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?
