A PB fitting joins a threaded air port to a straight run of pneumatic tubing. Two tubes enter from opposite sides, while the brass male thread points down from the centre branch. This layout is useful when the tube needs to continue past a valve, cylinder or manifold connection. The pictured fitting is a simple connector; it does not regulate airflow.
Use this style of tee where an air line runs across a machine and also needs to connect to a threaded component below it. Common locations include cylinder ports, valve manifolds, assembly fixtures, packaging machinery and compact control panels. It can also provide a neat branch point when two tube directions must share one threaded air port.
Order the fitting by tube outside diameter and male thread size. A typical code is written as PB06-02, where 06 refers to 6 mm tube and 02 commonly identifies a 1/4-inch thread. Coding varies between manufacturers, so please state the tube OD, thread standard and thread size with your enquiry. Metric tube choices commonly include 4, 6, 8, 10 and 12 mm. BSPT, BSPP, NPT and metric threads should not be treated as interchangeable.
No. The pictured PB fitting has no adjustment needle or knob. It is used to connect and branch an air line.
The usual PB version has two equal push-in ports. Ask us to confirm if a reducing combination is required.
Shut off and vent the air supply first. Press the blue release ring toward the fitting, then pull the tube out in a straight line.
That depends on the thread version supplied. Some tapered threads have sealant applied at the factory, while parallel threads may use a sealing washer or O-ring. Confirm the thread type before assembly.
