About the Airtac PKD Reducing Thread 5-Way Fitting PKD8-602D
The PKD8-602D is an AirTAC male reducer triple branch, a one-touch fitting that turns a single 1/4in PT male port into three push-in outlets: one Dia 8mm line running straight through and two Dia 6mm branches set at 90 degrees. You push each soft nylon or polyurethane tube into its chuck until it bottoms out, the stainless spring gasket and grip ring hold it against pressure, and pressing the POM release ring frees it again. The thread arrives with sealant already applied, so it seals straight into a PT port without extra tape.
This is the black D-suffix build, where the body colour changes on the PKD series rather than just the button. It runs on the resin and brass spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. Worth knowing before you plan spares: AirTAC makes exactly three PKD sizes - PKD6-401, PKD8-602 and PKD10-803 - so this is the middle rung of a very short ladder, not one step in a long family tree.

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 PKD8-602D Is Used
Pick-and-place gripper feed
On a robotic pick-and-place cell, the 1/4in thread lands on the valve manifold outlet while the Dia 8 through line supplies the air and one Dia 6 branch feeds a compact gripper, all from one push-in point at the wrist.
Packaging machine vacuum branch
A rotary cup-filling machine can take Dia 8 mains from the FRL to each station and use the Dia 6 branch of this fitting to feed a small vacuum ejector, avoiding a separate tee and reducer in the crowded carousel wiring.
Manifold drop to two actuators
Where a control cabinet sits close to the actuators, the 1/4in male thread screws into the solenoid manifold and the two Dia 6 branches run out to a small bore cylinder and a pilot line, halving the fitting count on the drop.
Is the Airtac PKD Reducing Thread 5-Way Fitting PKD8-602D the Right Part?
PKD8-602D sits in the middle of the PKD range. Step down to PKD6-401 and you get a Dia 6 main with Dia 4 branches on a 1/8in thread - lighter lines, smaller ports. Step up to PKD10-803 and you move to Dia 10 main with Dia 8 branches on a 3/8in thread for higher-capacity circuits. There is nothing between these three part numbers, and there is no Dia 8 with a 1/2in thread or any other variant in this catalogue.
Match the 1/4in male thread to your manifold or valve port and remember PT is the only thread standard documented here - no G or NPT version exists. The tube rule is absolute: the through port grips Dia 8mm tube only and the two side branches grip Dia 6mm only, so a 5/16in or 1/4in tube will not seat. If you need a plain equal-size split instead of a reduction, the PE union tee is the shape to compare against.
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 PKD8-602D FAQ
This is a resin and brass one-touch male reducer triple branch for Dia 8mm through tube and Dia 6mm branches, with a 1/4in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. It suits soft nylon or polyurethane tubing, and the D suffix gives it the black body build.
No. The through port accepts only Dia 8mm tube and each side branch accepts only Dia 6mm - the reduction is built into the body, so a Dia 8 tube will not seal in a branch. If your circuit needs three equal outlets, look at the PE union tee instead; if you need smaller or larger reductions, PKD6-401 and PKD10-803 are the only other PKD variants AirTAC manufactures.
