About the Airtac PYB Y-Type Threaded Tee Fitting PYB603D
The PYB603D is an AirTAC PYB branch Y, a one-touch fitting that turns a single 3/8in PT port into two Dia 6 mm tube outlets angled away from each other. Push each soft nylon or polyurethane tube into the chuck until it bottoms out and the stainless spring gasket grips it; press the POM release ring to let either leg go again. The threaded stud is brass and arrives with sealant already applied, so it goes straight into a tapped PT port.
This is the resin one-touch spec, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. The D suffix on a PYB changes the whole body to black rather than just the release button, which matters where a dark fitting has to disappear against painted machine frames or cabinet interiors.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac PYB Y-Type Threaded Tee Fitting PYB603D Is Used
Twin mini-gripper pick-and-place head
Feeding two 6 mm lines to a pair of small grippers from one 3/8in valve outlet keeps the end-of-arm plumbing to a single fitting, cutting weight and clutter on a moving robot wrist.
Brewery and bottling actuated valve pairs
Wash stations and fill heads often run paired pneumatically actuated valves off one supply; the Y split takes one 3/8in branch into two Dia 6 actuator lines without a extra tee body.
Woodworking jig clamping banks
Router tables and clamp carts commonly link two 6 mm clamp cylinders to one feed; the angled Y legs route hose cleanly around the jig frame and the black body sits unobtrusively against dark timber and steel.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB603D the Right Part?
Step down to the PYB602 (Dia 6 tube, 1/4in thread) when your valve or manifold port is a 1/4in tapping; step up within this thread to the PYB803 if the legs carry Dia 8 tubing. Note that AirTAC does not list Dia 6 on the PYB 1/2in row, so 3/8in is effectively the largest thread you can pair with this tube size in this series.
Match the thread to the port, not the hose: 3/8in PT with pre-applied sealant suits cast manifold tappings and larger valve bodies. If you need three branches at right angles rather than a Y split, compare the PED male run tee instead. Whichever you pick, the tube OD must match exactly - a Dia 6 fitting will not seal on 1/4in tubing.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
Airtac PYB Y-Type Threaded Tee Fitting PYB603D FAQ
It is an AirTAC PYB one-touch branch Y joining Dia 6 mm tubing to a 3/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum rating -750 mmHg, proof pressure 1.5 MPa, and working temperature -20 to +70 C. It runs on soft nylon or polyurethane tube and ships with sealant on the thread.
A Y angles the two Dia 6 legs away from the port instead of stacking them at 90 degrees, which suits tight machine frames where hose must leave in two directions without sharp bends. Bear in mind that if both legs draw heavily at once, each branch shares the supply from the single 3/8in port, so check the actuator demand rather than the fitting alone.
