About the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5D-S
The PYB6M5D-S is an AirTAC branch Y one-touch fitting in the black-body finish with a SUS304 stud. It screws an M5x0.8 male thread into a small port and splits the supply into two Dia 6 mm tube lines at a fixed Y angle, so one outlet feeds two actuators without adding a separate tee. Push each tube home and the internal chuck grips it; press the POM release ring to free it. Unlike the larger threaded sizes, which arrive with sealant on the thread, M5 ports seal with a gasket, so do not add tape or paste to this stud.
This is the standard resin/brass spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. On this -S variant the stud is SUS304 while the body stays PBT, and the internals are unchanged - POM button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring. The corrosion benefit sits at the thread engagement and any exposed stud face, not the whole body.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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-S Is Used
Twin vacuum jets on an electronics test bench
An M5 port on a small ejector manifold splits through the Y into two Dia 6 lines feeding a pair of pickup nozzles, keeping both nozzles on a single valve output.
Dual cooling-air jets on a small CNC lathe
One M5 outlet on the machine's air block branches to two Dia 6 nozzles aimed at the cutting zone, clearing chips from both faces of the workpiece.
Pilot feed to two kickers on a carton packer
A single M5 pilot output drives two Dia 6 single-acting kick cylinders from one Y, halving the number of valve ports needed on the manifold plate.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5D-S the Right Part?
On the PYB M5 ladder only Dia 4 and Dia 6 exist, so this is the top of the M5 range. Step down to PYB4M5 if your tubing is Dia 4; there is no Dia 8 on M5. If you need more bore, move to PYB601 (Dia 6 on a 1/8 inch thread), which also opens Dia 8 and 10 options. Match the thread to the port first: M5x0.8 is the small valve and sensor manifold standard, and a Dia 6 one-touch chuck will not hold 1/4 inch (6.35 mm) tube - the outside diameter must match exactly.
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-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It accepts Dia 6 mm soft nylon or polyurethane tube on both legs and has an M5x0.8 male thread on PT standard, sealed by a gasket rather than thread sealant.
No. On PYB-type fittings the -S makes the male stud SUS304; the body remains PBT, black on this D-suffixed version. Ratings, tube ladders and dimensions are identical to the standard PYB6M5, so you gain corrosion resistance at the threaded joint without any re-rating or re-design of the machine.
