CPC
Multi-line connectors
CPC multi-line connectors join and separate several fluid or air lines in one movement. The range covers the dual-port DPC and DTLD series, Twin-Tube, Six-Tube and Ten-Tube for two, six or ten lines, and Multi-Mount, which groups three to five couplings on one plate. Bodies are made of acetal (POM), polypropylene, ABS or chrome-plated and nickel-plated brass, and most seals are NBR. Depending on the series, the working pressure runs from vacuum up to between 1.38 and 8.3 bar, and temperatures range from -40 °C to 82 °C.

Buying guide
How to choose Multi-line connectors
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | What matters | In the range |
|---|---|---|
| Number of lines | This chooses the series. The more lines one coupling carries, the fewer movements a changeover takes, though the bore per line is usually smaller. | DPC, DTLD and Twin-Tube for two, Multi-Mount for three to five, Six-Tube for six, Ten-Tube for ten lines |
| Shut-off | With shut-off valves both halves stay closed when disconnected; non-valved versions give more flow and a simpler design. | DPC, Multi-Mount, Six-Tube and Ten-Tube with or without valves, DTLD valved, Twin-Tube non-valved |
| Pressure | The permitted pressure depends on series and material; for Multi-Tube it applies per line. | Vacuum to 1.38 bar (DTLD), 6.9 bar (Six-Tube, Ten-Tube), 8.3 bar (DPC, Multi-Mount) |
| Temperature | Fluid and surroundings must stay within the series range; the seal is usually the limiting factor. | -40 to 82 °C, 0 to 82 °C or 0 to 48 °C depending on the series |
| Connection | Hose barbs suit flexible tubing, female threads suit rigid lines and fittings. | Hose barbs from 1/16" (1.6 mm) to 3/8" (9.5 mm), metric 3 mm, female thread on Multi-Mount |
| Mounting | Panel mounting holds one half firmly in the equipment, in-line versions hang free in the line. | Panel mount, snap-in panel mount (Six-Tube), in-line, aluminium mounting plates |
Frequently asked questions
- When is a multi-line connector better than individual couplings?
- When several lines are always separated together, for example when swapping a module or consumer. One movement replaces several, and lines cannot be mixed up because each one sits in a fixed position in the housing.
- How do Six-Tube and Ten-Tube differ?
- Six-Tube carries up to six lines, locks with the CPC thumb latch and snaps flush into the front panel, with valves on the insert side. Ten-Tube takes up to ten lines, locks with a slide latch and has its valves on the body side, for panel or in-line mounting.
- How does Multi-Mount prevent mismatched connections?
- Multi-Mount couplings are keyed so that only matching halves fit together. Three to five couplings share one plate and connect in a single action.
- What pressure do the multi-line connectors handle?
- It depends on the series: DTLD is rated to 1.38 bar, Six-Tube and Ten-Tube to 6.9 bar per line, DPC and Multi-Mount to 8.3 bar. All series are also suitable for vacuum.
- Are valved versions available?
- Yes. DPC, Multi-Mount, Six-Tube and Ten-Tube come with or without shut-off valves, and DTLD is always valved. Twin-Tube keeps two separate flow paths without valves.
