A precision-machined pneumatic connector featuring dual counter-rotational wrench flats for secure installation. The electroless nickel plating provides corrosion resistance in humid environments while maintaining smooth surface finish (Ra≤1.6μm) for optimal sealing. Designed for compact pneumatic circuits requiring right-angle-free connections.
- Modular pneumatic manifolds in robotics
- Sensor air supply line connections
- Medical device pneumatic assemblies
- Precision pneumatic tooling interfaces
- Laboratory equipment gas distribution
Installation protocol:
Apply 1.5-2 wraps of PTFE tape on male threads using clockwise winding.
Tighten with 6mm hex wrench at 1.2-1.5N·m torque. Avoid overtightening
which may deform NBR seals beyond 0.3mm compression limit.
