About the Airtac PLL L-Type Extended Thread Connector PLL802D-S
The PLL802D-S is an AirTAC PLL extended male elbow from the resin one-touch range, joining a Dia 8 mm soft nylon or polyurethane tube to a 1/4 in PT male thread. Extended is the operative word: the threaded stud on a PLL is longer than the stud on the standard PL elbow, so a spanner has more engagement room and the elbow body clears neighbouring ports on crowded manifolds. Connection is genuinely one-touch - push the tube squarely home until it seats, the stainless spring gasket and chuck clamp it, and pressing the release ring frees it again.
This is the -S stainless variant, and its material split matters: the elbow body stays PBT while the male stud is SUS304, so the corrosion-prone thread side - the part that sees moisture, washdown and atmospheric attack - is the stainless side. It arrives in black (the D suffix changes the body colour on this series, not just the button) with sealant already applied to the thread, so it seals on assembly without extra tape or paste. Ratings are the standard resin profile: 0 to 1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C.

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 PLL802D-S Is Used
Washdown manifold on a food bottle rinser
On a rinser or filler frame hosed down each shift, the SUS304 stud resists the wet, detergent-laden air side of the circuit, while the long PLL stud gives the fitter spanner room between closely pitched manifold ports.
Valve island outlet in a tight guard
The extended elbow turns 90 degrees and reaches clear of a compact valve body, so 8 mm tube to a gripper or clamp cylinder can be routed along the guard wall without fouling adjacent solenoid outlets.
Plating line actuator drops
Over electroplating tanks and pickling cells, airborne acid attacks brass hardware; a stainless stud on the air feed to a lift or transfer cylinder keeps the threaded connection serviceable where a plain brass PL would corrode.
Is the Airtac PLL L-Type Extended Thread Connector PLL802D-S the Right Part?
Size both axes before ordering. On the tube side, Dia 8 sits between PLL602 (Dia 6 to the same 1/4 in thread) and PLL1002 (Dia 10) - step down when the line feeds a compact actuator or sensor port, step up when flow over a long run to a cylinder matters; the bore is what carries the air, so the fitting itself adds no restriction beyond the tube. On the thread side, Dia 8 is also offered as PLL801 (1/8 in) and PLL803 (3/8 in); match the thread to the port, not the tube, and remember the sealant-coated PT thread needs no additional sealing compound.
Two traps to avoid. First, tube OD must match exactly - a Dia 8 chuck will not grip 5/16 in or 10 mm tube. Second, if you are scanning the ladder for a 1/2 in PLL, that size only exists in Dia 10 and Dia 12, so a 1/2 in port with 8 mm tube means stepping the port with a reducer rather than this part.
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 PLL802D-S FAQ
It is an AirTAC PLL extended male elbow for Dia 8 mm soft nylon or polyurethane tube with a 1/4 in PT male thread, black body, SUS304 stud and PBT elbow body. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr) and operating temperature -20 to +70 C. The thread arrives factory-sealed and the rating is identical to the non-stainless PLL802D - the -S changes materials on the stud, not performance.
The PLL's longer stud gives deeper thread engagement, so there is room for a spanner where ports sit close together and the elbow body stands off from the manifold face - useful in tight guards and on crowded valve islands. On the colour code, D on the PLL series changes the whole elbow body to black, not merely the release button as on the PC and POC straight connectors; performance is unaffected.
