Bend Radius: Respect the minimum bend radius recommended by the manufacturer to prevent kinking or undue stress on the hose.

Avoid Sharp Bends: Sharp bends can cause the hose to kink or collapse internally, restricting flow and potentially causing damage.

Handling and Storage

Proper Handling: Avoid pulling or dragging the hose over sharp objects or rough surfaces to prevent abrasion and cuts.

Storage Conditions: Store hoses in a clean, dry environment away from direct sunlight and extreme temperatures, as prolonged exposure can degrade the materials.

Coiling for Storage: When not in use, coil the hose loosely to avoid kinks and twists, and store it in a way that does not put stress on the fittings.

Cleaning and Decontamination

Regular Cleaning: After use, especially if the hose has been exposed to aggressive chemicals, clean it with appropriate solvents or detergents that are compatible with PTFE.

Thorough Rinsing: Rinse the hose thoroughly with clean water to remove any residual cleaning agents or chemicals.

Drying: Allow the hose to dry completely before storage, as trapped moisture can lead to corrosion of the braiding or fittings.

Avoid Excessive Pressure and Temperature

Operational Limits: Always use the hose within the specified pressure and temperature ranges provided by the manufacturer.

Preventive Replacement: Consider replacing hoses before they reach the end of their expected service life, especially in critical applications.

Training and Documentation

Staff Training: Ensure that all personnel handling the hoses are trained on proper usage, maintenance, and safety procedures.

Record Keeping: Keep records of installation dates, maintenance activities, and any repairs or issues for each hose, as this helps in predicting lifespan and planning for replacements.
