Handle Higher Flow Rates With 3/4-Inch Flexible Pond Tubing

Aquascape Black Vinyl Tubing (19 mm / 3/4 in ID, 15.2 m / 50 ft) is a UV-resistant, flexible pond plumbing tube for mid-to-high flow applications in water garden and waterfall installations. The larger 19 mm bore handles the output of mid-range submersible pumps without the flow restriction that narrower tubing creates, making it appropriate for feeding biological filter units, connecting pumps to waterfall distribution bars, and routing water through longer horizontal runs.

Right-Sized Tubing for Mid-Range Pump Flow

Using undersized tubing on a pump rated above approximately 1,500 LPH (400 GPH) imposes friction losses that reduce effective head pressure and limit flow output at the delivery point. The 19 mm (3/4 in) bore is matched to mid-range Aquascape pond pumps and reduces friction loss substantially compared to 13 mm (1/2 in) tubing across the same run length. The 15.2 m (50 ft) roll provides a practical length for most residential water feature plumbing jobs.

How to Use

Cut the tubing to length with a sharp utility knife or pipe cutter. Push the cut end fully onto a 3/4 in barbed fitting and secure with a stainless hose clamp, torqued until snug. Avoid sharp bends; maintain a minimum bend radius of 15 cm (6 in) to prevent internal restrictions. Route and bury the tubing to protect it from UV exposure and physical damage. Replace any section that shows cracking, softening, or permanent kink deformation.

Ideal for connecting mid-range Aquascape pumps to biological waterfall filters, distribution manifolds, and water garden stream systems requiring 3/4-inch plumbing connections.
