About the Airtac PL L Connector PL4M5D-S
The PL4M5D-S is an AirTAC PL male elbow in the one-touch resin range, joining Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 male thread at a right angle. Push the tube straight into the chuck until it bottoms out and the stainless spring gasket and POM chuck grip it for pressure on both lines; press the release ring to free it. The 90 degree body turns the tube run without kinking it in the small space an M5 port normally sits in.
This -S variant carries a SUS304 stainless stud on the elbow, while the body itself stays glass-reinforced PBT in black (the D suffix), so it suits corrosive or wash-prone spots without the cost of a full stainless body. Ratings follow the standard resin profile: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure, -20 to +70 C. Unlike the larger PT threads, the M5 stud seals with its seating gasket, so no thread sealant is applied and none is needed.

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 PL4M5D-S Is Used
Analytical instrument sampling line
On a gas analyser or lab sampling manifold, M5 ports are the standard small tap. The SUS304 stud shrugs off the reagent splashes and humidity that pit a plain brass stud, and the 4 mm bore keeps dead volume low on short sample draws.
Compact pick-and-place gripper feed
A small parallel gripper on a desktop gantry usually takes its air through an M5 port facing sideways. This elbow feeds it from above, so the 4 mm PU tube drops vertically and clears the gripper jaws through their full stroke.
Valve manifold pilot supply
Iso-valve manifolds often expose a spare M5 pilot port on the end plate. Screwing this elbow in and running 4 mm tube to a pressure switch or pilot regulator adds a monitoring leg without replumbing the manifold.
Is the Airtac PL L Connector PL4M5D-S the Right Part?
Dia 4 is the smallest tube the PL M5 ladder offers, so there is no size below it; the only step up is the Dia 6 bore (PL6M5-S), which moves noticeably more air through the same M5 port but needs the extra room for its larger elbow body. On the thread side, M5 is the bottom of the ladder: the next port up is 1/8 PT (PL401-S), also available in Dia 4 if your manifold has tapped holes rather than M5 inserts. Match the port exactly, because a Dia 4 one-touch chuck will not seal on 5/32 in or any other near-miss tube.
If the tube has to pass through a panel wall instead of ending at it, the bulkhead male elbow PLM is the shape to look at; if the drop needs to swivel to line up with the actuator, the PH universal elbow covers that case.
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 PL4M5D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting accepts Dia 4 mm soft nylon or polyurethane tube and carries an M5x0.8 male thread; the family thread standard is PT. These figures are the resin one-touch profile and the -S stainless stud does not change any of them.
No. On the PL family the -S suffix makes the male stud SUS304; the elbow body remains PBT, here in black. Only the PC and POC straight connectors get a solid SUS304 body in AirTAC's stainless line. The practical benefit on this part is a corrosion-resistant, copper-free threaded stud where it meets a wet or aggressive port, while the PBT body keeps the elbow light and compact.
