PD All-Brass Male Run Tee Push-In Fitting
The PD Series is an all-brass male run tee push-in fitting designed to connect two equal-size pneumatic tubes to one female threaded equipment port.
The fitting can be installed directly into a solenoid valve, pneumatic cylinder, air manifold, FRL unit, regulator, or machine-mounted air block. Its push-to-connect mechanism enables fast tube installation without compression nuts or tube-flaring tools.
The PD Series supports metric tube outside diameters from 4 mm to 12 mm and male R threads from R1/8 to R1/2. Its all-brass construction offers greater body strength than a standard plastic-bodied run tee, making it suitable for industrial machinery, automation systems, maintenance work, and demanding pneumatic installations.
