3/4 to 22mm bent cylinder connectors

[gg2000]

I am replacing an old DHW cylinder which has 3/4 female connections whereas the new unit has 3/4 male. I want to connect to 22mm pipe using bent connectors. My question is a 3/4 to 22mm TAP bent connector the correct part to use to connect to the cylinder? I can find listed plenty of 1" to 22mm cylinder connectors by nowhere are 3/4 to 22mm CYLINDER connectiors listed.
Thanks
