• 1/4" ID passage
• Threaded swivel connection
• PrevoS1 push-button safety release

The larger USI 08 threaded swivel coupler uses the 3/8" Automotive quick-connect profile with a 3/8" ID passage.

• USI 081202SW: 3/8" Automotive Profile x 3/8" Female NPT Threaded Swivel
• 3/8" ID passage
• 3/8" female NPT equipment connection
• Threaded swivel design
• PrevoS1 push-button safety release

The threaded swivel configuration provides additional freedom of movement at the equipment-side connection compared with a fixed coupler. This can be particularly useful when pneumatic tools or hoses move frequently during operation.

• Provides additional movement at the threaded connection
• Helps reduce hose twisting
• Can help reduce strain at fittings and connections
• Useful for frequently repositioned pneumatic tools
• Useful for mobile compressed-air hose assemblies
• Retains the PrevoS1 safety-release functionality

Prevost PrevoS1 technology uses a push-button safety system designed to provide decompression followed by disconnection. Relieving compressed air before complete separation helps reduce sudden hose movement.

• Simple push-button operation
• Decompression before complete disconnection
• Helps reduce hose-whip risk
• Helps protect operators, tools, and nearby equipment
• Convenient for frequently connected pneumatic equipment

The Automotive profile, female NPT size, and ID passage describe different parts of the threaded swivel coupler.

• The Automotive profile determines which mating quick-connect plug fits the coupler.
• The female NPT size determines which threaded component the swivel connects to.
• The ID passage describes the internal airflow opening.
• USI 061201SW and USI 061202SW use a 1/4" Automotive profile and 1/4" ID passage.
• USI 081202SW uses a 3/8" Automotive profile and 3/8" ID passage.
• Always verify all three specifications before ordering.

PrevoS1 couplers are designed to help prevent the buildup of static electricity. This feature can be useful in compressed-air applications involving painting, finishing, manufacturing, and other environments where static control is important.

Prevost specifies PrevoS1 couplers as silicone free. This helps reduce the possibility of silicone contamination entering compressed-air systems used during painting and varnishing applications.

The protective PrevoS1 body helps reduce scratching if the coupler contacts finished or delicate surfaces.

• Automotive body shops
• Vehicle service areas
• Paint and finishing operations
• Assembly lines
• Woodworking facilities
• Manufacturing environments

PrevoS1 couplers are designed to be light and compact for comfortable professional use. The compact design helps limit unnecessary bulk while the swivel connection provides additional flexibility at the hose or equipment connection.

• Step 1: Identify whether the mating quick-connect plug uses the 1/4" or 3/8" Automotive profile.
• Step 2: Select a USI 06 model for 1/4" Automotive or USI 081202SW for 3/8" Automotive.
• Step 3: Identify the male NPT thread size on the hose fitting, equipment, manifold, or pneumatic component.
• Step 4: Select USI 061201SW for 1/4" female NPT.
• Step 5: Select USI 061202SW or USI 081202SW for 3/8" female NPT based on the required Automotive profile.
• Step 6: Confirm ID passage and compressed-air flow requirements.
• Step 7: Verify pressure, temperature, hose, tool, and complete-system requirements before installation.

• Depressurize compressed-air equipment before installing, removing, or replacing the coupler.
• Confirm the Automotive quick-connect profile before connecting a mating plug.
• Confirm female NPT thread size before installation.
• Use thread-sealing materials suitable for compressed-air NPT connections.
• Follow appropriate tightening practices and avoid overtightening.
• Allow adequate clearance for the swivel assembly to move as intended.
• Do not restrict or bind the swivel connection.
• Never force an incompatible quick-connect plug into the coupler.
• Inspect the coupler and swivel assembly periodically for wear, damage, or contamination.
• Replace damaged or excessively worn components.
• Do not exceed operating limits of the coupler, hose, pneumatic tool, or connected equipment.
• Compressed-air components should be installed and serviced by qualified personnel.
