Description says ABS cement. I know there's one available now that'll do both.
Beat me to it. Was going to post but had to go out this evening. Yes, get a Valterra T1029-2 and first slide it up to the pins. If it fits without a lot of slop, carefully cut away the pins, file them smooth, use some alcohol and scotchbrite to throughly clean the outside of the stub and also scotch brite the inside where it will be glued. Clean is the word here. Then using a liberal slathering of cement designed for ABS on both the stub and the inside of the termination, shove it on and HOLD IT in place till it sets so it won't slide half way off. I have one of these I bought to build an extension for my trailer, I ended up with a clear 6 inch extension that did the trick. (bad Bigfoot design again, put the sewer cap more than 12 inches under the trailer where you had to put down a trash bag or similar and LAY DOWN to reach it.)
