About the Airtac PLL L-Type Extended Thread Connector PLL1203-S
The PLL1203-S is an AirTAC PLL extended male elbow from the resin one-touch range, joining a Dia 12 mm soft nylon or polyurethane tube to a 3/8 in PT male port. The extended neck is the whole point of this prefix: the elbow stands the tube off from the mounting face, so a spanner has clearance on the port and the tube turns 90 degrees without kinking against the machine wall. On the -S variant the body stays PBT while the male stud is SUS304 stainless, so the thread into the port resists corrosion even where the fitting body itself is plastic.
Installation is the standard one-touch action. Push the 12 mm tube into the chuck until it bottoms and the stainless spring gasket and POM chuck grip it against the guide; press the release ring to free it. This is the resin spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and -20 to +70 C. The male thread arrives pre-coated with sealant, so it seals on the PT taper without extra tape. Take the tube, not the fitting, as the temperature limit if your line runs warm.

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 PLL1203-S Is Used
Coolant-side valve manifolds
The SUS304 stud threads into a 3/8 in machined manifold port on a wash-down coolant or chilled-water skid, and the PBT body keeps the elbow clear of adjacent valve bodies so the 12 mm tube drops vertically to the actuator.
Plating line rinse stations
On electroplating rinse tanks where mist and acid fumes attack brass threads, the stainless stud of the PLL1203-S seats into the 3/8 in nozzle port while the 12 mm PU feed line plugs in without tools.
Bottling line air ring actuators
A pneumatic reject-actuator on a PET bottling conveyor sits with its port facing the frame, so the extended 3/8 in male elbow keeps wrench clearance and turns the 12 mm air line 90 degrees toward the valve bank.
Is the Airtac PLL L-Type Extended Thread Connector PLL1203-S the Right Part?
On the 3/8 in thread, Dia 12 is the top of the PL ladder, so the only neighbour on this port is PLL1003-S at Dia 10; stepping down lightens the line and the flow demand the bore can carry, while nothing larger exists on a 3/8 in PL - a 1/2 in PLL is only made in Dia 10 and Dia 12, so PLL1204-S is the step up if the port allows it. Note the extended neck is roughly a release-button width longer than a standard PL1203, which is exactly what buys spanner access inside a guard. Tube OD must match exactly: a Dia 12 chuck will not seal on 1/2 in imperial hose, and no adapter exists for that mismatch in this range.
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 PLL1203-S FAQ
Extended male elbow one-touch fitting, Dia 12 mm tube by 3/8 in PT male thread, with SUS304 stud and PBT body. Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), temperature -20 to +70 C. Rated for soft nylon or polyurethane tubing only. Flow is published by AirTAC as a characteristic curve, not a single figure - use the 12 mm bore as the capacity guide.
On elbow, tee and Y prefixes (PL, PLL, PEB, PED, PYB, PZB, PH, PHF, PHW), AirTAC makes the -S upgrade as a SUS304 male stud rather than a solid stainless body; only the straight PC and POC connectors get a full 304 body. The ratings are identical to the grey standard part - same 1.0 MPa, same 1.5 MPa proof, same -20 to +70 C - and the dimensions match the standard catalogue exactly, so it is a like-for-like swap.
