Ascaso Steel Uno Complete Steam Valve Assembly (Post-2019) Complete steam valve assembly for Steel Uno models made after 2019, featuring a rear-facing 1/8" 90° steam supply fitting and a 3/8" zinc fitting for the steam wand. Discontinued, limited stock available. SPECIFICATIONS Rear-facing 1/8" 90° steam supply fitting 3/8" zinc steam wand fitting 5mm D-shaped knob pin COMPATIBILITY Fits: Ascaso Steel Uno, manufactured after 2019 only INSTALLATION Moderate plumbing job, isolate steam pressure and drain the boiler before removing the old assembly. For pre-2019 models, call 1-800-459-5594 or email info@espressoparts.com to confirm the correct part. PRO TIPS Don't assume "Steel Uno" alone is enough to confirm fitment, Ascaso changed the steam fitting orientation and knob pin shape at the 2019 revision, so a pre-2019 machine needs the older assembly, not this one.
