High-precision metric-to-BSPP thread adapter with concentric sealing design, featuring anti-vibration grooves and double O-ring structure for leak-free connections. The stepped reduction design (PG8 to G1/4) enables smooth flow transition while maintaining compact dimensions. Compatible with pneumatic tubing OD 12mm at PG8 side and 8mm at G1/4 side.
- Industrial robot pneumatic gripper interfaces
- CNC machine tool sensor air line conversions
- European machinery retrofitting (metric to BSPP adaptation)
- Compressed air distribution in tight cabinet spaces
- Vacuum system component interconnections
Installation protocol:
Apply thread sealant only on male threads (PTFE tape or liquid sealant).
Avoid overtightening - use torque wrench for critical applications.
For vacuum systems, install with O-rings facing pressure source.
