A Metal PU Fitting T-Joint 4mm is a pneumatic connector designed to split a single 4mm tube into two separate lines, forming a T-shaped connection. Made from durable metal, this fitting ensures secure and leak-free connections for pneumatic systems. The T-joint allows for easy branching of airflow or fluid lines in systems where multiple directions are needed, typically used in industrial automation, air compressors, or robotics. The push-to-connect design provides quick and convenient installation.
