Standard couplings
APC
The APC series is a compact acetal (POM) quick disconnect with 1/4" flow and a plastic thumb latch. Few moving parts and a smooth, contoured shape make connecting straightforward. The couplings work from vacuum to 8.3 bar and from -40 to 82 °C, with NBR seals. Some versions add a latch shroud and a more rugged body.

How to choose APC
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | Specification | Note |
|---|---|---|
| Body | POM (acetal) | Lightweight, with plastic thumb latch. |
| Seal | NBR | |
| Temperature | -40 to 82 °C | |
| Pressure | vacuum to 8.3 bar | Also suitable for vacuum lines. |
| Thread | 1/4 and 3/8 NPT or BSPT male thread | BSPT is the tapered British pipe thread. |
| Tube connection | hose barb 6.4 mm (1/4") and 9.5 mm (3/8"), PTF compression 6.4 x 4.3 mm and 8 x 6 mm | Compression fittings suit plastic tubing with a fixed outside diameter. |

Frequently asked questions
- What pressure is the APC series rated for?
- APC couplings operate from vacuum to 8.3 bar at temperatures from -40 to 82 °C.
- Which terminations are available?
- NPT and BSPT male threads in 1/4 and 3/8, hose barbs for 6.4 mm and 9.5 mm hose, and PTF compression fittings for 6.4 x 4.3 mm and 8 x 6 mm tubing.
- What is the difference between in-line and panel mount?
- An in-line coupling floats freely in the hose line. A panel mount coupling is fixed through a wall or housing panel, keeping the connection point in one place.
- What is the shroud for?
- Versions with the suffix SH have a shroud around the thumb latch. The design is more rugged and, according to the manufacturer, widens the range of applications for the series.
