Food and beverage couplings (NSF)
MC-NSF
MC NSF are small chrome-plated brass quick disconnects built for higher temperatures and pressures, connected and released with one hand. They mate with PMC acetal and PMC12 polypropylene couplings and are listed under the criteria of the NSF/ANSI standards. The rated range is -40 to 82 °C with NBR (Buna-N) seals. Terminations include 1/8" and 1/4" NPT threads, 3.2 mm (1/8") or 6.4 mm (1/4") hose barbs and a PTF compression fitting; one elbow insert is made of acetal.

Buying guide
How to choose MC-NSF
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | In this category | Note |
|---|---|---|
| Body | Chrome-plated brass, acetal (POM) | Brass for heavier duty. |
| Seal | NBR (Buna-N) | For water and beverage lines. |
| Temperature | -40 to 82 °C | Same range as acetal PMC. |
| Compatibility | PMC, PMC12 | Metal and plastic halves can be combined. |
| Valve | valved and non-valved | Non-valved parts have a straight-through path. |
| Termination | NPT 1/8" and 1/4", hose barb 3.2 mm (1/8") and 6.4 mm (1/4"), PTF 1/4" | In-line, elbow or panel mount. |
Frequently asked questions
- Which couplings does MC mate with?
- MC mates with acetal PMC and polypropylene PMC12, so a rugged brass half can be paired with a light plastic half.
- When to choose MC instead of PMC?
- When higher temperature or pressure occurs or the coupling sees more mechanical stress. Acetal PMC is lighter and intended for general dispensing.
- Which terminations are available?
- 1/8" and 1/4" NPT male threads, hose barbs for 3.2 mm (1/8") and 6.4 mm (1/4") and a PTF compression fitting for 1/4" tubing. Mounting is free floating, panel mount or threaded.
