The ID passage size and hose barb size describe two different parts of the coupler and should be selected independently.

The ID passage determines the internal airflow capacity and Industrial coupling family. The hose barb size identifies the hose inside diameter that the coupler is designed to connect to.

• ISI 06: 6 mm / nominal 1/4" internal passage
• ISI 08: 8 mm / nominal 3/8" internal passage
• ISI 11EB: 11 mm / nominal 1/2" internal passage
• Hose barb size should be matched to the inside diameter of the compressed-air hose.
• Do not assume the barb diameter must equal the coupler passage size.

Prevost prevoS1 couplers control the release of compressed air before the plug separates from the coupling. With one press of the release button, downstream pressure is first discharged and the connection is then released.

This controlled sequence helps reduce sudden hose movement and hose whip during pneumatic-tool changes while simplifying operation for technicians and production personnel.

These prevoS1 couplers use the Industrial / ISO 6150 B connection profile. Plug compatibility is determined by the coupling profile and ID passage family rather than by the hose barb size.

• ISI 06 corresponds to the 1/4" / 6 mm Industrial coupling family.
• ISI 08 corresponds to the 3/8" / 8 mm Industrial coupling family.
• ISI 11EB corresponds to the 1/2" / 11 mm Industrial coupling family.
• Use a compatible Industrial plug for the selected coupling family.
• Hose barb diameter does not determine plug compatibility.

• Step 1: Identify the required Industrial coupling family: ISI 06, ISI 08, or ISI 11EB.
• Step 2: Confirm that the passage provides enough airflow for the pneumatic tool or equipment.
• Step 3: Determine the inside diameter of the compressed-air hose.
• Step 4: Select the corresponding hose barb size.
• Step 5: Confirm that the mating plug matches the selected Industrial coupling family.
• Step 6: Use a hose and retention method appropriate for the pressure and service conditions.

• Depressurize the compressed-air system before installing, removing, or servicing hose connections.
• Match the hose barb to the actual inside diameter of the compressed-air hose.
• Use hose that is rated for the system pressure, temperature, and compressed-air service.
• Secure the hose to the barb using an appropriate clamping or retention method.
• Verify the required Industrial 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.
• Inspect the hose, clamp, barb, coupler, and plug periodically for wear, damage, contamination, or leakage.
• Replace damaged or excessively worn components.
• Compressed-air components should be installed and serviced by qualified personnel.
