Industrial Applications

1. Compact Pneumatic Valve Manifolds

Routing small-diameter control air (4 mm tubing) from highly packed miniature valve manifolds in restricted automation enclosures.

Problem Solved

Standard straight fittings require too much vertical clearance, causing tubing bend radius violations and potential kinking. The compact L-shape, 8 mm AF hex, and M5 thread of this mini fitting allow for high-density side-porting without flow restriction.

2. Cleanroom Pharmaceutical Packaging Assembly

Providing reliable pneumatic routing on small sorting and pick-and-place actuators in ISO Class 4 pharmaceutical or medical device packaging lines.

Problem Solved

Standard fittings can shed particulates or outgas paint-wetting impairment substances. This fitting's certified ISO 14644-1 Class 4 cleanroom suitability and VDMA24364 Zone III (LABS/PWIS) compliance ensure it won't contaminate sensitive pharmaceutical products or cleanroom environments.

3. End-Of-Arm Tooling (EOAT) for Light Pick-and-Place Robot Grippers

Supplying compressed air or low vacuum (-0.95 bar) to mini suction cups and pneumatic micro-grippers mounted on high-speed robotic arms.

Problem Solved

High-speed robotic motion demands extremely low payload weight and secure tubing retention. Weighing only 3.55g, this fitting minimizes EOAT inertia while its stainless-steel clamp and POM release ring prevent accidental tubing release under high dynamic G-forces during rapid cycle times.
