Wallas 3414 Hose Adaptor, 75 - 90mm

If your boat already has a factory-installed 90 mm hose system or you have a 90 mm hose system left over from an old heater, you can use this adapter to install your heater directly into it. The adapter works with a warm air hose, so remember to also get a piece of 75 mm hose. With this adapter, you can distribute air from the 75 mm hose system to the 90 mm hose to adjust the temperature in that space to a lower level. A heater with 90 mm hose outlets can also be connected to 75 mm hose systems with the adapter. In addition, the narrowing is used to increase the airflow when directing it to the windshield.
