PB All-Brass Male Branch Tee Push-In Fitting
The PB Series is an all-brass male branch tee push-in fitting designed to connect two pneumatic tubes to one female threaded port. Its T-shaped configuration divides one compressed-air connection into two tube branches while keeping the installation compact and organized.
The fitting uses a push-to-connect mechanism, allowing pneumatic tubing to be installed without additional tools. The male threaded connection can be mounted directly into a solenoid valve, pneumatic cylinder, air manifold, FRL unit, air tool, or other pneumatic equipment.
With tube sizes from 4 mm to 16 mm and R threads from R1/8 to R1/2, the PB Series covers both compact pneumatic devices and higher-flow industrial air circuits.
The all-brass construction provides greater mechanical strength than standard plastic-bodied push-in fittings, making this series suitable for industrial equipment requiring a robust, heat-resistant, and durable pneumatic connection.

Product Structure
The PB fitting has three connection points:
- Two horizontal push-in ports for pneumatic tubing
- One vertical male threaded port for connecting to pneumatic equipment
The internal push-in mechanism holds the tube after insertion and provides a sealed pneumatic connection. The two horizontal ports use the same tube outside diameter.
The male thread is positioned at the center of the fitting, creating a compact and balanced T-shaped air distribution point.
