Aquascape Black Vinyl Tubing is ideal for recirculating water in fountains and other water features without the use of PVC glue. Our non-toxic vinyl tubing is fish-safe, allowing for use in water features containing fish and plants. The durability of Aquascape Black Vinyl Tubing helps to prevent kinking while its flexibility helps to make installation quick and easy. Vinyl tubing works best when used with traditional stainless steel hose clamps and barbed fittings, forming water-tight seals.
