About the Airtac PYB Y-Type Threaded Tee Fitting PYB802D
The PYB802D is an AirTAC PYB branch Y, a one-touch fitting that takes a single 1/4in PT threaded supply port and splits it into two Dia 8 mm tube branches. Where a tee runs at right angles, the Y body angles both branches off the stud, so the two downstream lines leave the fitting close together and can be routed along the same frame rail without a sharp bend in either tube. This D-suffix version has the black body colour rather than the standard grey.
Connection is push-to-connect: push each 8 mm tube firmly into a port until it bottoms, and the internal chuck grips the tube wall while the stainless spring gasket and NBR O-ring seal it; press the POM release ring toward the body and the tube slides free. As a resin-series part it is rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C, with soft nylon or polyurethane tubing. The threaded stud is brass with sealant pre-applied, so it seals onto the PT port without extra tape.

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 PYB802D Is Used
Twin cylinder feed on a pick-and-place gantry
One 1/4in valve output splits into two Dia 8 lines feeding the up and down gripper cylinders, with both tubes leaving the Y at a matched angle so the harness bends stay even through every stroke.
Packaging carousel product-blow nozzles
A single supply port on a rotary indexing table feeds two Dia 8 air nozzles that sweep empty cartons off the conveyor, the angled Y body keeping the pair of lines tight against the rotating frame.
Split feed on a lab skid purge panel
Inside a compact stainless instrument skid, one 1/4in PT bulkhead port serves two Dia 8 purge lines to separate chambers, and the black body keeps the plumbing visually consistent with dark panel hardware.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB802D the Right Part?
On the PYB 1/4in ladder this Dia 8 sits in the middle: PYB602 steps down to Dia 6 for lighter lines to small actuators or sensors, while PYB1002 steps up to Dia 10 when the two branches feed larger cylinders or longer runs that need more bore. Going up in tube size costs panel space around the body, so check the branch spacing before you commit. Thread-wise, 1/4in PT is the standard cylinder and valve port size, but if your port is 1/8in you would move to PYB801 instead - the tube stays Dia 8 across both.
Tube OD must match exactly: this fitting holds Dia 8 mm tube only and will not seal on 5/16in or 1/4in imperial tube, even though the thread is imperial-sized. If you actually need to reduce from a Dia 10 supply to two Dia 8 branches, a reducer-style branch such as the PKD triple branch is the better shape than this equal-bore Y.
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 PYB802D FAQ
It is a resin-series AirTAC PYB branch Y: working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It joins two Dia 8 mm tube branches to a 1/4in PT male thread, and takes soft nylon or polyurethane tubing only.
No. On the PYB series the D suffix changes the body to black; the pressure, vacuum, temperature and material ratings are identical to the grey PYB802. The one thing it does affect is availability of neighbouring sizes in that colour - on the 1/4in thread the PYB range runs from Dia 4 up to Dia 12, so PYB602 and PYB1002 are the steps either side of this one if you later need to resize the branches.
