HG Power 3-Inch 16 ft Long Air Ducting – Flexible Nylon Duct for Diesel Heaters

Overview

Upgrade your diesel heater ventilation with HG Power's 3-inch nylon air ducting. Built for durability and flexible routing, this ducting helps channel warm air with precision in vehicles, campers, boats, and other compact spaces. The design blends reliability with practicality, making it a versatile choice for on‑the‑go setups.

Key Benefits

• High‑heat nylon construction resists softening and warping, even with prolonged exposure to warmth. It also offers about a 25% improvement in heat resistance compared with older PVC ducts.
• The woven nylon fabric is wear‑ and knot‑ resistant, with flexible bending and extending capabilities to fit tight routes or longer runs.
• Precise sizing supports compatibility: inner diameter up to ~80 mm and outer diameter ~85 mm, designed for most 3‑inch equipment; includes 2 stainless steel clamps for quick installation.
• Connection guidance: attach to the end of the exhaust pipe, not directly to the heater's hot air outlet, to ensure safe venting and proper airflow path.

Versatile Applications

• Delivers warm air to vehicles, vans, campers, and ship cabins, and can assist other 3‑inch exhaust devices for ventilation.
• Can function as an extension duct for additional heating or ventilation in snug or irregularly shaped spaces.

Specs & What’s Included

Max inner diameter: ~80 mm; outer diameter: ~85 mm. Free‑state ID/OD: ~2.5–2.6 inches, compatible with most 3‑inch equipment. The package includes two stainless steel clamps for secure installation.

Real‑World Use Considerations

The duct’s heat‑melt joints help maintain clean seams, while the high‑quality nylon construction supports long‑term use in mobile environments. With its flexible yet durable design, users can plan routing that minimizes bends while preserving airflow efficiency. While performance will vary by setup, the ducts are designed to offer practical flexibility for common diesel heating systems.
