About the Airtac PKD Reducing Thread 5-Way Fitting PKD10-803D
The PKD10-803D is an AirTAC male reducer triple branch, the only shape in the PKD family that turns one incoming line into two reduced outlets on a common axis. This part accepts Dia 10 mm soft nylon or polyurethane tube on the main leg and Dia 8 mm on both branches, and its 3/8in PT male stud screws straight into a port or manifold boss. The D suffix gives it the black body option, which on PKD changes the whole PBT shell, not just the release button as on the PC and POC connectors.
As a resin-line one-touch fitting it is rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. Push the Dia 10 tube home and the stainless chuck jaws grip it under the POM release ring; the Dia 8 branches connect the same way. The brass stud arrives with sealant already applied, and an NBR O-ring seals the tube against the fitting.

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 PKD10-803D Is Used
Injection mould clamp circuit
On a plastic injection machine, a Dia 10 supply drops to two Dia 8 branches feeding clamp actuators, all teeing off one 3/8in port on the valve manifold without extra elbows.
Cartoning machine vacuum assist
A packaging line cartoner uses the Dia 10 main leg for its header and the twin Dia 8 branches to feed two suction cup lines, keeping the plumbing on a single axis behind the guard.
Textile loom air distribution
In a weaving shed, the reducer branch splits a Dia 10 distribution run into Dia 8 drops for pneumatic thread tensioners, halving joint count versus a tee plus two reducers.
Is the Airtac PKD Reducing Thread 5-Way Fitting PKD10-803D the Right Part?
PKD exists as exactly three catalogue part numbers, and this is the largest of them. Step down to the PKD8-602 if your main run is Dia 8 with Dia 6 branches on a 1/4in stud; there is no step up, so if your main line is Dia 12 you need a different shape such as a PEB branch tee with a separate reducer. Drop PKD entirely and pick the PED male run tee if both outlets should stay at the same diameter as the supply.
Match the 3/8in PT thread to the port before anything else, because the tube ladders only exist in the sizes AirTAC paired with that thread. Above all, respect exact tube OD: the Dia 10 main leg will not seal on 3/8in (9.5 mm) imperial tube and the Dia 8 branches will not hold 5/16in, so metric tubing only.
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 PKD10-803D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg, proof pressure 1.5 MPa, temperature -20 to +70 C. Tube is Dia 10 mm on the main leg and Dia 8 mm on both branches, with a 3/8in PT male stud. It is the resin/brass one-touch profile, so do not run it above 70 C where the metal BPC family would be the correct choice.
No. AirTAC makes only three PKD part numbers: PKD6-401, PKD8-602 and this PKD10-803D, which is the end of the ladder. For a Dia 12 main line use a PEB or PED branch tee instead, and reduce to the branch size with a separate PG union reducer.
