I'm having a stupid moment. I need 1" female to 22mm male adaptor to fit a Rayburn boiler but online I cannot tell which 'end' is which http://www.screwfix.com/p/female-coupler-22mm-x-1/50777 for example.
Please someone point me in the right direction as I cannot get to the plumbers merchant and want to pressure test the boiler.
Thanks
