Shield your counter – and your coffee – from messy expansion-valve discharge with this factory expansion outlet fitting, part A227704363. Machined from low-lead brass then nickel-plated for corrosion resistance, the elbow threads into the E61 expansion valve and routes excess brew water through the drain line instead of onto internal components. A precision-cut taper and burr-free port maintain full flow without adding back-pressure, keeping your pre-infusion and shot timing exactly where you dialled them in.
Key Features & Benefits
Low-lead brass body – food-safe, descaling-resistant and built for years of daily heat cycles
Precision nickel plating – blocks oxidation for drip-free, long-life sealing
Internal full-bore design – preserves expansion-valve flow; no pressure spikes
Standard E61 thread – five-minute DIY installation with a single spanner
Install this genuine Rocket fitting and keep every shot clean, consistent and scale-free.
