The same siphon as the 2.5in scale steam siphon offered, but smaller! This model is sized with 1/4in diameter steam inlet and the suction and discharge connections are sized to fit a piece of 1/8in NPT pipe. The pipe can be soldered in using regular plumbing solder. Threading the siphon is not reccommended due to the hardness of the material and the thinness of the walls.
The brass and bronze models do not come ready to use due to the limitations of plaster casting. The nozzle will need to be drilled out to 1/16in clear through. A dimple is provided to help center the drill bit in the nozzle.
