Ascaso Steel Duo One Hole Steam Tip — 1mm Single-Hole No-Burn Replacement

This Ascaso Steel Duo one hole steam tip is a premium 1 mm aperture replacement built for the 8.50 mm male-thread no-burn steam wand fitted to the Ascaso Steel Duo and Steel Duo Plus. Threading this Ascaso Steel Duo one hole steam tip onto your factory wand delivers a tighter, slower steam jet and the dense, glassy microfoam home baristas chase for café-grade flat whites, cortados and latte art.

The Ascaso Steel Duo is one of Spain's most refined home espresso machines — dual boiler, PID, and a precision-engineered no-burn steam wand built to the 8.50 mm male-thread standard widely used in the higher-end home espresso machine category. That gives Steel Duo owners access to a specialist class of replacement steam tips, and a 1 mm single-hole aperture is the sweetest spot for home pour-art.

Steel Duo's steam pressure pairs beautifully with a one-hole tip: the boiler's energy delivery slows just enough through a 1 mm aperture to give you a longer, more controllable stretch and a microfoam that pours like wet paint.

The Ascaso Steel Duo is Spain's flagship home espresso machine — a dual-boiler design with PID temperature control on both the brew and steam circuits, hand-finished aluminium body panels, and a precision-engineered no-burn steam wand built to the 8.50 mm male-thread standard. Ascaso's engineering choices give Steel Duo owners access to specialist replacement tips that elevate steam-side performance well beyond what stock components offer.

Because the Steel Duo's steam PID holds pressure tighter than most home machines in its class, you get unusually consistent flow through the steam wand — and that pairs especially well with a single-hole tip. The combination of stable pressure plus 1 mm aperture produces a long, predictable stretch window that is hard to mess up, even on small 5 oz pitchers for cortados.
