Silicone Hose 4x7mm

Silicone Hose, 4x7mm

This hose is smaller then the intake hose, so it will have a tighter fit on the by-pass valve and Ulka air priming valve (such as the Isomac and VBM mounted one) with the smaller discharge nipple . We recommend switching to this hose if you upgrade from the plastic valve to the brass valve.

Sold by the foot.

This hose is installed from onto the Silvia Pro and Pro X for the air trap. For the Silvia, we recommend two feet (app. length you'll need is 18.25").

NOTE: Most machines/models will require a minimum of two feet. We recommend measuring yours before ordering.
