Bought from importer never used. Comes with adaptor pipe and rubber seals.
These cost like twice what I have advertised it for new. it's cheap ok
The pipe sizes are 55mm on one end and about 63mm on the other. (internal diameter) NOTE the rubber orange seals can accomodate for a significant difference as they fit over the piping and are 65mm diameter and 70mm (inner diameter)
Only reason it is not being used is the supra really needs a plumback system and I am going to have to buy a different product.
so if you know anyone who wants one or you want one..
