Multi-line connectors
Twin-Tube
CPC Twin-Tube connects and disconnects two separate fluid or air lines in one motion. The coupling keeps both flow paths apart, has no valves and locks with the CPC thumb latch. Bodies mount low on the front panel of the equipment, while inserts carry hose barbs for 1/16" (1.6 mm) or 1/8" (3.2 mm) tubing. Ratings run from vacuum to 8.3 bar and, depending on the version, -40 to 71 °C or -40 to 82 °C, with POM (acetal) or ABS bodies and NBR, FKM or EPDM seals.

| Lines | 2 separate flow paths | For more lines, see Six-Tube and Ten-Tube. |
| Shutoff | non-valved | Fluid is not held back on disconnect, so depressurize the lines first. |
| Connection | hose barb 1/16" (1.6 mm) and 1/8" (3.2 mm) | Match the barb to the tubing inner diameter. |
| Mounting | panel mount body, in-line insert | Low profile on the equipment front. |
| Body | POM (acetal), ABS | ABS for parts that are gamma sterilized. |
| Seal | NBR, FKM, EPDM | Choose by fluid and cleaning agent. |
| Pressure | vacuum to 8.3 bar | Intended for low-pressure circuits inside equipment. |
| Temperature | -40 to 71 °C, -40 to 82 °C | The range depends on body and seal material. |
Frequently asked questions
- What is the Twin-Tube coupling used for?
- For equipment where two lines are disconnected together, such as supply and return or fluid and air. One coupling replaces two single connectors while the paths stay separate.
- Does Twin-Tube have a shutoff valve?
- No, Twin-Tube is non-valved. The lines do not close on disconnect, so they should be depressurized or drained first.
- Which tubing sizes fit?
- The inserts have hose barbs for 1/16" (1.6 mm) and 1/8" (3.2 mm) tubing inner diameter.
- Which version is meant for gamma sterilization?
- The versions with ABS bodies are intended for gamma sterilization, available as body and as insert with NBR or FKM seal.
- How is Twin-Tube mounted?
- The body snaps into the front panel of the equipment and sits almost flush. The insert stays on the tubing and locks in with the thumb latch.
