About the Airtac PCF Female Thread Straight Fitting PCF603D
The PCF603D is an AirTAC PCF female connector from the resin one-touch range. Its female PT thread is a 3/8 in tapped hole that screws straight onto a male stud or port, so you do not have to add a separate nipple before the fitting - the seal is made inside the fitting's own thread. The Dia 6 mm collet on the other end accepts exactly 6 mm outside diameter soft nylon or polyurethane tubing. The D suffix makes this the black-body version of the PCF; unlike on the PC and POC straight connectors, where D only changes the release button, on this series it recolours the whole body.
Connection is genuinely one-touch: push the 6 mm tube firmly into the collet and the internal stainless chuck springs grip it against pressure; press the POM release ring down and the tube slides straight back out. Working specification is the resin profile, not the metal line: 0 to 1.0 MPa (0 to 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 3/8 in thread arrives with sealant already applied, and internals include an aluminium-alloy guide, a brass stud and an NBR O-ring. The -750 mmHg vacuum rating means it is also valid on ejector and pick-and-place suction circuits, not just pressure lines.

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 PCF603D Is Used
Valve manifold outlets on packaging machines
The 3/8 in female thread screws directly onto the male outlet of a pneumatic valve manifold, eliminating a loose nipple, while the 6 mm tube runs out to a carton-clamp or label-head cylinder on a cartoning or wrapping line.
Vacuum suction circuits on electronics assembly cells
Rated to -750 mmHg, the fitting holds its grip on vacuum as well as pressure, making it suitable for feeding small suction cups that lift PCBs or display panels where a clean-looking black body is preferred inside the cell frame.
Filter-regulator take-offs on shop-air drop lines
Where a point-of-use filter-regulator presents a male 3/8 in port, this connector takes the 6 mm distribution tube straight off the regulator face, keeping the drop compact at the workstation.
Is the Airtac PCF Female Thread Straight Fitting PCF603D the Right Part?
Both directions of the tube ladder are open here: drop to Dia 4 if the line is a thin signal or pilot run where stiffness and space matter more than flow, or step up to Dia 8 when the same 3/8 in port feeds an actuator that breathes harder - the bore, not the fitting, sets how much air passes. On the thread side, a 1/4 in female body suits smaller manifold studs, while a 1/2 in version is the choice when the port has already been drilled for higher flow. Tube OD must match exactly: a Dia 6 collet will not seal or hold 1/4 in (6.35 mm) hose, even though the two look close.
Choose the PCF female shape when the machine already presents a male thread - a valve manifold stud, a cylinder port boss, a filter-regulator outlet - and you want the tubing angle to leave the axis of that port without adding a hex nipple in between. If you need the fitting to present a male thread instead, that is the PC series; if you need it to pass through a panel wall, look at the PMF bulkhead 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 PCF603D FAQ
It is a resin one-touch female connector joining Dia 6 mm tubing to a 3/8 in female PT thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the operating temperature range is -20 to +70 C. It is intended for soft nylon or polyurethane tubing, and the black body comes from the D colour suffix.
AirTAC ships threaded one-touch parts with sealant already applied to the thread, so in most cases extra tape is unnecessary. If you choose to add tape anyway, keep it off the last two threads so fragments cannot migrate into the air circuit. Note that M5 sizes in this range seal with a gasket instead of sealant, which does not apply to this 3/8 in model.
