MAMOD KIT BOILER KNURLED UNION NUT - PIPE TO BOILER JOIN

 UNION BRASS NUT & 0 RING

You will need this joining-knurled-nut that secures the steam pipe to the boiler 
if you have a KIT TYPE boiler that requires no soldering. 

 Cannot be used with a standard soldering type boiler.

• On the Mamod kits the steam pipe is not soldered into the boiler but uses a compression fitting like this. Fit the steam pipe through the brass nut and the O ring over the copper pipe and screw the nut into the boiler
• This will compress the O ring and form a steam tight seal
• Not suitable for non kit models
