About the Airtac PGJ Plug Pin Reducing Straight Connector PGJ10-8
The PGJ10-8 is AirTAC's different diameter straight union from the PGJ plug-in reducer family: a fully push-in, thread-free fitting that joins a Dia 10 mm tube on one side to a Dia 8 mm tube on the other. Because both ends are one-touch, there is no male thread to wrap, no sealant to dry, and no wrench to reach for - you simply push each tube home until it bottoms in the chuck, and the internal stainless spring gasket plus NBR O-ring seal around the tube wall. To release, press the POM release ring toward the body and pull the tube free.
This is a resin/brass profile fitting, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. Use only soft nylon or polyurethane tubing. The standard body colour is grey; ordering the D suffix changes the body to black on this series. Construction is POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring.

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 PGJ Plug Pin Reducing Straight Connector PGJ10-8 Is Used
Packaging machine trunk-to-actuator drop
Run a Dia 10 nylon trunk along the frame of a flow-wrapper and drop to Dia 8 urethane line at each gripper cylinder, with PGJ10-8 making the step inline without tools.
Vacuum ejector feed step-down
Feed a compact vacuum ejector on a pick-and-place head with Dia 8 tube where the supply arrives as Dia 10, keeping the fitting weight and envelope small on the moving gantry.
Plating-line signal and actuation air
Where copper-free plumbing matters near chemical baths, route the resin-body PGJ10-8 in the dry zone to step a Dia 10 header down to Dia 8 lines serving panel valves.
Is the Airtac PGJ Plug Pin Reducing Straight Connector PGJ10-8 the Right Part?
Step down with PGJ8-6 to join a Dia 8 trunk to a Dia 6 drop, or step up with PGJ12-10 when your feed line is Dia 12 and the branch is Dia 10 - those are the neighbours on this ladder. Every step down narrows the bore, so air speed through the fitting rises and capacity falls relative to the larger tube; size the reduction to what the downstream actuator actually consumes rather than stepping down speculatively.
Both chucks are exact-OD fits: the Dia 10 end will not grip 12 mm tube and the Dia 8 end will not grip 6 mm tube, so check both line sizes before ordering. If what you actually need is a threaded step from a manifold port, use a threaded reducer such as PKD instead - PGJ has no port thread at all, which is precisely why it never needs thread sealant.
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 PGJ Plug Pin Reducing Straight Connector PGJ10-8 FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa and working temperature -20 to +70 C. The fitting joins Dia 10 mm tube to Dia 8 mm tube, both push-in, with no thread. Applicable tubing is soft nylon or polyurethane only, and at the top of the temperature range the tube, not the fitting, is the limiting factor.
No. PGJ is a tube-to-tube union with no port thread anywhere, so there is nothing to seal with tape - AirTAC ships threaded one-touch parts with pre-applied sealant, but this union is all push-in. Cut both tubes square, deburr the ends, push each fully home, and check the release ring has re-seated before pressurising.
