Product Function
PV fittings are designed to connect two pneumatic tubes of equal size while changing direction by 90°, reducing the need for multiple fittings and simplifying pipeline design.
Simple structure comparison:
- PU = straight union (tube ↔ tube)
- PV = elbow union (tube ↔ tube 90°)
- PC = tube ↔ thread
- PL = elbow with thread
