A precision transition fitting engineered for hybrid pneumatic systems requiring metric-to-PG thread conversion. Features dual-thread anti-loosening design with 360° rotatable collar for tool-free adjustment. The chrome-free surface treatment meets RoHS 3 compliance, making it suitable for cleanroom environments.
- Interfacing European equipment (PG) with Asian pneumatic components (Metric)
- Vacuum system instrumentation connections
- Coolant line adapters in CNC machinery
- Sensor mounting brackets in semiconductor fab systems
- Retrofitting legacy pneumatic circuits
Installation protocol:
Apply Loctite 577 thread sealant (non-hardening type) on male threads.
Use opposing wrenches during tightening - 13mm open-end wrench on PG8 hex
and 8mm flare nut wrench on M5 side. Perform pressure test at 1.5×
working pressure after installation.
