I have a tight spot in the attic crawl where a new waste vent for a new sink will go. It would be easier to use 2 neoprene transition couplings for 1-1/2 inch ABS to 1-1/2 inch ABS, if there is such a thing, instead of using ABS adhesive in this position. Is there a Proflex/Fernco/PlumbQuick or Mission part that will do it? This is the type of coupling I am talking about but I can't understand Fernco's or Mission's descriptions. The letters ABS do not appear in these descriptions. https://www.fernco.com/plumbing/shielded-couplings/proflex-couplings https://missionrubber.com/products/band-seal-specialty-couplings/ Why I'm doing it: I might need to undo it a few times (less than 3-4 times) over the next few years in order to get access to a corner of the house that will be blocked by the new vent pipe. If you tell me I will need to replace the couplers every time they're disturbed, fine. It's true I could try to route it around the access route and use ABS adhesive instead, but there are safety risks in the alternate route. The alternate area is even tighter and there is knob and tube wiring there. I believe it is not practical to rewire.
