Aquaflow 110mm Soil 92.5 Degree 2 Boss & Cast Iron Pipe

[Possom]

Would a 4 inch diameter cast iron pipe fit into the top of this and also the bottom of the Aquaflow 110mm product, or would any additional adaptors be required?

The horizontal would be attached to a 110 mm plastic soil pipe.

Thanks.

Cast iron and plastic soil is not compatible adaptors required,
Unless it's very awkward why not change the lot?

Thanks. Yes it is awkward as a section of the iron pipe goes immediately a heat outlet from an oil boiler so this part has to remain cast iron.

I'm wondering if I'd require the first product above which has a socket end on top/bottom, whereas the second product only has a socket end on the upper end.

Whichever fits best if you can get the second one to work cuts a joint out.
