About the Airtac PCF Female Thread Straight Fitting PCF603
The PCF603 is an AirTAC PCF female connector from the resin one-touch range. It couples Dia 6 mm soft nylon or polyurethane tubing to a 3/8in PT internal thread, so it screws directly onto a male PT stud, port boss or gauge. To connect, push the tube straight into the chuck until it bottoms out - the stainless spring gasket and POM chuck grip it immediately. To release, press the POM release ring toward the body and the tube slides free. The 3/8in female thread leaves the factory with sealant already applied, so no tape or dope is needed on assembly.
This is the standard resin spec profile, not the metal BPC line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a service temperature of -20 to +70 C. The body is PBT with an aluminium-alloy guide and NBR O-ring, and the standard finish is grey - ordering the same code with a D suffix changes the body to black.

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 PCF Female Thread Straight Fitting PCF603 Is Used
Valve manifold take-off on a cartoning machine
The 3/8in female thread screws onto the male PT outlet of a solenoid manifold, feeding a Dia 6 mm line out to a small gripper or pusher cylinder on the carton-forming station.
CNC tool-clamp air feed
On a machining centre's air distribution block, the PCF603 converts a 3/8in tapped port into a push-in connection for 6 mm tubing running to the tool-clamp or chip-blow actuator.
Bench-top vacuum pick-and-place in an electronics lab
The -750 mmHg (10 Torr) vacuum rating lets the fitting sit on the suction side of a small ejector, with flexible 6 mm PU tube running to suction cups handling PCBs or glass slides.
Is the Airtac PCF Female Thread Straight Fitting PCF603 the Right Part?
A 3/8in PT port takes this fitting with Dia 6 mm tube, which is the smallest tube offered on a 3/8in port in the PC/PCF straight-connector ladder - there is nothing below it on that thread. The step up is PCF803 with Dia 8 mm: same port, wider bore, more capacity for a cylinder or ejector that needs it. If the port on your manifold is smaller, the same Dia 6 mm tube is available on a 1/4in female thread as PCF602, or on 1/8in as PCF601.
Two checks before ordering: the tube must match exactly, so a Dia 6 fitting will not hold 6.35 mm (1/4in) imperial hose; and if the line has to pass through a panel or machine wall rather than land on a port, the PMF bulkhead female connector in the same size is the shape you want instead.
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 PCF Female Thread Straight Fitting PCF603 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability -750 mmHg (10 Torr), operating temperature -20 to +70 C. The fitting joins Dia 6 mm soft nylon or polyurethane tube to a 3/8in PT female thread. These are the resin one-touch figures - the metal BPC family carries a lower 0.9 MPa rating.
No. AirTAC supplies threaded one-touch fittings with sealant already applied to the thread, so the PCF603 screws onto a male PT port as delivered. Only the M5 sizes in this catalogue use a sealing gasket instead. PT is a taper thread, so the sealant on the flanks does the sealing as it is tightened home.
