About the Airtac PLL L-Type Extended Thread Connector PLL1004D-S
The PLL1004D-S is an AirTAC PLL extended male elbow from the resin and brass one-touch range, joining a Dia 10 mm tube to a 1/2in PT male thread at a right angle. The extended neck carries the thread further out from the elbow body than a standard PL, so the fitting clears port bosses, guards and panel flanges before turning. To connect, push the tube straight in until it bottoms: the POM chuck inside grips it for a sealed joint, and pressing the release ring frees it again. This is the resin-line pressure profile, not the metal BPC line: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C.
The -S suffix does not make the whole fitting stainless. On the PLL family the body remains PBT - here in the D black colour, which on this series changes the body rather than just the button - and it is the male stud that is SUS304. That puts the corrosion-resistant material exactly where the fitting meets the machine port, which matters in damp or wash-down areas where threads rust first. AirTAC ships threaded parts with sealant already on the thread, so the 1/2in PT end seals without extra tape in most cases.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PLL L-Type Extended Thread Connector PLL1004D-S Is Used
Palletiser grip circuit off a 1/2in manifold
Vacuum-ejector and gripper lines on a palletiser often start at a 1/2in valve manifold port. This elbow steps straight to Dia 10 tubing at the port and the SUS304 stud resists rust in dusty, sometimes humid warehouse air.
Cylinder port inside a tight machine guard
On a packaging machine where the cylinder port sits close to the guard frame, the extended neck clears the boss before the elbow turns, letting Dia 10 tube route vertically instead of kinking sideways.
Rinse-zone air supply on a bottling line
Conveyor tracking cylinders near the rinse section see wet threads corrode first. The SUS304 stud and black PBT body hold up at the port interface, with the standard resin-line rating unchanged.
Is the Airtac PLL L-Type Extended Thread Connector PLL1004D-S the Right Part?
On a 1/2in PT thread the PLL ladder only exists in Dia 10 and Dia 12, so this is the smallest tube AirTAC makes on that thread - there is no PLL 1/2in version below Dia 10, and any supplier offering one is not reading the same catalogue. Step up to the Dia 12 version if you are feeding larger-bore cylinders or longer runs where pressure drop matters; the bore gain is real but modest, so pick by the tubing you already run. If Dia 10 tube is fixed but the port is 3/8in, PLL1003-S is the correct sibling and it widens the tube ladder to 6, 8, 10 and 12.
Match the 1/2in PT stud to a genuinely 1/2in port - adapter bosses and reducing bushings add joints and leak points. And remember tube OD must match exactly: a Dia 10 one-touch chuck will not seal on 3/8in (10 mm nominal Imperial) tube reliably, because the tolerances differ.
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 PLL L-Type Extended Thread Connector PLL1004D-S FAQ
It is an extended male elbow for Dia 10 mm tube with a 1/2in PT male 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. The body is PBT in black (D colour), the male stud is SUS304, and the internal chuck and release button are POM with an NBR O-ring. Applicable tubing is soft nylon or polyurethane.
No. On the PLL family the -S makes the male stud SUS304 while the elbow body stays PBT - in this case the black D-colour version. Pressure, vacuum and temperature ratings are identical to the standard PLL1004D. If you need an all-stainless body on a straight connector rather than an elbow, that exists only in the PC and POC families, not PLL.
