Rated 5 out of 5Â by HEandy Fitting reducers
As one Trade reviewer states, be careful when purchasing these reducers. This particular type is 22 mm diameter (at one end) and are used for applications such as converting 15-22 for insertion into a 22 mm gate Vv (or similar) and then become very useful!
If you only wish to join 15 to 22 mm pipe together then you need the '22-15 reducer,' ie the non-fitting' variety.
Subtle, but they are different parts, enjoy plumbing! :)

Be careful, as I purchased these in order to convert 22mm to 15mm in one go. Unfortunately, these don't fit over 22mm pipe, as they are 22mm in diameter, requiring a coupling
I can't seem to find anything to say what they are, perhaps it was just a mistake on my part.
However, the Hemel branch took them back, and I purchased the correct item.
