Precision-machined transition fitting for hybrid pneumatic systems requiring metric-to-BSPP thread conversion. Features 6mm wrench flats for tool engagement and chamfered ports to prevent tube abrasion. The cold-forged brass construction ensures 250% higher fatigue strength compared to standard fittings.
- Interconnecting ISO 15407 and JIS B8381 components
- Retrofitting European machinery in Asian manufacturing lines
- Vacuum system instrumentation connections
- Medical gas panel distribution blocks
- Robotic end-effector tool changers
Installation protocol:
Apply 2-3 wraps of PTFE tape on male threads starting from second groove.
Use backup wrench on hex body during assembly to prevent torsion damage.
Pressure test at 1.1× system pressure for 10 minutes post-installation.
