All Healthy Lake flexible pond hoses are crafted from high-quality materials with a smooth internal diameter to minimize flow loss. The Black Medium Duty Hose features a virtually smooth exterior, while the Green/Black Heavy Duty Hose is partially ribbed to support its reinforced structure. Our premium hoses are designed to ensure a secure, leak-free fit when used with flat hose clips.

• Medium Duty Hose (Black): Suitable for submerged or above-ground use, with a maximum operating pressure of 3 bar.
• Heavy Duty Hose (Green/Black): Can also be buried underground and withstands up to 6 bar of pressure.
• All hoses are measured by internal diameter (e.g., 1 inch / 25mm ID).

Please note: We do not offer light-duty pond hoses (sometimes referred to as Aquatic Hose) due to their thin walls, which can become brittle over time, and their external spiral ribbing, which makes sealing with hose clips difficult.
