Sourcing Evaluation Checklist
Three essential checks to evaluate accessory compatibility and listing descriptions.
01
Ear Cam Profile & Thickness
Cross-reference grouphead collar depth and wing orientation against listing schematics to ensure a secure lock-in fit.
02
Puck Screen Clearance
Check if your group shower screen screw protrudes into the basket headspace, which can contact puck screens during extraction.
03
Base Piston Sizing
Review basket inner diameter listings carefully, as standard tampers may leave uncompressed coffee around the basket perimeter.
