About the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5-S
The PYB6M5-S is an AirTAC PYB branch Y one-touch fitting that takes a single Dia 6 mm tube and splits the flow into two 6 mm branches, all mounted on an M5x0.8 male stud. Push each tube straight into its port and the internal chuck grips it; press the release ring and the tube frees again. The Y geometry sends the supply into two diverging legs rather than keeping one straight-through path, which is what separates it from a run tee.
This is the -S stainless variant. For the PYB family that means the M5 stud is stainless steel 304 while the body stays PBT; it is not a solid stainless part, and the pressure figures are unchanged. The resin profile applies: 0-1.0 MPa working, -750 mmHg vacuum, 1.5 MPa proof, -20 to +70 C. Unlike the larger threaded sizes, the M5 stud arrives with a sealing gasket rather than pre-applied thread sealant, so the soft seal does the work at the port.

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 PYB6M5-S Is Used
Benchtop pilot rig plumbing
A laboratory gas or instrument-air skid with M5-tapped manifold ports can feed two 6 mm sample or purge lines from one outlet, halving the fitting count at the splitter point.
Compact pick-and-place head
A small gripper or feeder running two 6 mm mini cylinders off a single valve outlet keeps the plumbing to one M5 connection at the valve and one Y in the harness.
Electronics test fixture air feed
A PCB test or cooling fixture with M5 pneumatic ports splits one regulated feed into two 6 mm nozzle lines, and the SUS304 stud suits fixtures that get wiped down or see mild corrosion exposure.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB6M5-S the Right Part?
On the M5 row of the PYB ladder, Dia 6 is the top of the range: Dia 4 (PYB4M5-S) is the only smaller step and there is no larger M5 size, so anything above Dia 6 means moving the thread to 1/8 inch, where Dia 8 and Dia 10 open up. Match the M5 port to small pilot outlets and compact valve manifolds; if the port is 1/8 inch PT, this part will not seat and a PYB6-01 is the correct code.
Tube OD must match exactly. A Dia 6 fitting will not hold 1/4 inch nominal tube, which measures about 6.35 mm, and it will not grip 8 mm. Check the number printed on the tubing wall before ordering either way.
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-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting accepts Dia 6 mm soft nylon or polyurethane tube on all three ports and mounts on an M5x0.8 male stud.
No. On the PYB series the -S makes the M5 stud SUS304; the body remains PBT, exactly as on the standard part. The pressure, vacuum and temperature figures are identical, so do not expect a re-rating. What you gain is a corrosion-resistant stud where the fitting meets the machine port, which matters on fixtures washed down or exposed to mild chemicals.
