Cast Iron XH vs NH sizing / Charlotte / NewAge Casting

[djfremen]

Hey Gang,

I'm scratching my head with old school XH. I have a 4" XH pipe around 90 years old. I want to cut in and fernco a No-Hub Wye to ABS.

On the buying website it doesn't say XH but instead

Charlotte NH 00020 1800 Pipe 45 deg Wye-Branch, 4x4x3 in, Spigot, Cast Iron, Black, Domestic
Item #: NHYPPM Brand: Charlotte UPC: 611942002184


So, I then checked out Charlottes
Catalog and only see XH with hubs.

4 x 4 x 3 in. Spigot x Hub Extra Heavy Cast Iron Wye
Part #XHYPPM | Manufacturer Part #XH 00044 1400

It looks like ID is smaller on the nohub.

They don't make XH version just NH... Thoughts?

The i.d. measurements are the same, it is the o,d, the varies.

Rather then using a Fernco I would strongly suggest a mission coupling

Ah! That makes sense now. Thanks much.

Yep. Stainless steel mission all the way.

Well, not thrilled with the mission clamp or the standard Fernco

There's a mismatch with ID.

Be rid of the P1066-44 P1056-44 and replace that with a banded coupling. I suggest you measure the pipe ODs with your long-reach digital caliper. There are a lot of sizes offered.

Do warm up to the one with the purple label if it fits.

You have to use an XH x SV/No-hub mission coupling. Then you will not get the distortion.

I just don't understand. Fernco's P3000-44 is exactly the spec I need. Mission doesn't mention XH

I need 4" CI to 4" CI XH

Fernco Proflex 4 in. x 4 in. Neoprene Shielded Coupling

I'm throwing in the towel and just replace the XH run. It's worn anyhow.

A Fernco shield coupling can be used as can the mission couplings.

Your old cast iron pipe had no defined outside dimension when it was manufactured. Outside dimensions were not necessary because each fitting was made from inserting a roughly the same outside dimension pipe into a roughly dimension fitting hub and the void filled with lead. Sometimes you will have to use a banded coupling that is specified for a different diameter makeup than what you think you're using it for. Only new pipe has standardized outside dimensions.
