The ID passage size and female NPT thread size describe two different parts of the coupler. They do not need to be the same size.

The ID passage determines the internal airflow capacity and Industrial coupling profile. The female NPT size determines the threaded inlet used to attach the coupler to a hose fitting, manifold, regulator, piping outlet, or other compressed-air component.

• ISI 06: 6 mm / nominal 1/4" ID passage
• ISI 08: 8 mm / nominal 3/8" ID passage
• ISI 11EB: 11 mm / nominal 1/2" ID passage
• Each passage family is offered with specific female NPT connection options.
• Always verify both passage size and female thread size before ordering.

Prevost prevoS1 couplers are designed to control the release of compressed air before the plug separates from the coupling. With one press of the button, the downstream air line is first decompressed and the connection is then released.

This controlled sequence helps reduce the risk of sudden hose movement associated with disconnecting a conventional compressed-air coupling while pressure remains trapped in the downstream hose.

These couplers use the Industrial / ISO 6150 B connection profile. Plug compatibility is determined by the coupling profile and passage family rather than by the female NPT inlet thread.

• 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 plug from the corresponding Industrial profile family.
• Do not assume couplers are interchangeable simply because their NPT thread sizes match.

• Step 1: Identify the required Industrial passage/profile family: ISI 06, ISI 08, or ISI 11EB.
• Step 2: Confirm that the selected passage provides sufficient airflow for the pneumatic tool or equipment.
• Step 3: Select the female NPT inlet size required by the hose, fitting, manifold, regulator, or piping connection.
• Step 4: Confirm that the mating plug matches the selected Industrial coupling family.
• Step 5: Verify pressure, temperature, airflow, and installation requirements for the complete compressed-air system.

• Depressurize the compressed-air system before installing, removing, or servicing threaded components.
• Verify the required Industrial profile and ID passage size before connecting equipment.
• Confirm that the selected female NPT thread matches the system connection.
• Use thread-sealing materials and installation practices suitable for compressed-air service.
• Do not select a coupler based only on female NPT thread size.
• Verify that the selected ID passage provides adequate airflow for the connected pneumatic equipment.
• Do not exceed the ratings of the coupling, hose, piping, fittings, or connected equipment.
• Inspect couplers and plugs periodically for wear, damage, contamination, or leakage.
• Replace damaged or excessively worn components.
• Compressed-air components should be installed and serviced by qualified personnel.
