Standard couplings
MC
MC is the metal member of the CPC 1/8" coupling family: chrome-plated brass bodies, NBR seals and a rating from vacuum to 17.3 bar at -40 to 82 °C. Choose it for lines where pressure or temperature is too high for a plastic coupling. The thumb latch allows one-hand connection and release, and MC parts mate with the PMC and PMC12 plastic series.

How to choose MC
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | Available | Note |
|---|---|---|
| Body material | Chrome-plated brass | Tougher than plastic, suited to higher pressure and temperature. |
| Seal | NBR | Works with water, air and oils in general machinery. |
| Pressure | Vacuum to 17.3 bar | Roughly twice the 8.3 bar of the PMC and PMC12 plastic series. |
| Temperature | -40 to 82 °C | Wide range, including chilled media. |
| Body type | In-line coupling, panel mount coupling, insert | Panel mount bodies fit through a housing wall or sheet metal. |
| Termination | NPT and BSPT male thread, hose barb 3.2 to 6.4 mm, PTF compression fitting | BSPT for Whitworth threads, NPT for American pipe threads. |
Frequently asked questions
- When should I use MC instead of a plastic coupling?
- Whenever the line runs above 8.3 bar, sees higher temperatures or the coupling takes mechanical abuse. MC is rated to 17.3 bar and from -40 to 82 °C.
- Does MC mate with PMC and PMC12?
- Yes. MC couplings are intermateable with acetal PMC and polypropylene PMC12 parts, so a brass body can be paired with a plastic insert, for example.
- Do MC couplings shut off when disconnected?
- The MC parts listed here are non-valved. After disconnection the line is open and fluid can escape.
- Which terminations are available?
- NPT and BSPT male threads, hose barbs from 3.2 mm (1/8") to 6.4 mm (1/4") and PTF compression fittings for 4.0 x 2.5 mm and 6.4 x 4.3 mm tubing.
