Description
Prevost CSM Metal Safety Quick Hose Stem Coupler - ISO 6150 C Profile
Prevost CSM Metal Safety Quick Hose Stem Couplers provide a rugged, safety-focused connection between flexible compressed-air hose and compatible ISO 6150 C plugs. This listing combines 1/4", 3/8", and 1/2" ID Passage coupling families with multiple integrated hose stem sizes for professional pneumatic hose assemblies.
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.

- Stage 1: Automatic decompression of the downstream hose.
- Stage 2: Safe disconnection of the coupling.
- Helps reduce sudden hose movement during disconnection.
- Provides a simple and intuitive connection and disconnection process.
- Flexible automated mechanism is designed for reliable repeated operation.
Heavy-Duty Metal Construction
Stainless-Steel Body
The CSM coupling body is manufactured from 17% chrome stainless steel, providing a durable metal housing for professional compressed-air applications.
- Resistant to abrasion
- Resistant to shock
- Resistant to crushing
- Resistant to vibration
- Resistant to corrosion
One-Piece Stainless-Steel Lock
The locking mechanism uses a 13% chrome stainless-steel one-piece lock. Combined with the profiled valve and nitrile seal, the design supports dependable connection integrity and long service life.
Direct Hose Connection
The integrated hose stem allows the CSM coupler to connect directly to compatible flexible compressed-air hose without requiring a separate threaded hose adaptor.
- Select the hose stem according to the actual inside diameter of the hose.
- Push the hose fully onto the stem during assembly.
- Secure the hose using a suitable screw clamp, ear clamp, or other approved retention method.
- Verify the hose pressure and temperature ratings before installation.
- Hose size does not determine quick-connect plug compatibility.

Understanding ID Passage vs. Hose Stem Size
The ID Passage size and hose stem size describe two different parts of the coupler and do not need to be the same nominal size.
The ID Passage determines the quick-connect family and internal airflow capacity. The hose stem size identifies the inside diameter of the flexible compressed-air hose that connects to the rear of the coupler.
- CSM 06: Nominal 1/4" ID Passage
- CSM 08: Nominal 3/8" ID Passage
- CSM 11: Nominal 1/2" ID Passage
- Hose stem size should be matched to the actual hose ID.
- Hose size does not determine quick-connect plug compatibility.
Hose Stem Options
1/4" & 3/8" Hose
A 1/4" hose stem is available with the CSM 06 family. A 3/8" hose stem is available with CSM 06, CSM 08, and CSM 11 passage families.
1/2" & 5/8" Hose
A 1/2" hose stem is available across the CSM 06, CSM 08, and CSM 11 families. A 5/8" hose stem is available with CSM 08 and CSM 11.
3/4" Hose
The CSM 11 / 1/2" ID Passage family includes a 3/4" hose stem for larger compressed-air hose assemblies.
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 through repeated connection cycles.
Nitrile Seal
A nitrile seal helps maintain connection tightness and contributes to long sealing life.
Efficient Airflow
Prevost identifies excellent airflow as an important contributor to pneumatic-system and tool efficiency, with capacity increasing substantially across the three ID Passage families.
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.
- Hose stem size does not determine which plug fits the coupling.
- Different CSM passage families may use the same hose size while requiring different mating plug profiles.
- Verify the existing plug profile before ordering.

Installation & Safety Guidance
- Depressurize the compressed-air system before assembling, removing, or servicing hose connections.
- Match the hose stem to the actual inside diameter of the compressed-air hose.
- Push the hose completely onto the hose stem before securing it.
- Use a screw clamp, ear clamp, or other retention method suitable for the hose construction and application.
- Verify the required ISO C quick-connect profile and ID Passage before connecting equipment.
- Do not select a coupler based only on hose size.
- Verify that the selected ID Passage provides adequate airflow for the pneumatic equipment.
- Keep the coupling within its specified operating-temperature range.
- Inspect the hose, clamp, coupler, and mating plug periodically for wear, damage, corrosion, loosening, or leakage.
- Compressed-air hose assemblies should be installed and serviced by qualified personnel.
