Model and connection guide

Tube sizes refer to outside diameter. Mounting threads secure the fitting to a panel; they are different from the female pneumatic port threads. PT is not NPT. Match thread standard, pitch, tube size and installation space before ordering. A blank source specification is shown as Not specified and must not be inferred from another model.

Female-port reference

Source images give approximate identification dimensions of 9.5 mm for PT 1/8, 13.5 mm for PT 1/4, 16.5 mm for PT 3/8 and 20 mm for PT 1/2. These approximate references are not manufacturing tolerances or substitutes for checking the thread standard. M5 female ports are M5 x 0.8.

Installation

Check compatibility and securely mount the fitting before use. Isolate and depressurize the pneumatic system before fitting or removing tubing. Select a model to view its matching English specification image.
