About the Airtac PLF L-Shaped Female Thread Adapter PLF4M5D
The PLF4M5D is AirTAC's PLF female elbow from the resin one-touch range, turning a Dia 4 mm soft nylon or polyurethane tube through 90 degrees into a female M5x0.8 port. Push the tube fully home and the internal chuck grips it; press the POM release ring and the same chuck lets go. Unlike the larger thread codes, which arrive with sealant pre-applied to the stud, the M5 port on this fitting is sealed by a dedicated gasket - no PTFE tape and no thread compound belong on it.
This is the standard resin/brass spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The body is PBT with a brass stud and an NBR O-ring at the grip. The trailing D marks the black version - on the PLF family that means the body itself is black, not just the release button as on the PC and POC straights.

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 PLF4M5D Is Used
Compact diagnostics analyser
Pilot air feed to an M5-port solenoid manifold inside a benchtop in-vitro instrument, where the 90-degree female entry keeps the Dia 4 nylon line flat against the chassis instead of looping over the valve block.
Delta robot pick-and-place gripper
Direct connection from a Dia 4 polyurethane drop line to the M5 male stud on a compact pneumatic gripper, with the elbow absorbing the swing angle at the end of the arm.
Electronics fixture control panel
Black-body elbow hooking Dia 4 tube to M5 ports on a fixture's valve island, where the dark PBT housing matches black anodised panels and the right-angle entry clears the wiring duct above it.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF4M5D the Right Part?
Dia 4 mm is the smallest tube the M5 ladder carries, so there is no size below it. The only step up on this thread is Dia 6 (PLF6M5D territory), which buys you a wider bore for circuits where qualitative flow capacity matters more than absolute compactness. If your port is 1/8 inch instead of M5, the same Dia 4 elbow exists with a male stud as PL4M5, and the threaded PL male elbow PL401 covers 1/8 inch directly.
Use a female elbow when the mating part already has a male stud or a male-threaded valve port, so the fitting's female gasket face meets it without a second adaptor. For mounting through a panel wall, the PMF bulkhead connector (PMF401 in Dia 4 with a 1/8 inch thread) is the shape you want instead. One hard rule: the tube OD must match the fitting exactly - a Dia 4 chuck will not seal on 5 mm or 1/4 inch tube.
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 PLF4M5D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and an operating temperature range of -20 to +70 C. This unit joins Dia 4 mm soft nylon or polyurethane tube to a female M5x0.8 thread, with PT as the thread standard across this catalogue.
No. M5 sizes in this range are sealed by a gasket seat rather than by sealant on the threads, so adding PTFE tape can actually distort the joint or block the tiny M5x0.8 orifice. The larger thread codes (1/8 inch and up) are the ones that arrive with sealant pre-applied to the male stud.
