Full product description
Ascaso Big Dream Group Cap O-ring NBR rubber sealing O-ring used only in the Big Dream group of Ascaso machines, sealing the group cap against the boiler. SPECIFICATIONS Thickness: 2.62 mm Material: NBR rubber COMPATIBILITY Fits: Ascaso Big Dream group only Replaces: Ascaso part #I.4474 INSTALLATION Simple DIY installation with basic hand tools. PRO TIPS NBR O-rings harden and lose their seal after a year or two of daily group-cap cycling. If you're seeing water weeping around the group cap or the cap threading feels stiffer than it used to, this inexpensive o-ring is the most likely fix before suspecting the cap itself.
