Grandesys adapter piece 1/2 to 3/8 inch

The adapter piece is only functional for customers with a 3/8 inch water connection and in some cases saves the purchase of a new water supply hose if the water supply hose is the right length.

The adapter piece 1/2 to 3/8 inch is screwed onto the thread of the cistern with the corresponding rubber seal. The water supply line is then screwed on and tightened on this adapter piece.
