OEM product. Fits Rancilio models that have a wand with a 10 mm outside diameter, and each thread is 1 mm apart from peak to peak; 1.0 thread pitch. 1.5mm holes, 25 mm length. Part #25111006 replaced old part #23212033 - 02/2022.
Sorry, this does not fit the version 1 or 2 Silvia models. It will fit the version 3 model, but with four holes the steam would exhaust so fast, it probably isn't an applicable part.
