ABS plumbing fitting at blank tank

[s-m-h]

Gents,

I am reinstalling my bathroom and getting to work on the plumbing; waste part first. At the junction where the 2" male piece fits into the actual
black tank fitting(2" female) through the floor, there is a fair amount of slop. I felt inside the female fitting and it feels as though there is
groove for an o-ring. I suspect you aren't meant to glue this piece so it can be removed later if necessary so it makes sense an o-ring would be
utilized. I noticed when I pulled it out the PO just had it smothered in silicone.

My question is; assuming I just need an o-ring, is it some sort of specialty o-ring or any department store jobber will do? Or am i simply wrong about
how these fittings go together?

Thanks.

OK Shawn,

There is not reason to believe that this is anything like OE. I can assure you that the RTV was not OE.

The OE tanks had female pipe flange fittings spun welded into them. an adapter was threaded into the flange and there was supposed to be an O-ring so
the drop pipe could go in there and seal. That way the movement of the pipes didn't break anything. This is actually all in the parts book. There
may be a part number for the O-ring there too.

Thanks Matt! Good to know I wasn't too far off track. I'll have a gander at the parts book.

You are correct that GM used a slip fitting. Bad idea!
Even if you get it back to factory install condition it will still leak in the future.
Here is how I solved the problem years back.

On the other side of the holding tank is the kitchen drain fitting. It also needed revising.

Here is how I did it:

Thanks Emory,

I really wish I would have read this post before I put the tank back in and put new flooring down. Would be tough treading to attempt this now...
