About the Airtac PLF L-Shaped Female Thread Adapter PLF4M5
The PLF4M5 is an AirTAC PLF female elbow from the resin one-touch fitting family. It connects Dia 4 mm soft nylon or polyurethane tubing to a female M5x0.8 threaded port, turning the airflow through 90 degrees at the connection. The M5 seat arrives with a sealing gasket pre-fitted, unlike the larger thread sizes in this catalogue which carry pre-applied sealant on the male thread.
Installation is the standard one-touch action: push the tube squarely into the chuck until it bottoms out, and the stainless spring gasket and NBR O-ring lock it against the aluminium-alloy guide; press the POM release ring to free it. This resin-profile fitting is rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The body is grey PBT with a brass stud, and the standard grey colour is the one buyers almost always need at this size.

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 PLF L-Shaped Female Thread Adapter PLF4M5 Is Used
Analytical instrument manifold
Labs and analytical instrument builders plumb purge and sample lines at Dia 4 mm, and the M5 female seat on the PLF4M5 screws straight onto the instrument's threaded port while the 90 degree turn keeps tubing clear of the housing.
Miniature pick-and-place gripper
A Dia 4 mm feed into a small parallel gripper on a pick-and-place head is exactly what this elbow was sized for: the M5 thread matches the compact valve port and the elbow points the hose along the arm instead of across it.
Micro cylinder inside a tight guard
On packaging and assembly machines, a micro cylinder port recessed behind guarding leaves no room for a straight fitting; the PLF4M5 threads into the female port and drops the Dia 4 mm tube down along the machine frame.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF4M5 the Right Part?
Dia 4 mm sits at the bottom of the PLF tube ladder, so there is no smaller tube to step down to; the next size up on the same M5 thread is Dia 6, which gains bore for shorter pressure drop on runs longer than roughly a metre. On the thread side, M5 is likewise the smallest port offered, so if your valve or manifold is drilled 1/8 in PT you need the 01-thread version of the same elbow instead of adapting down.
A female elbow is the right answer when the port is already threaded and recessed - for example on a compact valve body - and the tube must leave at right angles rather than straight out. Remember that the tube OD must match exactly: a Dia 4 mm chuck will not grip 5/32 in (4.76 mm) tube, even though the two look interchangeable on a ruler.
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 PLF L-Shaped Female Thread Adapter PLF4M5 FAQ
It is a Dia 4 mm tube by M5x0.8 female thread elbow from the resin one-touch range. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum rating is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tubing only.
No. On M5 sizes AirTAC fits a sealing gasket rather than using thread sealant, so the PLF4M5 seals on the gasket face when screwed into the port. Adding tape over the gasket seat can actually prevent it from seating properly - keep the M5 face clean and hand-snug the fitting instead.
