Mini Bulkhead Tube Coupling Fitting
4mm I/D × 6mm O/D — Precision Brass Construction
Panel-mount push-fit connector engineered for compressed air systems demanding zero-leak reliability at up to 35 bar. Compact form factor. Industrial-grade performance.
When a pneumatic system demands a clean, permanent panel penetration without compromise, the mini bulkhead tube coupling is the professional's choice. Machined from solid brass for corrosion resistance and long service life, this fitting locks 4mm I/D × 6mm O/D tubing securely through any panel, bulkhead, or equipment housing — delivering a leak-free push-fit connection that holds firm under continuous industrial cycling.
Engineering Excellence
Key Features
Solid Brass Body
Precision-machined brass resists corrosion and withstands continuous pressure cycling in demanding workshop environments.
Push-Fit Lock
Tool-free tube insertion with positive collet retention. Releases cleanly with a single collar push — no thread tape required.
Panel-Mount Design
Bulkhead body passes through panels up to standard thickness, secured with the supplied locknut for a flush, professional finish.
High Flow Rate
560 L/min at 6 bar ensures unrestricted airflow — no bottleneck in high-demand pneumatic circuits.
Wide Temp Range
Rated −20°C to +80°C for reliable performance from cold-start workshops to heated industrial enclosures.
Compact Mini Profile
Space-saving mini-series dimensions suit tight panel layouts and compact machinery without sacrificing rated pressure.
