About the Airtac PYB Y-Type Threaded Tee Fitting PYB802-S
The PYB802-S is an AirTAC PYB branch Y one-touch fitting in the SUS304 -S execution. It takes one incoming Dia 8 mm soft nylon or polyurethane tube and splits the feed into two Dia 8 mm branch legs, all secured by a single 1/4in PT male thread. Push each tube into its port until it bottoms; the stainless spring gasket and chuck inside grip it, and the release ring frees it again without tools.
Because this is the -S variant, the threaded stud is SUS304 stainless steel while the body remains AirTAC's standard PBT - do not treat the whole fitting as solid stainless. Ratings are identical to the grey standard part: 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure, and -20 to +70 C. The 1/4in thread arrives with sealant applied.

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 PYB802-S Is Used
Twin grippers from one feed
On a pick-and-place robot arm, one 1/4in branch feeding two pneumatic grippers: the PYB802-S splits the Dia 8 supply line right at the end of the arm, halving the fittings needed versus a tee plus elbows.
Paired air knives on a bottling line
Splitting a single Dia 8 supply into two equal legs that drive the drying nozzles either side of a bottle conveyor, keeping both nozzles fed from one regulated drop.
Two vacuum ejectors, one supply
Where a lab-scale vacuum handling station runs two small ejectors from a shared 1/4in drop, the Y joins both ejector supply lines cleanly at the manifold without a clutter of threaded tees.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB802-S the Right Part?
On the PYB ladder with a 1/4in thread, Dia 8 sits between Dia 6 (PYB602) and Dia 10 (PYB1002). Stepping down to Dia 6 lightens the joints and suits shorter branch runs on smaller actuators; stepping up to Dia 10 reduces pressure drop when the two branch legs feedhungrier consumers. Remember tube OD must match exactly - a Dia 8 Y will not seal on 5/16in or 1/4in imperial tube, only on true 8 mm OD soft nylon or polyurethane.
Choose the Y shape when a single supply point must feed two destinations without adding a separate tee and elbow: the fixed Y geometry joins the two legs at an angle, which shortens plumbing compared with building the branch from individual fittings.
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 PYB802-S FAQ
It is a PYB branch Y one-touch fitting for Dia 8 mm soft nylon or polyurethane tube on all three ports, with a 1/4in PT male thread. 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. In the -S version the threaded stud is SUS304; the body remains PBT.
No. On the PYB family, -S means the threaded stud is upgraded to SUS304 stainless steel; the Y body is still the standard PBT material. Pressure, vacuum and temperature ratings are unchanged from the standard grey PYB802, and the dimensions are the same, so it is a direct substitute where a corrosion-resistant stud at the port is what matters.
