Overview

The 12mm to 10mm Stem Reducer is a precision-machined push-fit adapter designed for professional pneumatic systems where tube diameter transitions are required without sacrificing flow efficiency or connection integrity. The nickel-plated brass body resists corrosion in workshop and industrial environments, while the NBR O-ring seal maintains an airtight connection across the full rated pressure range. Push-fit installation requires no tools — insert the 10mm tube and the collet grips instantly, rated to hold under pressure. Ideal for compressor lines, automation circuits, and workshop air distribution networks.
