About the Airtac PGJ Plug Pin Reducing Straight Connector PGJ10-8D
The PGJ10-8D is AirTAC's plug-in reducer, a tube-to-tube union that joins a Dia 10 mm line on one side to a Dia 8 mm line on the other. Unlike every male or female connector in the range, it has no threaded stud at all: both ends are one-touch sockets, so the reduction happens without a threaded joint, without thread sealant and without the extra leak path a stud introduces. The D suffix gives it a black body rather than the standard grey.
This is the resin one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a service temperature of -20 to +70 C. Push each tube firmly into its socket until it bottoms out - the stainless spring gasket and the POM chuck grip the OD - and press the release ring to free it again. Soft nylon or polyurethane tubing only, and each end must be exactly 10 mm and exactly 8 mm OD.

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 PGJ10-8D Is Used
Packaging machine cylinder feed
A 10 mm trunk feeding a packaging conveyor's gripper cylinders often needs to land on an 8 mm cylinder port. PGJ10-8D makes that step inline in the loom, with no stud to wind sealant onto and no extra hex to find space for behind the guarding.
Pick-and-place vacuum drop
On an end-of-arm suction tool, a 10 mm vacuum line descending to an 8 mm suction-cup branch is a common step. Rated to -750 mmHg, the fitting holds the reduced side under full vacuum without a threaded interface to draw air through.
Workshop air drop reduction
Where a workshop bench drop is plumbed in 10 mm polyurethane but the tool or air gun at the end runs on 8 mm hose, this reducer changes size once, at the point of use, and can be released and re-plumbed when the layout changes.
Is the Airtac PGJ Plug Pin Reducing Straight Connector PGJ10-8D the Right Part?
Step down or up one rung at a time in the PGJ ladder. The size below is the PGJ8-6, which takes an 8 mm feed down to 6 mm for small cylinders and pilot lines; the size above is the PGJ12-10, which carries a 12 mm trunk into a 10 mm branch. Each step narrows the bore, so flow falls with it - if your actuator is starving, step back up rather than adding fittings. If you actually need to break into a threaded port, a PC male connector paired with a PG union does a different job; PGJ exists precisely so you can avoid that joint.
Match the sizes to the tubing, never to a nominal conversion: a Dia 8 socket will not hold 5/16 inch or 1/4 inch tube, and a Dia 10 socket will not hold 3/8 inch. OD is the only measure that matters.
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 PGJ10-8D FAQ
It is a plug-in reducer joining Dia 10 mm tube to Dia 8 mm tube, with no threaded port. Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Body is black (D suffix) resin with a POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring. Use soft nylon or polyurethane tubing.
Not with this part on its own - both PGJ ends are tube sockets, so the 8 mm side must end in 8 mm tube or in another fitting that accepts 8 mm tube. If you need the reduction to happen at a threaded port instead, step to a threaded reducer such as the PKD branch family or pair a PC male connector with a PG different-diameter union. Keep the reduction as a pure tube joint wherever you can: fewer threads means fewer sealant joints to maintain.
