About the Airtac PCF Female Thread Straight Fitting PCF1203
The PCF1203 is an AirTAC PCF female connector, the threaded one-touch fitting that joins a Dia 12 mm tube to a 3/8in female PT port. Because the port side is female, you mate it with a male PT nipple, stud or plug rather than threading it straight onto a male boss - handy wherever a machine builder has already fitted male studs to a manifold or housing. Push the tube firmly into the chuck and it grips for pressure-tight service; press the POM release ring against the body and the tube slides back out.
This is a resin-line fitting, not a metal one: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The body is PBT with a brass stud, the chuck and button are POM, and the seal is an NBR O-ring over a stainless spring gasket. AirTAC ships threaded sizes with sealant already on the thread, so the 3/8in female port seals on installation without extra tape. Use soft nylon or polyurethane tube with an exact 12 mm outside diameter.

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 PCF1203 Is Used
Valve manifold outlet on a cartoning machine
The manifold ports carry male PT studs, so the PCF1203 threads onto them directly and hands off to a 12 mm nylon trunk line feeding the downstream actuators - no adaptor stack in between.
Pneumatic press supply past a fixed guard
A straight female connector lets the 12 mm polyurethane drop line route in-line through the guard framework to the press cylinder's male-studded inlet, with the push-fit joint made in open air where it can be inspected.
Compressor room distribution take-off
On a compressor aftercooler or receiver with 3/8in female ports already piped, the PCF1203 picks up a 12 mm soft nylon feed to a workbench FRL set without touching threaded pipework again.
Is the Airtac PCF Female Thread Straight Fitting PCF1203 the Right Part?
On the 3/8in thread, Dia 12 is the largest tube the size ladder offers - step down one place and PCF-style fittings in Dia 10 give you the same port with a narrower bore, trading capacity for a slimmer tube run and smaller bend radius. If the tube stays at 12 mm but the port is bigger, move to the 1/2in threaded version instead, which also accepts Dia 12; the thread choice is set by the port, the tube choice by the flow path. Whichever way you go, the tube OD must match the fitting exactly: a Dia 12 chuck will not seal on 1/2in (12.7 mm) imperial hose.
A female connector earns its place when the port hardware is already male-studded - valve manifolds, threaded bosses on machine frames, or pipe nipples off a supply line. If you need to turn the run 90 degrees at the port, the PLF female elbow is the shape to look at instead; if the fitting must pass through a panel wall, that is bulkhead territory, not this straight connector.
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 PCF1203 FAQ
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. It connects Dia 12 mm soft nylon or polyurethane tube to a 3/8in female PT thread. The body is PBT with a brass stud; the release button and chuck are POM and the seal is an NBR O-ring with a stainless spring gasket.
No. AirTAC applies sealant to the thread of every threaded one-touch fitting before packing, so the PCF1203 is ready to wind onto a male PT nipple as delivered. Thread it hand-tight plus a firm turn onto a clean male PT stud - never onto NPT or BSPP hardware, which has a different thread form and will not seal. Keep the mating male thread clean and burr-free so the sealant bed is not scraped off.
