Alpine Corporation PVC Tubing 1/2" ID x 100' Coil — Black, Flexible Fish-Safe for Ponds & Fountains

Alpine Corporation's 100-foot, 1/2" inside-diameter flexible PVC tubing is a durable, fish-safe coil designed for ponds, fountains and a wide range of indoor and outdoor water or air routing needs.

This black, ultra-flexible PVC tubing combines long reach with a slim profile so it can be routed discreetly around water features or through tight appliance spaces. The tubing measures 1/2" ID x 5/8" OD with a 1/16" wall and comes in a 100-foot coil—long enough for complex pond plumbing, fountain returns, humidifier overflow lines, and many light-duty industrial or household applications. Its dark color reduces visibility underwater, and the PVC formulation is non-toxic and suitable for use around fish and aquatic plants.

How will this tubing perform in my backyard pond or fountain?

The tubing is designed for steady water routing rather than high-pressure pumping; its flexibility makes it easy to hide beneath rocks or under liners. Because it is black and slightly collapsible, it blends into submerged landscapes and reduces visual clutter while maintaining good flow for pumps within their recommended capacities.

• 1/2" inside diameter supports most small- to medium-sized pond and fountain pumps.
• 100' coil gives extra length for complex layouts or multiple runs.
• Black color minimizes visibility underwater for cleaner aesthetics.
• 1/16" wall balances flexibility and puncture resistance for typical garden use.

Is this tubing safe for fish, plants and other aquatic life?

The PVC is formulated to be non-toxic and appropriate for aquatic environments when used as intended. Unlike some untreated plastics, this tubing is suitable for routing water in ponds and water gardens where compatibility with fish and vegetation is important.

• Non-toxic PVC construction formulated for use near aquatic life.
• Dark tubing reduces visual disturbance in clear water habitats.
• Flexible material avoids sharp edges that can injure liners or plants during installation.

Can I use this tubing for indoor systems like humidifiers or air conditioning?

Yes — the tubing is versatile enough for many indoor plumbing or condensate lines where a 1/2" ID is acceptable. Its flexibility makes routing through narrow cabinets or along walls straightforward, and the long coil means you can cut multiple custom runs from one purchase.

• Suitable for humidifier overflow, condensate drains, and low-pressure HVAC lines.
• Cut-to-length convenience: use only what you need and store the remainder.
• Flexible coil conforms to tight spaces and reduces need for extra fittings.

How durable is the tubing and what warranty does it include?

The tubing features a 1/16" wall that provides resilience against everyday wear while keeping the tube soft enough to bend around obstacles. Alpine Corporation backs the product with a one-year manufacturer's support from the date of purchase for defects or initial concerns.

• 1/16" wall thickness for general-purpose durability and flexibility.
• Black PVC resists fading and stays discreet when submerged.
• One-year manufacturer's support included to address defects or early issues.

Who is this for? This 100' 1/2" ID PVC tubing is ideal for homeowners, pond and fountain hobbyists, landscape installers, and light commercial technicians who need a long, flexible, fish-safe line for routing water or condensate. If you need a discreet, easy-to-install tube for returns, overflows, or low-pressure lines and want the flexibility to cut custom lengths, this Alpine Corporation coil provides a practical, economical solution.
