About the Airtac PHD Swivel Reducing Hex Port Connector PHD10-8
The PHD10-8 is an AirTAC PHD universal reducer four branch union, a tube-to-tube cross that joins four push-in lines while stepping the bore from Dia 10 down to Dia 8. Push each soft nylon or polyurethane tube into its port until it bottoms: an internal stainless spring gasket and POM chuck grip the tube wall, and the POM release button frees it again when you need to re-route. No thread, no sealant, no wrench.
This is a resin-line part, so the figures are the 0-1.0 MPa (0-10 kgf/cm2) working pressure profile, not the lower 0.9 MPa metal line. Proof pressure is 1.5 MPa, vacuum service runs to -750 mmHg (10 Torr), and the temperature window is -20 to +70 C. Sealing is by NBR O-ring throughout, which is why the catalogue pairs it with soft nylon and polyurethane tubing only.

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 PHD10-8 Is Used
Assembly cell drop manifold
Mount the PHD10-8 at the head of a Dia 10 trunk drop from the FRL and feed four Dia 8 lines to grippers and small cylinders on a single fixture plate, eliminating four separate reducer fittings.
Vacuum ejector distribution
The -750 mmHg (10 Torr) rating lets this cross sit on the suction side of a compact ejector array, splitting one Dia 10 vacuum line into Dia 8 legs running to suction cups on a palletising head.
Lab automation reagent handling
On a benchtop dispensing rig the four-way union lets a Dia 10 supply feed Dia 8 tubing drops to peristaltic or pinch-valve stations, and the push-to-release buttons make re-plumbing a new assay layout a tool-free job.
Is the Airtac PHD Swivel Reducing Hex Port Connector PHD10-8 the Right Part?
On the PHD reducer ladder the neighbour below is PHD8-6, which steps an 8 mm trunk down to 6 mm branches - the right choice once your drop lines get short and your flow demand is light. Above it sits PHD12-10, which keeps a 12 mm main intact and steps to 10 mm take-offs instead. Pick PHD10-8 when your trunk is Dia 10 and your four outlets feed Dia 8 actuators or sub-lines; going one step either way changes branch bore and therefore how much the cross throttles a shared supply.
Because this union has no thread at all, there is nothing to match to a port - the discipline here is tube matching. Every port takes its stated OD and nothing else: a Dia 8 port will not hold 1/4 inch (6.35 mm) tube even though the numbers look close, and the grip will weep if you force it.
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 PHD10-8 FAQ
It is a Dia 10 to Dia 8 universal reducer four branch union (four push-in ports, no thread). Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Applicable tubing is soft nylon or polyurethane. This is the resin spec profile - the 0.9 MPa / 150 C figures belong to AirTAC's metal BPC family, not this part.
There is no threaded port, so no sealant is ever needed on this fitting. The two port sizes are fixed by the code: Dia 10 legs and Dia 8 legs, so plan your layout so each 10 mm run reaches a 10 mm port. The universal construction lets the union body be oriented so the branch directions suit the machine - tube can enter from any port side once the cross is positioned, and any tube can be pulled out with the release button if the routing changes.
