Thanks, the coils are 1" BSP & I got the adapter fittings for these. The feed & outlet are smaller so I foolishly assumed they were 3/4"BSP so have 2 fittings to take back...Looking at it , you just want 2 nuts and 2 olives from a 22mm compression fitting . Most new cylinders come with them , so you can just pipe up and go ….
As others say they won’t be BSP , but you shouldn’t need any special fittings to make it work . Just the nut and olives .. as most domestic pipe work will be 22mm pipe work unless specified differently .
On the heating coils you should just need some 22mm compression to 3/4 female irons . PTFE up the threads on the cylinder and fit .
Thanks, I was too focused on the threaded straight adaptor type & didn't clock the olive bevel on the fitting... This cylinder isn't ancient although it has sat around for maybe three years. Mine isn't Gledhill but they state "Standard 1 inch male & female tappings with optional compression fittings available " - so not included on all cylinders and not on this oneCompression fittings often have their own threads for joining the 2 parts of the fitting together, Obviously the end thread for connecting to the plumbing is 1/2", 3/4" 1" BSP etc. It was annoying changing a 3 port valve in a cupboard with water dripping out and finding the threads were often finer than the valve you were replacing requiring replacing the old nuts and olives while trying to catch the water. More often than not 1/2" comp fittings also had a 1/2" BSP thread but I have never seen that on any larger fittings.
Most cylinders now come with the compression fittings moulded into the cylinder.
