manufacturers and their teams of lawyers were pretty clear on the cause.
The HO had blocked off all the combustion and any fresh air into the home, including the duct below the wood stove which was running full till in addition to the boiler. It seems they burned all the O2 out of the home while they slept on a cold December night.
The condition could not be replicated on the discovery day in June, leaving a grey area for the jury to decide fault.
Leave a paper trail, and have everything signed by the HO is one piece of advise.

ChrisJ said "What caused the flue gas to spill into a home?"
Let me count the ways...
Jenn-Aire grill creating negative pressure, causing flue gases to be drawn to point of negative pressure.
Whole house exhaust fans doing the same thing.
Solid fuel appliance creating so much negative pressure in its chimney that it causes back drafting of gas appliances.
Roofers taking a break on the roof decides to sit on the mushroom cap, collapsing it.
Inexperienced workers dry fitting PVC venting system together for modcon boiler.
Boilers sooted up during construction due to inhaling sheetrock dust, blocking flue gas passage ways with carbon and causing major rollout.
Solid fuel converted appliances with no barometric damper to control draft, causing major spillage.
Severe winds causing the "shower curtain" effect, negating negative pressure and causing spillage from the draft hood.
"Carbon monoxide leaks" are a TV phrase which means in most cases they really don't know what caused it, but the blue bodies are a dead give away that it was CO poisoning. In most cases, the conditions that caused the "leak" self corrected before help arrived.
And these are just the ones that I am familiar with. I'm sure Jim and Tim can probably add plenty to the potentials.
It's not something to be taken lightly, and is the most preventable means of death and inadvertent poisoning.

You're saying just in case it does happen, cover your caboose.
I don't trust the "use only our brand of lubricant". I do see @hot rod 's point though when it comes to something going wrong. This is why I asked.
This doesn't mean I don't take CO seriously.
My networked CO detectors are slowly spreading and I have one only a few feet from the water heater and boiler. I also make modifications with great caution when it comes to repairing drafts because I realize I need a lot of air for the boiler and water heater.

Unless manufacturer has specifically tested and lists it as approved for the application, you are out of luck in court when someone has died. Not that I completely agree, but you can certainly see the logic in that model.
