The plugs are made of solid steel, providing durability and resistance to damage.
Key features include:
- Designed for High Air Flow applications.
- Features 1/4" Male NPT Threads for secure connections.
- Constructed from Durable Solid Steel for enhanced longevity.
- Specifically intended for use with Prevost Safety Air Couplers.
- More resistant to physical damage than aluminum options.
Safety Information
For safe operation and to prevent injury or equipment damage, please observe the following safety guidelines:
- Compatibility: These safety air plugs are designed exclusively for use with Prevost safety air couplers, specifically part numbers ESI 071201 and ESI 071253. Do not attempt to use these plugs with non-Prevost couplers or couplers not designated as safety types.
- Pressure Ratings: Always ensure that the air pressure in your system does not exceed the maximum rated pressure for both the Prevost air plugs and the connected Prevost safety couplers. Refer to the specifications section for details.
- Inspection: Before each use, visually inspect the air plugs for any signs of wear, damage, or corrosion. Do not use damaged plugs.
- Secure Connection: Ensure the plug is fully and securely seated into the coupler before applying air pressure. An improperly seated plug can lead to sudden disconnection and potential injury.
- Disconnection: Follow proper procedures for disconnecting air lines to safely release pressure and prevent "hose whip." Prevost safety couplers are designed for safe, two-stage disconnection.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, such as safety glasses, when working with compressed air systems.
Setup
The Prevost ERP 076251 air plugs are designed for straightforward integration into your compressed air system. Follow these steps for proper setup:
- Identify Connection Point: Determine the air tool or hose that requires a 1/4" Male NPT threaded connection for an air plug.
- Prepare Threads: Apply an appropriate thread sealant (e.g., PTFE tape or pipe thread compound) to the 1/4" Male NPT threads of the Prevost air plug. This helps ensure an airtight seal and prevents leaks.
- Thread into Place: Carefully thread the air plug into the female NPT port of your air tool or hose. Hand-tighten first to avoid cross-threading.
- Tighten Securely: Using a wrench, tighten the plug until it is secure and an airtight seal is achieved. Do not overtighten, as this can damage the threads.
- Connect to Coupler: Once the plug is installed on your tool or hose, it is ready to be connected to a compatible Prevost safety air coupler (e.g., ESI 071201 or ESI 071253).
Note: Ensure all connections are clean and free of debris before assembly to prevent leaks and ensure optimal performance.
Operating Instructions
Operating the Prevost ERP 076251 air plug involves connecting and disconnecting it from a compatible Prevost safety air coupler. These plugs are designed for high-flow applications, ensuring efficient air delivery to your tools.
- Connecting the Plug:
- Ensure the air supply to the coupler is off or depressurized before connecting.
- Insert the quick-connect end of the Prevost air plug firmly into the Prevost safety air coupler.
- Push until you hear or feel a positive click, indicating the plug is securely latched.
- Gently pull on the plug to confirm it is locked in place before activating air pressure.
- Disconnecting the Plug (Two-Stage Safety Disconnection):
- Always ensure the air tool is no longer in operation and the air supply to the coupler is off.
- For Prevost safety couplers, pull back the sleeve of the coupler slightly (first stage). This action depressurizes the line between the coupler and the plug, preventing "hose whip."
- After the air is vented, pull the sleeve back fully (second stage) to release the plug.
- Remove the plug from the coupler.
Important: Always follow the specific operating instructions for your Prevost safety air coupler to ensure safe and proper disconnection.
Maintenance
Regular maintenance of your Prevost ERP 076251 air plugs will ensure their longevity and continued high performance. These solid steel plugs are designed for durability, but proper care is still essential.
- Cleaning: Periodically clean the plugs to remove dirt, dust, and debris. Use a clean cloth. For stubborn grime, a mild degreaser can be used, ensuring it is thoroughly wiped off afterward.
- Inspection: Regularly inspect the threads for damage, wear, or corrosion. Check the quick-connect end for any deformities or signs of excessive wear that might affect its ability to seal or latch securely with the coupler.
- Lubrication: While not typically required for the plug itself, ensure that the internal mechanisms of your Prevost safety air couplers are properly lubricated according to their respective manuals. This helps maintain smooth connection and disconnection.
- Storage: Store air plugs in a clean, dry environment when not in use to prevent corrosion and contamination.
- Replacement: If any plug shows significant signs of wear, damage, or if it no longer forms a secure, leak-free connection with the coupler, replace it immediately to maintain safety and system efficiency.
