About the Airtac PYB Y-Type Threaded Tee Fitting PYB601
The AirTAC PYB601 is a resin one-touch branch Y: a male 1/8in PT stud on one end and two Dia 6 push-in outlets angled off a common trunk, so a single threaded port can feed two tube runs without a separate tee body. Push each tube squarely into its chuck until it bottoms out and the stainless spring gasket grips it; press the release ring to let it go.
This is the resin/brass spec profile, not the metal BPC line: 0 to 1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C with soft nylon or polyurethane tube. The stud arrives with sealant already applied, and the 1/8in size takes an M5-style gasket-free thread rather than a separate sealing washer.

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 PYB601 Is Used
Small-parts assembly press
Feed two Dia 6 lines from one 1/8in manifold port to a pair of compact air cylinders that clamp PCB-style components on a benchtop press, halving the ports you need on the manifold.
Lab blow-off station
Split a single regulated 1/8in feed into two Dia 6 branches serving air nozzles that clear chips and dust from a microscope stage or inspection jig.
Packaging machine diverters
Drive two small diverter or pusher cylinders on a cartoning line from one solenoid outlet, keeping the pneumatic plumbing inside tight machine guarding.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB601 the Right Part?
On the PYB ladder with a 1/8in thread, Dia 6 sits between PYB401 (Dia 4) and PYB801 (Dia 8). Stepping down to Dia 4 buys a slimmer branch for compact actuators and thinner tubing runs; stepping up to Dia 8 doubles the bore area roughly four-fold, which matters when both branches feed cylinders rather than signal lines. If your port is 1/4in instead, PYB602 keeps the same Dia 6 tube and opens the ladder up to Dia 12 branches.
Both outlets take exactly Dia 6 tube - a 1/4in (6.35 mm) tube will seat loosely and weep under pressure, so match the OD exactly. If you need the two branches to feed different bore sizes, the different-diameter PYW union Y is the correct shape, not a PYB.
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 PYB601 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. This SKU joins Dia 6 tube to a 1/8in PT male stud, with two Dia 6 push-in outlets. AirTAC publishes flow for these fittings as a characteristic curve only, so capacity should be judged from the Dia 6 bore, not a quoted flow number.
Yes. The resin one-touch profile is rated to -750 mmHg (10 Torr), so the same fitting can sit on a suction branch for pick-and-place cups. Keep in mind the stud thread is PT and arrives with sealant applied; on vacuum lines an unsealed parallel thread can leak inward, so verify the port itself is tapered or use a gasketed interface.
