How to use

Measure the required length and cut the hose with a sharp utility knife or hose cutter to achieve a clean, square end. Ensure mating fittings and connectors are clean and free of debris before assembly. Push the hose firmly onto 12/16 mm connectors or use appropriate clamps for a secure, leak-free connection. When routing the hose, avoid sharp bends and pinch points; maintain gentle curves to preserve flow and prevent kinks.

Usage recommendations

For long-term installations, secure the hose with clips or clamps at regular intervals and inspect periodically for signs of wear, biofilm buildup or discoloration. Replace sections that show permanent deformation or damage. Rinse new hose sections before first use to remove any manufacturing residues. Use hose clamps when connecting to pumps or pressurized fittings to minimize the risk of leaks.
