Joining Imperial Copper Piping to Metric

[bluefunnelline]

Good Morning

My house is fitted with imperial measurement piping. Only metric is now available

My Question
========

Can I use a 10mm straight through connector to connect 3/8 inch pipe to 10mm
Can I use a 10mm straight through solder connector to solder a 3/8 inch pipe to a 10mm

Can I use a 15mm straight through connector to connect 1/2 inch pipe to 15mm
Can I use a 10mm straight through solder connector to solder a 1/2 inch pipe to a 10mm

Can I use a 20mm straight through connector to connect 3/4 inch pipe to 20mm
Can I use a 20mm straight through solder connector to solder a 3/4 inch pipe to a 20mm

Many thanks

Jimmy

Don’t you have to use a 15mm straight compression connector with a 1/2” olive on one side and the same with a 22mm connector using a 3/4” olive?

You can get solder connectors too.
