About the Airtac PC Threaded Straight Connector PC603
The PC603 is an AirTAC PC series one-touch male connector: a straight fitting that turns a 3/8in PT male thread into a push-in socket for 6 mm outside diameter soft nylon or polyurethane tube. Push the tube home and the stainless spring gasket and chuck grip it against the POM seal; press the grey POM release button and the tube slides straight back out. The body on the PC series is brass, with a brass stud and PBT threaded components.
This is the resin one-touch spec, 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 temperature window of -20 to +70 C. The 3/8in thread arrives with sealant already applied, so no PTFE tape is needed on the port - only M5 sizes use a gasket instead.

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 PC603 Is Used
Packaging machine air drop
On a vertical form-fill-seal machine, the 3/8in manifold branch is bigger than the actuator needs; PC603 steps that port down to a 6 mm line feeding a small sealing jaw cylinder.
Valve manifold outlet
A 5/2 solenoid valve block on a bottling line with 3/8in outlets takes PC603 directly, pushing 6 mm tube out to grippers without adaptors or tape.
Pilot air to process valves
Pneumatically actuated butterfly and ball valves with 3/8in pilot ports in a water treatment skid take 6 mm control tubing straight from the PC603 socket.
Is the Airtac PC Threaded Straight Connector PC603 the Right Part?
On the PC ladder at 3/8in, Dia 6 is the smallest tube offered - PC603 is the bottom rung. Step up to PC803 (Dia 8 on the same 3/8in thread) for heavier air delivery to the same port. If your port is 1/4in instead, PC602 carries the same 6 mm tube on the smaller thread, and Dia 4 tube only exists on PC at the 1/8in and 1/4in threads (PC401, PC402).
Match the thread to the port drawing, not to the hose: the 3/8in stud is sealant-coated, so a clean tapped PT port seals hand-tight plus a modest wrench turn. And always match tube OD exactly - a Dia 6 socket will not hold 1/4in tube even though the numbers look close.
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 PC603 FAQ
It joins Dia 6 mm OD soft nylon or polyurethane tube to a 3/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure is 1.5 MPa, vacuum rating is -750 mmHg (10 Torr), and the working temperature range is -20 to +70 C. The grey body is standard; a D suffix swaps the release button to black.
No. AirTAC ships the 3/8in threaded stud with sealant pre-applied, so it seals against a clean PT port as installed. Only M5 sizes in this catalogue use a sealing gasket instead. Re-taping over the factory sealant is unnecessary and can push debris into the air line - wipe the port, thread it in, and wrench it snug.
