About the Airtac PYB Y-Type Threaded Tee Fitting PYB603D-S
The AirTAC PYB603D-S is a one-touch branch Y fitting that takes a single 3/8in PT male thread and splits the supply into two Dia 6 mm tube lines angled away from each other. Push each tube into its chuck until it bottoms out and the stainless spring gasket and grip ring hold it under pressure; press the POM release ring and the tube slides free again. The D suffix gives this version a black body rather than the standard grey.
This is a resin-profile part: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and a -20 to +70 C window, running soft nylon or polyurethane tube. The -S variant fits a SUS304 stud into the thread, which is where splash and wash-down attack first; the body itself stays PBT on this family, unlike the PC and POC straight connectors whose whole body becomes stainless 304. The 3/8in thread arrives with sealant already applied, so it seals on the PT taper straight out of the bag.

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 PYB603D-S Is Used
Twin-gripper pick-and-place head
On a carton erecting or case-packing machine, one 3/8in valve output on the gantry can split into two Dia 6 lines running to a pair of suction-cup ejectors, with the Y body sitting inside the guarding where a rigid tee would need extra bends.
Commercial car-wash gantry
The SUS304 stud shrugs off the constant detergent splash that corrodes a plain brass thread at the manifold, while the black PBT body hides grime on the spray-frame air feeds to the oscillating nozzle actuators.
Electroplating line actuator feed
Acid mist rising from a plating tank attacks exposed brass fast; fitting this Y with its stainless stud at the valve branch feeding two lift or transfer cylinders keeps the most vulnerable metal out of the fume path.
Is the Airtac PYB Y-Type Threaded Tee Fitting PYB603D-S the Right Part?
Both neighbours exist on the PYB ladder: PYB602 keeps the same Dia 6 tube but steps the male thread down to 1/4in, which is the usual choice when your valve island or manifold port is the smaller size, and PYB803 keeps the 3/8in thread but takes Dia 8 tube, adding bore where a longer or hungrier branch needs it. Note that stepping the tube down to Dia 4 on a PYB is only offered up to a 1/4in thread - AirTAC makes no Dia 4 branch Y with a 3/8in port, so this SKU is effectively the smallest tube you can hang on a 3/8in Y.
Match the 3/8in thread to the port, not to the tube: the branch Y is exactly the shape to use when one valve output must feed two actuators without a separate tee. And whatever you order, the tube OD must match the fitting exactly - a Dia 6 chuck will not seal on 1/4in (6.35 mm) imperial tube, even though the two are close enough to fool the eye.
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 PYB603D-S FAQ
This branch Y joins Dia 6 mm tube to a 3/8in PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), it holds -750 mmHg (10 Torr) vacuum, proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. It runs soft nylon or polyurethane tube, and the -S suffix means the threaded stud is SUS304 stainless steel.
No. On the PYB family the body remains PBT and only the stud is SUS304, which protects the threaded connection in wash-down and corrosive air. Only the PC and POC straight connectors get a full stainless 304 body in the -S line. Note also that the ratings do not change with -S: this is still the 1.0 MPa / 70 C resin profile, not the 0.9 MPa / 150 C metal BPC line.
