The vent is 360° rotatable, allowing warm air to be directed to the desired area. Suitable for 75mm ducting in Webasto, Eberspacher, and Propex heaters. Confirm compatibility before purchase.
75mm Exhaust Pipe Ducting Set
Features: Made of high-quality aluminum foil and ABS materials designed for high temperatures and corrosion resistance. Includes a Y Branch Connector to split warm air to multiple outlets. The air vent front panel rotates 360° for flexible directing of heat. Durable construction for Webasto/Eberspacher Propex systems.
HDWS 75mm Diesel Heater Ducting
Features: Designed for 2KW, 5KW, and 8KW diesel heaters. Inner duct diameter is 75mm; aluminum foil offers high-temperature and corrosion resistance. Includes a T-connector for integration with existing ductwork. The 360° rotatable front panel enables directing warm air precisely where needed.
Eberspacher/Propex 360 Rotatable Vent Cover (60mm)
Features: 360-degree rotatable air outlet for flexible airflow direction. Made from durable plastic with protective finish to reduce surface wear. While this option centers on a 60mm size, it demonstrates the rotatable vent concept applicable to similar 75mm systems when adapting components. Verify model compatibility before purchase.
Copgge 75mm Warm Air Vent Outlet (2 Pack)
Features: 75mm vent outlets compatible with 75mm warm air ducting. Includes 2 outlets for extended routing. 360° rotatable to control airflow direction, improving heater efficiency and reducing surface exposure to heat.
TZUTOGETHER 75mm Warm Heater Duct Set
Features: Primarily aimed at 2KW, 5KW, 8KW diesel parking heaters. Includes Y-type connector to separate hot air from the heater and route it through multiple outlets. Uses 75mm inner diameter ducting with a Y-branch design to maximize outlet options and airflow control.
ZTUOAUMA 75mm Y Shape Branch Connector
Features: ABS plastic Y-branch air vent with flame-retardant inside. Compatible with Eberspacher/Webasto/Propex 75mm air diesel parking heaters. Includes 2 adjustable valve flaps to control air volume, preventing over-venting and allowing precise distribution.
BuleVina 75mm Duct Outlet Connector
Features: Suitable for 75mm inner diameter tubes and compatible with Webasto and Eberspacher diesel parking systems. Includes a regulating close/open valve to direct airflow or close off one path to increase circulation through other vents. Emphasizes proper fit and ease of use for DIY installations.
Buying Guide
- Compatibility: Confirm the heater model (Webasto, Eberspacher, Propex) and the duct inner diameter (75mm is common) before purchasing any vent or connector.
- Airflow control: Look for 360° rotatable outlets and, if possible, Y-branch connections to distribute heat to multiple zones without compromising performance.
- Materials and durability: Choose vents made from high-temperature plastics or aluminum/foil composites that resist heat, corrosion, and wear in vehicle conditions.
- Installation footprint: Consider the mounting space, required mounting ports, and whether clamps or additional adapters are included or needed.
- Safety and protection: Prefer vents with protective surfaces to prevent scratches on interior surfaces and to minimize dust ingress.
- Multi-pack options: For larger or multi-zone heating, select multi-pack vent outlets with versatile rotation and multiple outlets to simplify routing.
