About the Airtac PC Threaded Straight Connector PC601D
The PC601D is an AirTAC PC male connector from the resin one-touch family: a Dia 6 mm push-in socket on one end and a male 1/8 in PT thread on the other. Push the tubing home and the stainless spring gasket plus the POM chuck clamp it against pressure; press the release ring and the tube slides straight back out. The D suffix here changes the release button to black - on PC series the body itself stays the same, unlike on most other prefixes where D recolours the whole fitting.
This part belongs to the resin and brass profile, not the metal BPC 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 working temperature of -20 to +70 C. The body is brass, the threaded stud arrives with sealant already applied, and it runs on soft nylon or polyurethane tube of exactly 6 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 PC Threaded Straight Connector PC601D Is Used
Compact labelling head feed
A 6 mm line feeding the air cylinder of a labelling or marking head, where the straight connector screws directly into the valve or cylinder port behind a tight guard and the black button stays easy to find against dark machine frames.
Valve manifold drop
Screwed into a 1/8 in PT outlet on a solenoid valve manifold, it hands off to a Dia 6 nylon run serving a small gripper or blow-off nozzle on an electronics assembly cell.
Pneumatic cabinet pilot line
Inside a control cabinet, a short Dia 6 polyurethane jumper from a pilot valve to a pressure switch, where the brass stud with pre-applied sealant seats into the component port without extra tape or paste.
Is the Airtac PC Threaded Straight Connector PC601D the Right Part?
On the thread side, 1/8 in is the smallest machine thread in the PC ladder, so the only step down is the M5 version, PC6M5, which seals with a gasket rather than thread sealant - useful on valve manifolds with shallow M5 ports. Step up to PC602 for a 1/4 in port. For the tube, PC401 (Dia 4) suits slim pick-and-place lines while PC801 (Dia 8) carries noticeably more flow to larger actuators; every 1/8 in PC part accepts tube from 4 to 12 mm, so the thread never forces you to change tube size.
Match the OD exactly: a Dia 6 socket will neither grip 1/4 in tube nor seal on 6.35 mm imperial hose. If your run needs a turn at the port, the PL male elbow replaces this straight fitting without re-plumbing.
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 PC Threaded Straight Connector PC601D FAQ
It joins Dia 6 mm tube to a male 1/8 in PT thread. 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. It is the resin and brass one-touch profile, takes soft nylon or polyurethane tube, and the D suffix makes the release button black while the brass body stays standard grey.
No. AirTAC ships the threaded stud with sealant already applied, so it can go straight into a PT port. The exception in this catalogue is M5: those sizes use a sealing gasket instead of sealant. Keep the pre-coated thread out of compounds that attack it, and remember the tube must be a true 6 mm OD - the chuck cannot compensate for off-size or oval tube.
