Standard couplings
PLC
PLC is the CPC 1/4" coupling series in acetal (POM) with NBR seals, and the range with the broadest choice of sizes and terminations. The couplings are rated to 8.3 bar from -40 to 82 °C and resist most mild chemical solutions. Integral terminations remove adapters and the leak points that come with them, and the parts mate with LC metal and PLC12 polypropylene couplings.

How to choose PLC
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | Available | Note |
|---|---|---|
| Body material | POM (acetal) | Dimensionally stable and resistant to most mild chemicals. |
| Seal | NBR | For water, air and oils. |
| Pressure | up to 8.3 bar | For more pressure, move to the LC metal series. |
| Temperature | -40 to 82 °C | Also suitable for chilled media. |
| Termination size | 1/4", 5/16", 3/8", 8 mm, 10 mm | Match it to the tubing ID or thread. |
| Termination type | NPT and BSPT thread, hose barb, John Guest push-in, PTF | The push-in fitting accepts plastic tubing without tools. |
Frequently asked questions
- What is PLC used for?
- General-purpose liquid and air lines with 1/4" flow, for example in instruments, machines and lab setups where lines are disconnected regularly.
- Which series does PLC mate with?
- PLC is intermateable with LC metal and PLC12 polypropylene couplings, so metal and plastic can be mixed depending on where the coupling sits.
- What pressure do PLC couplings handle?
- The series is rated to 8.3 bar at temperatures from -40 to 82 °C.
- Why integral terminations?
- Thread, hose barb or push-in fitting is molded into the coupling body. That means fewer leak points, shorter assemblies and faster installation.
