Product Function
PM fittings are designed to connect pneumatic tubing through panels while maintaining a straight airflow path.
They are essential for applications where tubing must pass through a panel without changing direction, ensuring clean layout design and efficient system organization.
Compared to elbow bulkhead fittings (PLM), PM provides straight-through connection, making it suitable for linear airflow routing.
