About the Airtac PYB Y-Type Threaded Tee Fitting PYB1001-S
The PYB1001-S is an AirTAC PYB branch Y, a one-touch fitting that splits a single 10 mm tube supply into two lines, both gripped by the same push-in chuck. The male stud carries a 1/8in PT thread that arrives with sealant pre-applied, so it seals into the port on the first few turns. To connect, push the tube home until it seats; the stainless spring gasket and chuck grip it, and pressing the release ring frees it again.
This -S version keeps the PBT body of the standard PYB but the threaded stud is SUS304, so the connection into a corroded or stainless manifold stays sound where a plain brass stud would degrade. Ratings are unchanged from the standard resin line: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. Note that at -20 C the soft nylon or PU tubing is usually the first limit, not the fitting.

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 PYB1001-S Is Used
Twin-wash nozzles on a lab glassware washer
One 1/8in PT tap on the washer manifold splits through the SUS304 stud into two Dia 10 tube runs feeding parallel rinse nozzles, with the Y angle keeping the tubes routed flush along the cabinet wall instead of one hard 90 deg turn.
Corrosion-prone plating line actuator supply
On a pick-and-place arm above an acid plating bath, the SUS304 stud resists attack at the manifold port while the PBT body carries 0-1.0 MPa air to a single Dia 10 leg feeding two clamp cylinders.
Dual air knives on a bottle rinsing conveyor
A Dia 10 supply running the length of a rinse conveyor branches at the Y into two equal Dia 10 lines, one per air knife station, so both knives see a split of the same feed without extra fittings in the path.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB1001-S the Right Part?
On the PYB ladder at 1/8in PT, Dia 10 is the top of the rung: the next size down is Dia 8 (PYB801), and there is no Dia 12 in 1/8in. If you are feeding two Dia 10 lines from a manifold, step up to the same tube on a 1/4in thread (PYB1002) so the port has more thread engagement and the stud is stiffer. The Y angle is the point of this shape: it sends both branches along the tube run instead of at right angles, so no 90 deg bends in the tubing that rob effective bore and add stress on the push-in collar.
Check that both tube legs are exactly Dia 10; a 5/16in (7.9 mm) tube will slide in but the chuck cannot seal it reliably. For a run that has to turn rather than split, the PE union tee or PV union elbow is the wrong-shape check - the Y exists specifically for angled splits.
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 PYB1001-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), temperature -20 to +70 C. This SKU accepts Dia 10 mm tube on all three legs and a 1/8in PT male thread on the stud, which arrives with sealant. The stainless -S option makes the stud SUS304 while the body stays PBT; pressure and temperature figures are identical to the standard PYB1001.
No. Every one-touch port on this fitting is bored and gasketed for exactly Dia 10 mm soft nylon or polyurethane tube. An off-size tube can seat but the spring gasket cannot seal on the correct surface, which is the usual cause of a slow weep at a pushed-in joint. If you need Dia 8 or Dia 12 branches, use the PYB different-diameter union Y family or a PG reducer before the split.
