Description
Prevost PrevoS1 Stainless Steel Safety Quick Hose Stem Coupler - 1/2" Industrial Profile
Prevost PrevoS1 Stainless Steel Safety Quick Hose Stem Couplers provide a rugged, high-flow connection between flexible compressed-air hose and compatible Industrial / ISO 6150 B plugs. These ISI 11 couplers use an 11 mm internal passage, stainless-steel body, and integrated hose stems for demanding pneumatic hose assemblies.
The PrevoS1 safety mechanism combines high airflow with controlled decompression and disconnection. One press of the release button first vents downstream pressure and then releases the plug, helping reduce hose-whip hazards during tool changes. The stainless-steel construction is intended for harsh industrial environments where impacts, dirt, moisture, corrosion resistance, and long service life are important.

Stainless-Steel Construction for Harsh Service
The ISI 11 metal-body PrevoS1 coupling uses a stainless-steel body with 17% chromium. Prevost designed this version for applications where couplings may be exposed to impacts, crushing, dirt, moisture, and other demanding operating conditions.
- Heavy-duty stainless-steel body
- Designed for demanding industrial use
- Suitable for dirty or damp environments
- Corrosion-resistant construction
- Well suited for mobile equipment and heavy industry
- Higher maximum service pressure than the composite ISI 11EB family
1/2" Industrial High-Flow Profile
Every coupler in this listing uses the same 11 mm / 1/2" Industrial quick-connect profile. Prevost publishes a flow rate of approximately 148 SCFM at 100 PSI with a 10 PSI pressure drop.
The hose stem size does not change the quick-connect profile. All four versions accept compatible IRP 11 Industrial plugs.
Direct Hose Connection
The integrated hose stem allows the coupling to connect directly to compatible flexible compressed-air hose without requiring a separate threaded hose adaptor.
- Select the hose stem according to the actual inside diameter of the hose.
- Push the hose fully onto the stem during assembly.
- Use a suitable clamp or approved hose-retention method.
- Verify the hose pressure and temperature ratings for the application.
- Hose size does not determine quick-connect plug compatibility.
Hose Stem Options
3/8" & 1/2" Hose
- ISI 111810: 3/8" hose ID
- ISI 111813: 1/2" hose ID
These configurations provide the ISI 11 high-flow Industrial profile for common flexible compressed-air hose sizes.
5/8" & 3/4" Hose
- ISI 111816: 5/8" hose ID
- ISI 111819: 3/4" hose ID
These larger hose-stem sizes are suited to higher-capacity hose assemblies where the 1/2" Industrial coupling profile is required.
One-Button Safety Disconnection
The PrevoS1 safety mechanism controls downstream pressure before the plug separates from the coupling. One press of the release button first decompresses the connected air line and then releases the plug.
This controlled sequence helps reduce sudden hose movement and hose whip during disconnection while providing fast and intuitive operation.
Safety & Performance Benefits
Controlled Disconnection
Automatic decompression before plug release helps reduce hose-whip hazards and uncontrolled hose movement.
High Airflow
The 11 mm passage provides approximately 148 SCFM under Prevost's published test conditions for demanding pneumatic equipment.
Heavy-Duty Durability
The stainless-steel body is designed for demanding environments where impact resistance and corrosion resistance are priorities.
Understanding Hose Size vs. Coupling Profile
The hose stem size and quick-connect profile describe two different parts of the coupler.
All variants in this listing use the same ISI 11 / 1/2" Industrial profile. The hose-stem dimension identifies the inside diameter of hose that connects to the rear of the coupler.
- ISI 111810: 1/2" Industrial profile x 3/8" hose stem
- ISI 111813: 1/2" Industrial profile x 1/2" hose stem
- ISI 111816: 1/2" Industrial profile x 5/8" hose stem
- ISI 111819: 1/2" Industrial profile x 3/4" hose stem
- All four use compatible IRP 11 Industrial plugs.
Industrial / ISO 6150 B Compatibility
These couplers use Prevost's ISI 11 Industrial / ISO 6150 B quick-connect profile and are designed to mate with compatible IRP 11 Industrial plugs.
- Use compatible IRP 11 plugs.
- Hose size does not determine plug compatibility.
- The mating plug must match the ISI 11 Industrial profile.
- Verify the existing quick-connect profile before ordering.

- Step 3: Determine the actual inside diameter of the compressed-air hose.
- Step 4: Select the matching 3/8", 1/2", 5/8", or 3/4" hose stem.
- Step 5: Use a hose and retention method appropriate for the system pressure and application.
- Step 6: Confirm the mating quick-connect plug is an IRP 11 Industrial plug.

- Match the hose stem to the actual inside diameter of the hose.
- Push the hose fully onto the stem before applying the retention device.
- Use a clamp or retention method appropriate for the hose material, diameter, pressure, and application.
- Verify that the mating plug uses the IRP 11 Industrial profile.
- Do not exceed the 232 PSI maximum service pressure.
- Keep operating temperature within the specified 5°F to 158°F range.
- Inspect the hose, stem, clamp, coupler, and plug periodically for wear, damage, loosening, or leakage.
- Replace damaged or excessively worn components.
- Compressed-air hose assemblies should be installed and serviced by qualified personnel.
