HG Power 3-Inch Duct Hose — 8ft Flexible Nylon Air Ducting with Clamps

Meet the HG Power 3 Inch Duct Hose, a grey, flexible nylon air duct designed to channel warm air from a diesel heater to cabins, vehicles, and compact living areas. The 8 ft length provides reliable reach, while the 3 inch size pairs well with common heater connections for versatile installations.

This duct is built from woven nylon with heat-melt joints, engineered to resist deformation under sustained heat. Compared with older PVC designs, its heat resistance is enhanced by about 25%, helping maintain performance in demanding setups without compromising airflow or flexibility.

Durable, flexible, and easy to use

• Flexible nylon construction that resists wear, knotting, and cracking while bending to fit tight spaces
• Can be used as an extension hose when you need extra reach or varied routing

Specs and compatibility

• Max inner diameter 80 mm and outer diameter 85 mm; fits 3 inch equipment
• Length 8 ft; free-state ID/OD around 2.5–2.6 in

Installation and practical use
