21656855 Air Hose | Genuine Volvo Penta Part

🔧 Product Description

Warm-air hose for the Volvo Penta cabin air heater in the 55 mm size, sold per metre, weighing 0.227 kg. This is the size matching the heater's standard 55 mm outlets, so it is the usual choice for a straight run off the heater body. The 50 mm hose is 21656854 and the 60 mm is 21656856; a high-flex 55 mm hose, 41103329, is listed as the alternative where the route is tight.
