PrevoS1 One-Button Safety Release
Prevost PrevoS1 technology uses a push-button safety system designed to provide decompression followed by disconnection. Relieving pressure before complete separation helps reduce sudden hose movement.
- Simple push-button operation
- Decompression before complete disconnection
- Helps reduce hose-whip risk
- Designed to help protect operators and nearby equipment
- Convenient for frequently connected compressed-air hoses and tools
Optimized Compressed-Air Flow
Reduced Turbulence
The PrevoS1 internal airflow design avoids a conventional valve spring in the airflow path, helping reduce turbulence through the coupling.
Efficient Air Delivery
Optimized flow helps minimize unnecessary pressure loss and supports efficient pneumatic-tool performance.
Profile Size, Hose ID & ID Passage
The Automotive profile size, hose ID, and internal passage are separate specifications and should all be verified before ordering.
- USI 061810 uses a 1/4" Automotive profile.
- USI 061810 connects to 3/8" ID hose.
- USI 061810 has a 1/4" ID passage.

|---|---|---|---|
| USI 061810 | 1/4" | 3/8" | 1/4" |
| USI 081813 | 3/8" | 1/2" | 3/8" |
Direct Hose Connection
The hose stem configuration allows the coupler to connect directly to compatible compressed-air hose without requiring a separate threaded hose adapter.
- Compact hose-end installation
- Reduces the number of separate fittings required
- Suitable for new hose assemblies
- Suitable for replacement hose-end couplers
- Useful for professional shop and industrial compressed-air hoses
Anti-Static & Silicone-Free
Anti-Static Design
PrevoS1 couplers are designed to help prevent static-electricity buildup in compressed-air systems.
Silicone-Free Construction
Prevost specifies PrevoS1 couplers as silicone free, helping reduce contamination in compressed-air systems used for paint, varnish, and finishing work.
Anti-Scratch, Light & Compact
Protective Body
The anti-scratch exterior helps protect finished or delicate surfaces when the hose-end coupler comes into contact with surrounding equipment or workpieces.
Compact Hose-End Design
The lightweight, compact construction helps reduce unnecessary bulk at the end of a compressed-air hose.
Easy Identification
Color-Coded Button
The colored push button helps operators identify the coupling profile from a distance and reduce connection errors.
Laser-Printed Part Number
The exact part number is laser printed on each coupler for easier identification during replacement, maintenance, and inventory work.

How to Select the Correct Hose Stem Coupler
- Step 1: Identify whether the mating plug uses the 1/4" or 3/8" Automotive profile.
- Step 2: For the 1/4" Automotive profile, verify that the hose ID is 3/8" and select USI 061810.
- Step 3: For the 3/8" Automotive profile, verify that the hose ID is 1/2" and select USI 081813.
- Step 4: Verify the hose pressure rating and material are appropriate for the compressed-air system.
- Step 5: Use an appropriate hose-retention method.
- Step 6: Confirm complete-system pressure, temperature, and flow requirements before installation.

Installation & Safety Guidance
- Depressurize the compressed-air system before installing or replacing the coupler.
- Confirm the Automotive profile before connecting a mating plug.
- Confirm hose inside diameter before installing the hose stem.
- Use compressed-air hose with an appropriate pressure rating.
- Secure the hose using a suitable clamp, ferrule, crimp, or other approved retention method.
- Never force an incompatible quick-connect plug into the coupler.
- Inspect the hose, hose connection, and coupler periodically for wear or damage.
- Replace damaged or excessively worn components.
- Do not exceed the operating limits of the coupler, hose, tool, or connected equipment.
- Compressed-air hose assemblies should be fabricated and serviced using appropriate professional practices.

Frequently Asked Questions
Which SKUs are included?
This listing contains USI 061810 and USI 081813.
What is USI 061810?
USI 061810 is a PrevoS1 hose stem safety coupler with a 1/4" Automotive profile, 3/8" hose ID connection, and 1/4" ID passage.
What is USI 081813?
USI 081813 is a PrevoS1 hose stem safety coupler with a 3/8" Automotive profile, 1/2" hose ID connection, and 3/8" ID passage.
What is the difference between the two models?
USI 061810 uses the 1/4" Automotive profile and is designed for 3/8" ID hose. USI 081813 uses the larger 3/8" Automotive profile and is designed for 1/2" ID hose.
Is hose ID the same as the quick-connect profile?
No. Hose ID determines which hose fits the stem, while Automotive profile determines which quick-connect plug fits the coupler.
What does the PrevoS1 push button do?
The push-button system provides decompression and disconnection, helping reduce hose-whip risk.
Are PrevoS1 couplers anti-static?
Yes. Prevost identifies anti-static design as a PrevoS1 feature.
Are PrevoS1 couplers silicone free?
Yes. Prevost specifies PrevoS1 couplers as silicone free.
Why choose a hose stem coupler?
A hose stem provides a direct connection between compatible compressed-air hose and the safety coupler, reducing the need for a separate threaded hose adapter.
