About the Airtac PLL L-Type Extended Thread Connector PLL803
The PLL803 is an AirTAC PLL extended male elbow, a one-touch fitting that turns a Dia 8 mm tube through 90 degrees onto a 3/8 inch male thread. The extension between the elbow body and the thread is the whole point of the PLL prefix: the longer stud lifts the connection clear of guards, manifolds and port bosses that a standard PL elbow would foul.
To make the joint, push the 8 mm tube straight in until it bottoms - the POM chuck inside grips the OD while the stainless spring gasket seats - and it is sealed under working pressure. Press the release ring in and the tube slides free. This is the resin / brass spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C, on soft nylon or PU tubing. The 3/8in thread ships with sealant applied and uses PT taper form, so no extra tape is needed on the male thread.

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 PLL803 Is Used
Valve manifold exhaust line
On a 5/2 solenoid manifold where the exhaust port faces the mounting rail, the PLL803 turns the Dia 8 muffler line through 90 degrees and the extended stud clears the rail edge, keeping the silencer path open.
Cylinder port behind a machine guard
An ISO 15552 cylinder on a packaging machine with a recessed 3/8in port takes the PLL803 directly; the Dia 8 supply line drops vertically without kinking against the tie-rod.
Fume-extraction cabinet plumbing
In a lab extraction cabinet, the extended stand-off keeps the Dia 8 PU line away from a warm rear panel, inside the -20 to +70 C window of this resin profile.
Is the Airtac PLL L-Type Extended Thread Connector PLL803 the Right Part?
On the 3/8in PLL ladder, the neighbours are PLL603 one size down and PLL1003 one size up. Dropping to Dia 6 buys compactness for light pick-and-place circuits; stepping to Dia 10 roughly doubles the bore area and is the move when a longer cylinder stroke or faster exhaust matters. All three share the same 3/8in port, so you can resize tubing without re-tapping the manifold.
The 90 degree turn matters where a straight connector cannot be inserted - a shallow NEMA-style valve recess, a port facing a machine wall. Choose PL instead of PLL only when the port face is truly unobstructed; if anything projects within about 10 mm of it, the extended stud is the safer answer. The tube side must be exactly Dia 8: a 1/4 inch nominal hose at 6.35 mm will not grip, and an 8 mm tube will not enter a Dia 6 or Dia 10 pocket. Never side-load the elbow during tightening - hold the hex flats, not the body.
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 PLL803 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It connects Dia 8 mm soft nylon or polyurethane tube to a 3/8 inch PT male thread. The body is PBT with a brass stud, the release button and chuck are POM, and the O-ring is NBR. Thread sealant is factory-applied on the 3/8in stud.
Both are 90 degree elbows for Dia 8 tube on a 3/8in thread with the same ratings. The PLL adds an extended male stud between the elbow and the thread. That stand-off matters wherever the fitting must clear a guard panel, a port boss or an adjacent elbow on a manifold. If your port face is clear, PL803 is the shorter option; if anything sits close to it, the extended body prevents side-loading of the tube at the chuck.
