About the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5D
The PYB6M5D is an AirTAC PYB branch Y, the resin one-touch fitting that divides a single airline into two outlet legs set at a fixed Y angle. This version carries Dia 6 mm soft nylon or polyurethane tube on all three legs and screws into an M5x0.8 tapped port. The D suffix makes the PBT body black instead of the standard grey, which helps colour-code circuits or match dark machine enclosures.
Installation is push-in: seat the tube fully and the stainless spring gasket and chuck grip it against the aluminium-alloy guide; press the POM release ring to free it. Because the thread is M5, sealing comes from a gasket rather than the sealant pre-applied to larger PT threads, so this stud goes in clean and dry. It runs on the resin spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C.

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 PYB6M5D Is Used
Mini valve manifold feeds
Screws straight into the M5 outlet of a compact pneumatic valve manifold, then splits the Dia 6 line to a small cylinder and its reed-switch-side pilot circuit without adding a second valve.
Laboratory dispensing heads
On bench-top liquid-handling and dispensing stations, one M5 supply from the controller splits to twin Dia 6 legs driving two ejector heads in sync, and the gasket seal keeps sealant particles out of clean tubing runs.
Compact gripper plumbing
On small parallel grippers with M5 ports on both jaws, a single feed enters the Y stem and two short Dia 6 polyurethane legs reach each actuator port inside a tight end-of-arm tooling envelope.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5D the Right Part?
On the M5 ladder for PYB, Dia 6 is the top of the range: only Dia 4 and Dia 6 exist below it, so the smaller neighbour is the PYB4M5, which suits micro actuators and thinner polyurethane runs. There is no larger M5 option at all. To feed bigger bores you change thread family, stepping to the PYB801 (Dia 8 tube on a 1/8in thread), which trades the compact gasket-sealed M5 stud for a sealant-sealed PT taper.
Choose a Y when one supply has to feed two legs, such as a pair of single-acting cylinders or a gripper and its pilot line. Match the tube exactly: a Dia 6 chuck will not hold 1/4in (6.35 mm) tube even though the two look close, and a mismatched OD leaks or blows off under pressure.
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 PYB6M5D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. It accepts Dia 6 mm soft nylon or polyurethane tube on all three legs and has an M5x0.8 male stud sealed by a gasket. The black body is PBT with a brass stud, POM release ring and chuck, aluminium-alloy guide and stainless spring gasket.
No. Unlike the larger PT-threaded PYB sizes, which arrive with sealant pre-applied, M5x0.8 studs on this series seal with a gasket. Wrapping tape on an M5 thread can shed fragments into the airline and may stop the stud seating square against its port face, so fit it clean and torque only enough to compress the gasket.
