Plain air/steam inlet tube for use with size 13 screwcap adapter. Because the adapter allows variation in depth of immersion, the tube can be used with flasks of various capacities.
This item has a jet drawn on one end and is included in the range for the benefit of customers who do not have the correct size of tubing available. The screwhead adaptor QST 53/13 is not supplied and should be ordered separately.
