Alpine Corporation PVC Tubing 3/8-in ID 100 ft Black — Flexible, Fish-Safe for Ponds & Fountains

Alpine Corporation's 3/8" inside-diameter, 100-foot black PVC coil tubing is a flexible, fish-safe line engineered for routing water in ponds, fountains, waterfalls and many indoor or outdoor fluid applications.

This ultra-flexible PVC tubing combines long reach with a slim 3/8" inner bore so you can run pumps and filters far from water features without visible lines or bulky joints. The tubing is molded from black PVC with a 1/16" wall thickness that balances pliability and durability, and its non-toxic composition is formulated to be safe for aquatic life when submerged. Lightweight and coiled for easy storage, the hose is suitable for garden water circulation, HVAC and appliance overflow uses, and comes with a one-year manufacturer support period.

How does this tubing perform in pond and fountain systems?

The narrow 3/8" ID is ideal for connecting small- to medium-sized pumps and routed water returns, keeping flow consistent while remaining discreet underwater. The black finish reduces visual impact in ponds and landscaping, and the flexible construction allows smooth bends without kinking.

• 3/8" inside diameter for standard pump fittings and inline equipment
• 1/16" wall thickness for a balance of flexibility and toughness
• Black color minimizes visibility when submerged or behind rocks
• 100-foot coil for long runs or multiple installations from a single spool

Can this tubing be used for indoor or non-pond tasks like HVAC and humidifiers?

Yes — the tubing's PVC construction and continuous length make it useful for a range of household and light-industrial tasks where a small-diameter fluid line is needed. It resists common household moisture conditions and routes easily through tight spaces.

• Suitable for humidifier overflow lines and air-conditioning drain reroutes
• Flexible enough to follow bends and corners without fittings in many cases
• Non-toxic material that is safe for incidental contact with water systems
• 100' length eliminates multiple couplings for long-distance runs

How durable is the tubing, and how do I maintain it for long-term use?

The tubing is made from flexible black PVC with a single 1/16" wall designed to resist everyday wear, moderate abrasion, and UV exposure when used in typical pond and garden settings. Periodic inspection and simple maintenance extend service life and help avoid clogs or damage from debris.

• Inspect for cracks, punctures, or stiffness before each season
• Flush lines occasionally to remove sediment build-up and biofilm
• Avoid sharp bending over a small radius to prevent stress points
• Store the coiled tubing out of prolonged direct sunlight when not in use

What sizes, connectors, and warranty details should I plan for?

The coil measures 3/8" ID x 1/2" OD with a 1/16" wall and ships as a single 100-foot length, which fits many standard push-fit and barbed hose fittings. Use appropriate clamps or barbed adapters for secure joins, and note the product includes a one-year manufacturer's support window from the purchase date.

• Dimensions: 3/8" inner diameter, 1/2" outer diameter, 1/16" wall
• Length: 100 feet per coil for long runs or multiple runs
• Compatibility: common barbed fittings and clamps for secure joins
• Support: one-year manufacturer's assistance from date of purchase

Who is this for? Installers, hobbyist pond keepers and landscapers who need a discreet, long-lasting tubing solution will value the Alpine Corporation 3/8" x 100' black PVC coil. It's also a practical pick for homeowners routing humidifier overflow, AC drains, or other small-diameter fluid lines where flexibility, invisibility in water, and a long continuous run matter. Choose this tubing when you want a simple, adaptable line that reduces visible plumbing and handles a variety of garden and indoor fluid routing needs.
