Parametric Duct Adapter Generator – Custom Elbows, Reducers & Transitions

Make the connector your duct layout needs. This browser-based adapter generator lets you combine different connection shapes and sizes, change the bend angle and add an offset. It is useful when standard fittings do not match your DIY ventilation layout. Example configurations include: • A rectangular elbow between vertical and horizontal ducts. • A round-to-rectangular transition. • A reducer between different connection sizes. • An offset connector between misaligned ports. YOUR PROJECT. YOUR DIMENSIONS. YOUR ADAPTER. Explore countless configurations within the generator’s available settings. Choose the shape, size and male or female connection independently for each end, then adjust the angle, offset, approximate length and fit. Round sizes use diameter. Other shapes use maximum width, so inspect the resulting height and proportions in the preview before ordering. CUSTOMIZE ONLINE WITH A 3D PREVIEW Change the parameters directly in your browser and inspect the generated model. No CAD software installation is needed.

PRACTICAL FIT CHECK Measure both mating connections and allow space for insertion. Check the generated dimensions, test the fit and support the connected ducts separately. Material suitability and joint sealing depend on your application; the model does not establish a temperature or pressure rating.
