Comparison between Mini and Standard
Easy attachment and detachment of tubes despite ultra-compact size. The release ring features an oval shape.

Since its initial launch, the Mini has featured an easy-to-use oval-shaped release ring.
The Standard features a circular release ring, while the Mini's is oval-shaped. This feature is intended to improve ease-of-use.

We offer one-touch fittings for ultra-thin tube piping.
The ø1.8 (diameter 1.8 mm) and ø2 (diameter 2 mm) sizes are suitable for piping to small actuators, etc.
