CYDZSW 75mm/3inch Diesel Engine Parking Heater Duct Vent Outlet
Material And Dimensions: Manufactured from high-temperature resistant plastic with a 71mm internal mounting diameter and a 75mm outer mounting diameter. The air outlet face measures 99mm across and the overall height is 75mm.
Adjustability: The outlet rotates through 360 degrees, enabling directed warm air to a specific area of the cabin without additional redirection accessories.
Durability And Fit: Corrosion-proof and odor-free material is specified, and suitability relies on verifying the 75mm duct size for your heater model before purchase.

Kit Contents: Includes an extendable air duct hose (600–700mm), a 1″ stainless steel exhaust pipe, two outlet ducts, clamps, two air vent connectors and a tee connector to support common installation layouts.
Construction: The airflow duct uses a black film exterior for light resistance and an aluminum foil interior for high-temperature durability. The exhaust pipe is stainless steel for rust resistance.
Compatibility: Intended for 2KW/5KW/8KW diesel heaters, both split and all-in-one types. The extendable ducts are useful for custom routing where fixed-length ducts would not reach.
75mm Ducting Pipe Air Heater Valve Outlet Connector
Regulating Valve: Features a closeable/open regulating flap designed to control warm airflow through a 75mm duct. The valve allows you to direct or fully close an outlet to prioritize other vents.
Fit And Application: Designed to fit 75mm warm air ducts and Y/T branch connectors. The product listing emphasizes confirming compatibility with Eberspacher, Webasto and similar systems before purchase.

Use Case: Useful in multi-outlet systems where balancing airflow or isolating a branch is required during installation or maintenance.
ZTUOAUMA 75mm 5-Gear T-Piece Diesel Heater Duct Valve
Flow Control Design: The 5-gear regulator button and internal valve flap let you vary airflow distribution between left and right outlets. This enables proportional control or full shutoff of one branch.
Compatibility And Models: Marked compatible with Eberspacher, Webasto and Propex heaters in the 2KW–8KW range using 75mm ducts.
Application: Best suited when you need controlled split airflow in cabins, campers or boats where even distribution or variable output between zones is required.
DTNESS 75mm Auto Heater Pipe Ducting 9Pcs Kit
Package And Components: The kit contains 2 warm air ducts, 2 heater vents, 4 hose clamps and a T-shaped tee. The ducts have a 75mm inner diameter suitable for common diesel heater systems.
Vent Features: The vents rotate 360 degrees and the front panel is removable for screw-mount installation, providing flexible routing and installation options.
Materials: The ducts use high-temperature-resistant aluminum foil construction to resist corrosion and flame, while clamps and tee provide basic branching capabilities.
Buying Guide: How To Choose A Diesel Heater Window Vent Or Ducting Kit
Compatibility With Heater Model: Confirm your heater’s warm air duct inner diameter (commonly 75mm for many Webasto/Eberspacher/Propex units). Mismatch in duct diameter is the leading cause of installation issues.
Material And Temperature Resistance: Look for components made from high-temperature-resistant aluminum foil, ABS or flame-retardant plastics for the vents and stainless steel for exhausts. These materials resist heat, corrosion and aging.
Vent Adjustability: 360-degree rotatable vents allow precise air direction. Regulating flaps, multi-gear valves and closeable outlets let you balance airflow between branches and zones.
Kit Completeness: Determine whether you need a full ducting kit (hoses, tee connectors, clamps, exhaust pipe) or a single vent/valve. Kits are useful for complete installations; standalone vents are suitable for replacements.
Exhaust Safety And Routing: Exhaust pipes must be rust-resistant and routed to prevent heat buildup near combustible materials. Stainless steel exhaust sections are preferred for corrosion resistance.
Installation Ease: Consider whether front panels are removable for screw-mounting and whether the kit includes appropriate hose clamps and connectors. Extendable ducts simplify routing through tight or variable spaces.
Airflow Control Options: Manual valves (closeable flaps) and multi-gear regulators provide different levels of control. Use valves for simple on/off isolation and gear regulators where proportional distribution is required.
Durability And Maintenance: Select products with corrosion-proof materials and replaceable parts where possible. Easy disassembly of vents and clamps helps with cleaning and inspection.
Noise And Flow Characteristics: Rigid or semi-rigid ducts can transmit more noise than insulated flexible ducts. If cabin noise is a concern, consider flexible hoses with internal damping or routing choices that minimize vibration transfer.
Space And Mounting Constraints: Measure the available mounting depth and outlet placement before buying. Some vents have larger faceplates or require a specific mounting depth to seal properly.
Multiple Comparison Perspectives:
- Performance vs. Cost: Kits like VEVOR and DTNESS provide a balance of components for full installs, while standalone vents like CYDZSW are cost-effective replacements.
- Control vs. Simplicity: If you need simple on/off control, choose closeable valves; for graded distribution, select a multi-gear regulator.
- Durability vs. Weight: Stainless and metal parts increase durability but add weight; plastic and aluminum-foil hoses reduce weight while remaining heat-resistant.
Installation Tips: Always verify sizing before cutting or drilling. Use quality hose clamps and seal joints to avoid air leaks. Route exhaust at a safe distance from fuel and heat-sensitive components and secure hoses to prevent vibration wear.
