About the Airtac PP Pipe Plug PP6
The AirTAC PP6 is a one-touch straight union, the simplest member of AirTAC's tube-to-tube resin fitting range. It has no thread at all: both ports are Dia 6 mm tube sockets, so its only job is to splice two lengths of 6 mm soft nylon or polyurethane tubing into one continuous, straight run. Push the tube home and the internal chuck grips the OD; press the POM release ring and the tube slides straight back out.
Because PP6 belongs to the resin/brass one-touch profile, it is rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, 1.5 MPa proof, and -20 to +70 C, and it also holds -750 mmHg (10 Torr) on vacuum lines. The body is moulded resin with a POM release button and an NBR seal; no thread means no sealant, tape or gasket anywhere on this part.

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 PP Pipe Plug PP6 Is Used
Pick-and-place gripper line splice
On a benchtop pick-and-place arm, a 6 mm PU feed line that runs short is easiest extended by pushing both cut ends into a PP6 union rather than re-plumbing back to the valve manifold.
Vacuum suction line repair
A cracked run of 6 mm tubing feeding a suction-cup manifold on a small PCB handling cell can be spliced with PP6 because the union holds -750 mmHg (10 Torr) without leaking.
FRL outlet to flow-control valve
On a packaging machine's air prep branch, PP6 joins the 6 mm nylon drop from the filter-regulator outlet to the inlet side of an inline flow-control valve in a straight, serviceable link.
Is the Airtac PP Pipe Plug PP6 the Right Part?
Step down to PU4 or up to PU8 to follow your tube ladder - the fitting grows with the bore, so an 8 mm union simply moves more air per metre of run. If the line itself narrows from 6 mm to 4 mm, keep the splice single-piece by using the PG6-4 different-diameter straight instead of two unions and an adapter. On a vacuum leg, remember PP6 is rated to -750 mmHg, so a suction-line splice does not force you onto a metal fitting.
Tube OD must match exactly: PP6 grips 6.0 mm tubing only. A 1/4 inch (6.35 mm) tube looks close but will not seat in the chuck, and a 6 mm union will not accept 8 mm tube no matter how hard it is pushed.
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 PP Pipe Plug PP6 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), temperature -20 to +70 C. Size: both ends accept 6 mm OD soft nylon or polyurethane tube; there is no threaded port on this part. Release button and chuck are POM, the seal is NBR.
No. A straight union grips one OD on both sides, so PP6 is 6 mm to 6 mm only. For a change of bore in one part use the AirTAC PG different-diameter straight (for example PG6-4 or PG8-6), which keeps the same one-touch push-in action.
