About the Airtac PKD Reducing Thread 5-Way Fitting PKD8-602
The AirTAC PKD8-602 is a male reducer triple branch, a one-touch fitting that combines a tee and a size reducer in a single brass-bodied part. A 1/4in PT male stud screws into the port, the Dia 8 run continues straight through the body, and a Dia 6 branch leaves at 90 degrees. Pushing soft nylon or PU tubing home past the stainless spring gasket seats it in the POM chuck, which grips the tube on pressure; pressing the release ring frees it again.
This is the resin and brass one-touch profile, not the metal BPC line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. The PT stud arrives with sealant already applied, so no tape is needed on the port. Reducing inside the fitting instead of adding a separate tee plus a reducer removes one joint and one potential leak point from the branch.

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 PKD8-602 Is Used
Manifold branch on a packaging machine
A valve manifold on a form-fill-seal machine runs Dia 8 tube along the valve bank; the PKD8-602 branches off in Dia 6 to feed a small bag-clamp cylinder without an extra reducer joint.
Pick-and-place gripper feed
On an electronics pick-and-place cell, the Dia 8 vacuum-ejector supply line branches through the PKD8-602 down to Dia 6 tubing routed to a compact gripper block inside the gantry.
Conveyor reject-gate takeoff
A bottle-line inspection station taps Dia 6 air for its reject pusher off the Dia 8 conveyor-gate supply run, using the 1/4in PT stud to land directly on the solenoid valve outlet.
Is the Airtac PKD Reducing Thread 5-Way Fitting PKD8-602 the Right Part?
PKD is a deliberately short ladder: AirTAC makes exactly three sizes, PKD6-401, this PKD8-602 and PKD10-803. Stepping down to PKD6-401 gives a Dia 6 run with a Dia 4 branch on a 1/8in stud, suited to smaller signal or pilot lines; stepping up to PKD10-803 gives a Dia 10 run with a Dia 8 branch and a 3/8in stud for larger main feeds. If your branch does not need a reduced bore, a standard PED male run tee in matching sizes is the simpler choice.
Match the 1/4in PT stud to ports threaded PT 1/4, and remember the tube side is unforgiving on OD: the Dia 6 branch accepts Dia 6 tubing only and will not hold 1/4in or 5/16in imperial tube, however close it looks. The Dia 8 run is likewise Dia 8 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 PKD8-602 FAQ
The PKD8-602 is a male reducer triple branch with a Dia 8 mm straight run, a Dia 6 mm branch and a 1/4in PT male stud. It is the resin and brass one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and an operating temperature of -20 to +70 C. It accepts soft nylon or polyurethane tubing only, and the stud ships with sealant pre-applied.
No. AirTAC produces only three PKD variants: PKD6-401 (Dia 6 run, Dia 4 branch, 1/8in stud), PKD8-602 (this part, Dia 8 to Dia 6, 1/4in stud) and PKD10-803 (Dia 10 to Dia 8, 3/8in stud). For any other run/branch combination you would need a PED male run tee plus a PG different-diameter straight union, or a PKG reducer triple branch union, which is the threaded-free tube-to-tube equivalent.
