About the Airtac PL L Connector PL1203-S
The PL1203-S is an AirTAC PL series one-touch male elbow: a 90-degree threaded connector that takes Dia 12 mm soft nylon or polyurethane tubing into a 3/8in PT male thread. Push the tube into the chuck and the stainless spring gasket and NBR O-ring seal it instantly; press the POM release ring and the tube slides straight back out. The elbow body turns on the thread, so the tube can approach the port from whatever angle the machine leaves you.
This is the resin and brass fitting line, rated 0-1.0 MPa working pressure (0-10 kgf/cm2), 1.5 MPa proof, and -20 to +70 C, with -750 mmHg (10 Torr) vacuum capability. The -S suffix fits a SUS304 stud in place of the standard brass one while the body remains PBT, so the corrosion-resistant metal sits exactly where the fitting meets the machine port. The 3/8in thread arrives with sealant already applied - only M5 sizes in this catalogue use a sealing gasket instead - so it is ready to wind in and torque down.

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 PL L Connector PL1203-S Is Used
Clamp cylinder feed on a stamping press
A 12 mm drop line to a heavy pneumatic clamp on a press line benefits from the large bore, and the elbow lets the tube enter the cylinder port vertically even when the guard rail sits close.
Wash-down food conveyor actuator
On a bakery or meat-processing conveyor the port threads sit in a damp zone all shift; the SUS304 stud resists corrosion at that joint while the PBT body keeps the fitting light.
Fume-scrubber pilot skid
A pilot chemical skid with 3/8in PT ports on valve manifolds takes the elbow at an angle that keeps polyurethane tubing clear of hot pipework and away from drip paths.
Is the Airtac PL L Connector PL1203-S the Right Part?
On the PL 3/8in ladder, Dia 12 is the top rung. The only neighbour below is Dia 10 (PL1003-S); stepping down reduces the bore and the air volume the fitting passes, and the 12 mm version is the one to pick when a long run or a high-consumption actuator sits downstream. PL also exists with a 1/2in thread in Dia 12 if the port on the machine is larger. Match the thread to the port, not to habit - a 3/8in thread in a 1/4in tapped hole will not seal, sealant or not.
Tube OD must match exactly: a Dia 12 chuck will not grip 1/2in (12.7 mm) imperial tube, and no adaptor inside this catalogue changes that. If the line needs to pass through a panel, PM or PLM bulkhead shapes are the right answer instead of an elbow; if it needs to shrink to a smaller actuator line, a PG or PKG reducer is the correct 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 PL L Connector PL1203-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2); proof pressure 1.5 MPa; temperature range -20 to +70 C; vacuum capability -750 mmHg (10 Torr); tubing Dia 12 mm soft nylon or polyurethane; thread 3/8in PT male. It belongs to the resin and brass one-touch line, and the -S suffix adds a SUS304 stud without changing any of these figures.
No. On PL, PLL, PEB, PED, PYB, PZB, PH, PHF and PHW stainless variants, only the stud is SUS304 - the elbow body itself stays PBT, with a POM release ring, aluminium-alloy guide, stainless spring gasket and NBR O-ring. If you need an all-stainless body, the -S versions of the PC and POC straight connectors are the parts where the body itself is SUS304. Pressure, temperature and dimensional figures are identical between standard and -S parts.
