3. Specifications

Note: Working pressure decreases with increasing temperature. Refer to product documentation for detailed pressure ratings at various temperatures.

4. Setup and Installation

Proper setup is crucial for the safe and efficient operation of the hose. Follow these guidelines:

1. Inspection: Before each use, visually inspect the entire length of the hose for any signs of damage, cuts, abrasions, kinks, or bulges. Check fittings for secure attachment and integrity. Do not use a damaged hose.
2. Compatibility: Ensure that the hose material (polyethylene) is compatible with the chemicals being transferred. Refer to chemical compatibility charts if unsure. Incompatible chemicals can degrade the hose, leading to leaks or bursts.
3. Fittings: Use appropriate fittings that are rated for the intended pressure and chemical type. Securely attach all fittings to the hose ends, ensuring a leak-free connection. Use hose clamps or crimp fittings as recommended by the fitting manufacturer.
4. Routing: Route the hose to avoid sharp bends, kinks, or areas where it might be pinched or abraded. Ensure there is sufficient slack to prevent strain on connections during operation.
5. Pressure Rating: Never exceed the maximum working pressure of 400 psi (at 70°F). Operating above this pressure can lead to hose failure and potential injury.

5. Operating Instructions

Follow these instructions for safe operation:

• Pressure Control: Gradually increase pressure when starting flow through the hose. Avoid sudden pressure surges. Monitor pressure gauges to ensure operation remains within the hose's rated working pressure.
• Temperature Considerations: Be aware that the hose's working pressure capacity decreases at higher temperatures. For example, the working pressure is 300 psi at 122°F. Adjust operating pressure accordingly based on fluid temperature.
• Chemical Transfer: When transferring chemicals, ensure proper ventilation and personal protective equipment (PPE) are used as required by the chemical's safety data sheet (SDS).
• Avoid Kinking: Do not allow the hose to kink during operation, as this can cause localized stress, reduce flow, and lead to premature failure.
• End of Use: After use, depressurize the hose system slowly and completely before disconnecting fittings.

6. Maintenance

Regular maintenance extends the life of your hose and ensures safe operation:

• Cleaning: After each use, especially with chemicals, flush the hose thoroughly with an appropriate cleaning agent or water to remove residual substances. Ensure the cleaning agent is compatible with the hose material.
• Storage: Store the hose in a cool, dry place away from direct sunlight, extreme temperatures, and ozone-generating equipment. Coil the hose neatly to prevent kinks and damage. Avoid storing with sharp objects or heavy items placed on top of it.
• Periodic Inspection: Conduct regular, thorough inspections of the hose for any signs of wear, cracking, blistering, or other damage. Pay close attention to areas near fittings. Replace the hose immediately if any damage is detected.
• Fitting Check: Periodically check the tightness and condition of all fittings. Replace worn or damaged fittings.
