Verify fitment before purchasing.
75mm Exhaust Pipe Ducting Set With Y Branch
This ducting set uses high-quality aluminum foil and ABS materials, offering high-temperature resistance and corrosion protection. The included Y Branch Connector allows warm air to be split to additional outlets, expanding venting options for existing heater systems. The front panel air vent is adjustable and can rotate 360° to place heat exactly where it is needed, enhancing overall comfort and system efficiency.
HDWS 75mm Ducting For Diesel Heaters
Designed for 2KW, 5KW, and 8KW diesel air heaters, this 75mm ducting uses high-quality aluminum foil, offering durability and corrosion resistance. The 360° rotatable air outlet panel can be removed for easy cleaning and direct airflow control, helping to maximize heater efficiency while keeping ducting secure and reliable during operation.
Eberspacher/Propex 360° Rotatable Vent Cover (60mm)
This vent cover is crafted from durable plastic with corrosion resistance and wear resistance. Its 360-degree rotation provides flexible airflow direction to targeted areas. Although compatible with various heater types, verify the 60mm sizing for your system to ensure a proper fit and surface protection against scratches and dust.
Copgge 2Pcs 75mm Vent Outlet Bundle
This dual-pack vent outlet is designed for 75mm warm air ducting and is compatible with Eberspacher/Webasto diesel heaters and similar Chinese models. The 75mm outer diameter sizing (2.95″) and 360° rotatable feature provide convenient airflow direction control. It helps replace worn outlets and protects heater surfaces from scratches and dust during operation.
TZUTOGETHER 75mm Warm Heater Duct Pipe
Specifically marketed for 2KW, 5KW, and 8KW diesel parking heaters, this 75mm ducting solution features a Y-type connector to separate hot air from the heater. It is designed to fit standard 75mm inner diameter ducts and supports straightforward installation and reliable operation within automotive heating systems.
ZTUOAUMA 75mm Y Shape Branch Connector
ABS plastic with flame-retardant features, this 75mm Y-branch connector includes two adjustable valve flaps to regulate air volume. It is compatible with Eberspacher, Webasto Propex, and other 75mm diesel parking heaters, helping to split airflow to multiple vents while maintaining control over heat distribution.
BuleVina 75mm Vent Outlet Connector With Regulating Valve
This valve-equipped 75mm vent outlet connector allows closeable, open regulation of airflow. It is suitable for 75mm inner diameter warm air ducts used by Webasto, Eberspacher, and similar diesel parking systems. The regulating valve helps direct heat efficiently and prevents unwanted airflow to other areas when needed.
Buying Guide: Key Purchase Considerations
- Compatibility: Confirm your heater model (Webasto, Eberspacher, Propex, etc.) and the duct size (most options use 75mm) before purchasing.
- Airflow Control: Look for 360-degree rotatable outlets for flexible direction of warm air and, if needed, Y-branch or valve features to split or regulate airflow.
- Material and Durability: Prioritize high-temperature resistant plastics or aluminum/ABS blends to resist heat, corrosion, and wear in vehicle environments.
- Installation Fit: Check inner and outer diameters, mounting port size, and any included clamps or fittings to ensure a proper fit with existing ducting.
- Surface Protection: Some vents offer dust and scratch protection to prevent damage to vehicle surfaces during operation.
- Multiple Outlets: For larger spaces, Y-branch or dual outlet configurations can improve heat distribution without overloading a single vent.
These considerations help compare options across brands and ensure that you select a venting solution that aligns with heater wattage, ducting layout, and vehicle constraints. Users should verify model compatibility with their specific diesel heater and vehicle before finalizing a purchase.
