Hose Questions
What does the number (Aqua One Hose 25/32 mm) represents?

25 represents minor diameter and 32 represents major diameter?

I know that 25/32 mm hose will fit 3/4" BSP ...

and to fit newly bought hose, I need to use hot water then attach?

I have no heat gun.

Hi, 25mm is your internal dia. So you would need a 25mm barb which has a 20mm (3/4) BSP male thread. No hot water needed just throw a zip tie around it after. Or slip it over 20mm pressure pipe which is actually 25mm outside diameter, but safer to use barb when pressurised.
