About the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5
The PYB6M5 is an AirTAC PYB branch Y one-touch fitting: a single M5x0.8 male thread that splits into two Dia 6 mm tube ports set at a Y angle. Push each tube home and the internal chuck grips it; press the release ring to free it again. The M5 stud seals with a small gasket, so no thread sealant is needed - unlike the larger PT threads in this catalogue, which arrive with sealant pre-applied.
This is the resin/brass profile: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C with soft nylon or polyurethane tubing. The grey body pairs a POM chuck and release button with a brass stud and a PBT threaded portion. On the PYB ladder, the M5 thread is offered in Dia 4 and Dia 6 only, which makes this the largest tube size the M5 thread supports in this series.

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 PYB6M5 Is Used
Pick-and-place ejector split
On a compact vacuum pick-and-place gripper, one M5 ejector port feeds two Dia 6 suction lines through the PYB6M5, halving the plumbing runs inside a tight gripper body.
Pilot feed for twin mini cylinders
A labelling machine's M5 pilot valve output splits to two Dia 6 lines driving small advance cylinders, using a single port instead of a fabricated manifold block.
Bench fixture chip-cooling jets
On an electronics test bench, M5 ports on mini valves are scarce; a Y branch lets one M5 supply serve two Dia 6 air jets aimed at hot components for spot cooling.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5 the Right Part?
Stepping down, PYB4M5 serves Dia 4 tube where flow demand is light, such as pilot signals or sensor purge; stepping up from Dia 6 on this prefix means changing thread, because no Dia 8 PYB exists in M5 - PYB6-01 with a 1/8 in thread is the usual next step. Match the port carefully: many valves, sensors and ejectors use M5, and forcing the fitting into an untapped or oversized hole will leak at the gasket face. Always order the exact tube OD; a Dia 6 socket will not hold 6.35 mm (1/4 in) tube, which slips 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 PYB6M5 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2); vacuum down to -750 mmHg (10 Torr); proof pressure 1.5 MPa; temperature range -20 to +70 C. It joins Dia 6 mm soft nylon or polyurethane tube to an M5x0.8 male thread on a grey body, and sits in the PYB M5 ladder that covers Dia 4 and Dia 6 only.
No sealant: M5 sizes in this series seal with a small gasket on the stud face, and excess sealant can block the tiny M5 orifice. And no - the socket accepts Dia 6 mm OD tube only; 1/4 in (6.35 mm) tube is a different OD and will neither grip nor seal.
