Rocket O-Ring Steam/Water Wand 6x1.2mm – Genuine Spare Part
A quiet hiss, a warm burst of steam – and the milk begins to spin into fine swirls. What makes this moment reliable usually sits out of sight: a small sealing ring on the steam and water wand, keeping pressure and heat exactly where they belong.
Rubber and silicone seals change over time – every heating and cooling cycle takes a toll on the material until it loses tension and no longer seals completely. A fine drip at the wand or a slight hiss alongside the actual steam blast is usually the first sign. The replacement is straightforward and, for us, belongs to the normal care of an espresso machine – no major intervention, just a small gesture that makes your next cappuccino as silky as it was on day one. Good maintenance is, to us, part of the enjoyment, not a detour from it – though that too is just our opinion, one of many.

Roastery Tip
From the roastery: for most of us, Cozy Chocolate and Nutty Delight are the starting point – full-bodied, aromatic, dense. Anyone looking for maximum body with no acidity at all finds in Very Nutty their favourite. And for anyone curious about a fruity experience: Wild Peach is our discovery for the moment after. Our recommendation – one of many, every bean finds its people.
