PB Pneumatic Fittings are bulkhead-type push-in connectors used to connect pneumatic tubes through a panel or machine wall.
Unlike standard PC straight fittings, PB fittings include a fixing structure that allows the connector to be securely mounted on equipment panels.
They are commonly used when:
- Air tubes need to pass through machine plates
- Pneumatic lines require fixed positioning
- Equipment requires clean and organized piping layouts
