2 - 1/2" pipe connections

[Tuttles Revenge]

So this hasn't come up for me in several years.. 15 or so.. But in a current project we cut and need to connect to a 2.5" galvanized steel vent that goes up into the finished floor above. Does anyone know of a legal UPC approved method for making this connection? Last time I did it I used the "ask forgiveness" technique of my inspector as I showed him the Victaulic tee and Roust-A-Bout clamping fittings used.. I got a properly sloped tee and in 2.5"... But still no UPC stamp. Fortunately my inspector chose to "not see" the connection and its good and buried. But I've got to pass it off again and would rather have a fitting that I don't have to worry about. Currently we have a Fernco unshielded sewer coupling... but as many times as we see them and they do the job... they don't have that approval..

anyone got the answer?

I don't know where you ever found a "properly sloped tee" AND a Fernco unshielded coupling in 2 1/2" size, in the first place.

2.5" OD pipe? That would be a standard metal wrapped Mission or Fernco for that.

I don't know how available it is. "Call for pricing".

I think I found another solution since the Mission style band is a factory order. Dresser couplings or Compression couplings are readily available in 2.5" (Seattle at least) and I can get PVC in pressure pipe to make a transition to 2" or 3" depending. Going to the site to see what the next step if any will be.

Mission couplings are standard fare in Seattle. If you have galvanized pipe in either a 1.5" or 2" size, you can find the correct couplings at any hardware store.
OD on 2" galvanized is about 2.5"
There are several brands of fittings that are similar in function for that.
