PrevoS1 One-Button Safety Release
Prevost PrevoS1 technology uses a push-button system designed to provide decompression followed by disconnection. Relieving compressed air before the connection fully separates helps reduce sudden hose movement during disconnection.
- Simple push-button operation
- Decompression before complete separation
- Helps reduce hose-whip risk
- Designed to help protect operators and surrounding equipment
- Convenient for frequently connected pneumatic tools and hose systems
Optimized Compressed-Air Flow
Reduced Turbulence
The PrevoS1 internal design avoids placing a conventional valve spring directly in the airflow path, helping reduce turbulence as compressed air moves through the coupler.
Profile-Sized Air Passages
The USI 06, USI 08, and USI 11 families provide progressively larger 1/4", 3/8", and 1/2" ID passages to support compatible compressed-air applications.
Why Automotive Profile Size Matters
The Automotive quick-connect profile determines which mating plug fits the coupler. It is separate from the female NPT equipment connection.
- USI 06 uses a 1/4" Automotive quick-connect profile.
- USI 08 uses a 3/8" Automotive quick-connect profile.
- USI 11 uses a 1/2" Automotive quick-connect profile.
- A female NPT thread size does not determine the quick-connect profile.
- Two couplers can have the same female NPT size but use completely different quick-connect profiles.
- Always verify both specifications before ordering.
Understanding Female NPT Size
The female NPT connection attaches the PrevoS1 coupler to a compatible male threaded component.
- 1/4" Female NPT is available in the USI 06 and USI 08 families.
- 3/8" Female NPT is available in the USI 06, USI 08, and USI 11 families.
- 1/2" Female NPT is available in the USI 06, USI 08, and USI 11 families.
- 3/4" Female NPT is available on USI 111204EB in the 1/2" Automotive family.
Anti-Static Design
PrevoS1 couplers are designed to help prevent static-electricity buildup in compatible compressed-air systems. This can be useful in automotive finishing, painting, industrial production, and other environments where static control is important.
Silicone-Free Construction
Prevost specifies PrevoS1 couplers as silicone free. This helps reduce the risk of silicone contamination entering compressed-air lines used for paint, varnish, and finishing applications.
Anti-Scratch Protective Body
The protective PrevoS1 exterior helps reduce scratching when the coupler comes into contact with finished or delicate surfaces.
- Automotive body shops
- Vehicle service facilities
- Paint and finishing areas
- Assembly operations
- Woodworking facilities
- Manufacturing environments
Light & Compact Design
PrevoS1 couplers are designed for comfortable professional use with a compact body that helps minimize unnecessary bulk at compressed-air hoses, tools, machines, manifolds, and distribution points.
Easy Profile Identification
Color-Coded Button
Prevost uses button color coding to help operators identify the connection profile and reduce connection mistakes.
Laser-Printed Part Number
The part number is laser printed directly onto the coupling, making exact model identification easier during maintenance, replacement, and inventory work.

- Step 2: Select USI 06 for 1/4" Automotive, USI 08 for 3/8" Automotive, or USI 11 for 1/2" Automotive.
- Step 3: Identify the male NPT thread size on the hose fitting, regulator, manifold, machine, or pneumatic component.
- Step 4: Select the corresponding female NPT connection.
- Step 5: Verify the ID passage and required compressed-air flow.
- Step 6: Confirm pressure, temperature, hose, tool, and complete-system requirements before installation.

Installation & Safety Guidance
- Depressurize compressed-air equipment before installing, removing, or replacing a coupler.
- Confirm the Automotive quick-connect profile before connecting a mating plug.
- Confirm female NPT thread size before installation.
- Use thread-sealing material suitable for compressed-air NPT connections.
- Follow appropriate tightening practices and avoid overtightening threaded fittings.
- Never force an incompatible plug into the coupler.
- Inspect couplers periodically for excessive wear, damage, contamination, or deformation.
- Replace damaged or excessively worn components.
- Do not exceed the operating limits of the coupler, hose, pneumatic tool, or connected equipment.
- Compressed-air equipment should be installed and serviced by qualified personnel.
