About the Airtac PKD Reducing Thread 5-Way Fitting PKD10-803
The PKD10-803 is AirTAC's male reducer triple branch: a 3/8in PT male stem that carries a Dia 10 tube straight through the run and feeds two reduced Dia 8 branch legs off the same port. It is the only part in the PKD ladder that steps down from a 10 mm run, so it turns one larger supply branch into two smaller circuits with a single screwed connection.
This belongs to the resin one-touch profile: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg vacuum and -20 to +70 C. Push the tube home and the stainless spring gasket plus chuck grip it; press the POM release ring to free it. The body is PBT on a brass stud, the thread arrives with sealant applied, and the sealing O-ring is NBR.

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 PKD Reducing Thread 5-Way Fitting PKD10-803 Is Used
Packaging machine manifold branch
A 3/8in PT outlet on a rotary packaging machine's manifold feeds a Dia 10 run; PKD10-803 splits it into two Dia 8 legs supplying twin vacuum ejector or gripper circuits without extra tees.
Blow-off station distribution
On a plastic injection mould side, the reduced Dia 8 branch legs carry air from the Dia 10 run out to two blow nozzles that clear finished parts from the cavity.
Conveyor cylinder feed splitting
A pusher or divert cylinder section on a belt conveyor line takes its Dia 8 actuator lines from one Dia 10 supply branch, keeping the piping count at a single fitting per drop.
Is the Airtac PKD Reducing Thread 5-Way Fitting PKD10-803 the Right Part?
AirTAC makes exactly three PKD parts, so there is no size above this one: PKD10-803 is the top of the ladder. The only step down is PKD8-602, which drops the run to Dia 8, the branches to Dia 6 and the thread to 1/4in - choose it when the supply branch is 8 mm and the port is a 1/4in boss. Step up in capacity instead by moving to a PED or PYB pattern if you need a bigger run than 10 mm. Tube OD must match exactly on every leg: the Dia 10 run will not grip 12 mm tube and the Dia 8 branches will not hold 3/8in tubing.
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 PKD Reducing Thread 5-Way Fitting PKD10-803 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), operating temperature -20 to +70 C. Size: Dia 10 run tube, Dia 8 branch tubes, 3/8in PT male thread. Resin one-touch construction with PBT body on a brass stud, POM release button and chuck, stainless spring gasket and NBR O-ring; applicable tubing is soft nylon or polyurethane.
AirTAC publishes just PKD6-401, PKD8-602 and PKD10-803 - one reducer triple branch per thread size. If your run tube is Dia 10 with a 3/8in port, PKD10-803 is the only correct code; there is no Dia 12 variant and no other thread in the family, so do not re-tap a port to fit a different PKD.
