MAMOD KIT BOILER - UNION NUT

 Brass Union Knurled Nut & 0 Ring

• 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
