About the Airtac PHD Swivel Reducing Hex Port Connector PHD8-6
The PHD8-6 is an AirTAC PHD universal reducer four branch union: a thread-free cross-shaped fitting that joins four tube lines in one body and steps the bore down from Dia 8 to Dia 6. Push an 8 mm soft nylon or polyurethane tube into the supply leg and 6 mm tubes into the branch legs; inside each port, a stainless spring gasket and the chuck jaws close around the tube wall to grip and seal it. Press the release ring toward the body and the tube slides straight out.
This is a resin one-touch part, so it runs on the 0 to 1.0 MPa (0 to 10 kgf/cm2) pressure profile with a 1.5 MPa proof pressure and handles vacuum down to -750 mmHg (10 Torr). It works from -20 to +70 C. The body is PBT with a POM release button and chuck, an aluminium-alloy guide and an NBR O-ring, and the grey body is the standard finish. Because there is no threaded stud, nothing needs sealant or a sealing washer - every joint is tube-on-tube.

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 PHD Swivel Reducing Hex Port Connector PHD8-6 Is Used
Robot gripper air distribution
On a 3- or 4-finger pneumatic gripper cell, run Dia 8 tube from the valve manifold to the wrist and split it at the PHD8-6 into three Dia 6 drops - one per finger actuator - without a single threaded joint in the moving arm.
Conveyor blast and cleaning nozzles
A packaging line conveyor that carries air-knife or cleaning nozzles along its length can tap the Dia 8 trunk line with this cross and feed three Dia 6 nozzle legs, keeping the under-belt plumbing flat and low-profile.
Lab automation reagent handling
Benchtop liquid-handling and microplate machines often combine one larger Dia 8 purge or exhaust line with several Dia 6 actuator lines; a single PHD8-6 cross at the manifold wall keeps that routing reversible when the tubing layout is reworked.
Is the Airtac PHD Swivel Reducing Hex Port Connector PHD8-6 the Right Part?
In the PHD reducer ladder the step below this part is PHD6-4, which drops a Dia 6 main to Dia 4 branches for small actuators and sensing lines; the step above is PHD10-8, which takes a Dia 10 main down to Dia 8 branches for higher-flow headers. What changes as you step is the branch capacity: smaller branches mean less air per leg, so keep PHD8-6 for Dia 8 mains feeding two or three Dia 6 actuators of moderate size.
Before ordering, confirm every tube is metric and matches the port exactly - a Dia 8 port will not seal on 5/16 inch tube, and a Dia 6 port will not hold 1/4 inch (6.35 mm). If your supply comes from a threaded port rather than a tube run, a PKD male reducer triple branch is the threaded cousin of this shape; PHD8-6 is the right answer only when the source is itself a Dia 8 tube.
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 PHD Swivel Reducing Hex Port Connector PHD8-6 FAQ
The PHD8-6 is a resin one-touch universal reducer four branch union joining Dia 8 tubing on one side to Dia 6 tubing on the other three. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure is 1.5 MPa, and vacuum capability is -750 mmHg (10 Torr). The operating temperature range is -20 to +70 C and the tubing must be soft nylon or polyurethane. There is no threaded port - all four connections are push-in tube ports on the PT-standard resin profile.
Push the tube fully home until it bottoms, then it is gripped by the internal chuck. To release, press and hold the POM release ring square against the body while pulling the tube out with a steady pull - never lever it sideways. The fitting can be opened and re-made as many times as the tube end stays round and unscratched, though AirTAC publishes no specific release cycle count. Cut a fresh square tube end if the old one shows grip marks before reconnecting.
