Description
Prevost CSM Metal Safety Quick Male Coupler - ISO 6150 C Profile
Prevost CSM Metal Safety Quick Male Couplers provide a rugged, safety-focused compressed-air connection for professional pneumatic systems using the ISO 6150 C profile. This listing combines 1/4", 3/8", and 1/2" ID Passage sizes with multiple male NPT connections, allowing the required airflow capacity and threaded connection size to be selected independently.
The CSM safety system uses an anti-whiplash two-stage disconnection process. During release, the coupling first automatically decompresses the downstream hose and then safely disconnects the plug. The stainless-steel construction is engineered to resist abrasion, shock, crushing, vibration, and corrosion for dependable service in demanding compressed-air applications.

Understanding ID Passage vs. Male NPT Size
The ID Passage size and male NPT connection size describe two different parts of the coupler and do not need to be the same nominal size.
The ID Passage determines the internal airflow path and quick-connect coupling family. The male NPT size determines how the coupler connects to a female-threaded compressed-air fitting, manifold, regulator, piping outlet, hose fitting, or other pneumatic component.
- CSM 06: Nominal 1/4" ID Passage
- CSM 08: Nominal 3/8" ID Passage
- CSM 11: Nominal 1/2" ID Passage
- Male NPT size does not determine quick-connect plug compatibility.
- Always verify both the ID Passage/profile family and male thread size before ordering.
Male NPT Connection Options
1/4" Male NPT
Available with the 1/4" and 3/8" ID Passage families for systems using a 1/4" female NPT connection.
3/8" Male NPT
Available across the 1/4", 3/8", and 1/2" ID Passage families.
1/2" & 3/4" Male NPT
1/2" male NPT is available across all three ID Passage families. The 1/2" ID Passage family also includes a 3/4" male NPT configuration.
Sealing & Pneumatic Efficiency
Profiled Valve
The CSM system uses a profiled valve as part of the internal sealing arrangement, helping maintain dependable compressed-air performance during repeated connection cycles.
Nitrile Seal
A nitrile seal helps maintain connection tightness and contributes to the long sealing life of the coupling.
Efficient Airflow
Prevost identifies excellent flow capacity as an important contributor to pneumatic-system and tool efficiency, with airflow increasing substantially as ID Passage size increases.
Flow Capacity by ID Passage
| 1/4" ID Passage | 833 l/min at 6 bar with 0.6 bar Pressure Drop |
|---|---|
| 3/8" ID Passage | 2,120 l/min at 6 bar with 0.6 bar Pressure Drop |
| 1/2" ID Passage | 4,120 l/min at 6 bar with 0.6 bar Pressure Drop |
ISO 6150 C Compatibility
These CSM safety couplers use the ISO 6150 C quick-connect profile. The mating plug must correspond to the selected coupling profile and ID Passage family.
- Select the mating plug according to the CSM quick-connect family.
- Male NPT size does not determine which plug fits the coupler.
- Two couplers can have the same male NPT connection while using different quick-connect passage sizes.
- Verify the existing plug profile before ordering replacement or additional couplers.

Installation & Safety Guidance
- Depressurize the compressed-air system before installing, removing, or servicing threaded components.
- Verify the required ISO C profile and ID Passage before connecting pneumatic equipment.
- Confirm that the selected male NPT connection matches the female-threaded system fitting.
- Use thread-sealing materials and installation practices suitable for compressed-air NPT service.
- Do not select the coupling based only on male thread size.
- Verify that the selected ID Passage provides adequate airflow for the connected pneumatic equipment.
