Hepworth 22mm to 3/4

[Greenwellies555]

Looking to connect 3/4 copper to 22mm plastic and after rumaging around in my box of Hepworth Fittings I found a pair of what I believe to be just what I need. Problem is one end is white and says 22mm, the other end is grey and says 22mm. The bag they come in says 22mm to 3/4 HD3A/22 GY . The white end has an early style grab ring whilst the grey end a later part green plastic/metal grab ring. I think the white end is the 3/4 but would appreciate confirmation from someone who recognises what I am looking at. Don't want to get it wrong as I think it will fit either way but only correctly one way. Thanks in advance,

Gerry

As a quick reference. 22 should only fit into one end.

Will find a bit of 3/4 and have a look at that in the morning,

Thank you

Ended up phoning Hepworth as Plumbase were unable to confirm one way or the other.
Hepworth Technical said it was a common question and couldn't understand why they had put 22mm on both ends. Despite this the white end is 3/4" so fitted them today and so far so good.
Thanks for replies
