CPC medical couplings join tubing in bag systems, lab setups and medical fluid lines by hand, without tools. The group covers the MPC and MPX series, which push together and release with a thumb latch, and the SMC polycarbonate series, a twist-to-connect alternative to luer fittings. Housings are mostly polycarbonate, with ABS and PVC as further options, and seals are silicone or NBR. Depending on the series the rating is 4.1 bar or 6.9 bar, and the temperature range is -40 to 121 °C, or -40 to 71 °C on some versions.

How to choose Medical couplings
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | Available | Note |
|---|---|---|
| Series | MPC, MPX, SMC polycarbonate | MPC and MPX push together, SMC twists. |
| Tubing size | 1/16" to 3/4" hose barb | SMC for 1/16" and 1/8", MPC up to 3/8", MPX up to 3/4". |
| Housing material | Polycarbonate, ABS, PVC | USP Class VI polycarbonate for sterilisable applications. |
| Seal | Silicone, NBR | Match it to the medium and the sterilisation method. |
| Maximum pressure | 4.1 bar (MPC, MPX), 6.9 bar (SMC) | All series are also rated for vacuum. |
| Temperature | -40 to 121 °C, -40 to 71 °C | Up to 121 °C for autoclaving. |
| Retention | Locking sleeve, twist lock | Prevents separation during a transfer. |
Frequently asked questions
- How do MPC and MPX differ?
- MPC fits 1/8", 1/4" and 3/8" tubing and suits smaller bag systems in particular. MPX covers 3/8", 1/2" and 3/4". A back-to-back adapter joins an MPX line to an MPC connection.
- When should I choose the SMC polycarbonate series?
- For very small tubing of 1/16" or 1/8", and wherever luer connections are used today. SMC connects with a twist, holds up to 6.9 bar and lets the tubing rotate freely while coupled.
- Can the couplings be sterilised?
- The polycarbonate versions to USP Class VI are designed for autoclaving up to 121 °C, while selected ABS parts are intended for gamma sterilisation. The product description of each part states which method it tolerates.
- How do I prevent accidental disconnection?
- MPC and MPX accept optional locking sleeves that hold the coupled halves together. On SMC, the twist connection itself keeps the joint closed.
- How do I protect lines that are disconnected?
- Caps and plugs for MPC and MPX seal open coupling halves before and between transfers.
