Express Duct 45 Degree Bends

Express Duct 45 degree bends (often searched as a ducting elbow, ducting bend, or 45 degree ducting elbow) are part of the Express Duct clipped ducting range. They’re used when you need a 45° change of direction while keeping the same Express Duct connection style through the rest of the duct run.

This category includes sizes from 80mm to 500mm, including most popular options like a 100mm and 150mm 45 degree bends.

Important: This information is general. Selection depends on duct diameter, your existing ductwork and what you’re connecting into. If you’re unsure, speak to our team before ordering.

Key details

Type: Express Duct clipped 45 degree bend / ducting elbow

Sizing and compatibility (80mm–500mm)

Most customers choose their 45 degree bend by diameter first (for example 100mm or 150mm), then match it to the rest of the Express Duct run.

If you’re connecting Express Duct to another duct type (for example spiral ducting or a different ductwork system), adapter options are available, and if you tell us what you’re connecting to, we can point you to the right parts.

FAQ

What makes “Express Duct” 45-degree bends different from standard spiral bends?
Express Duct bends use the Express Duct clipped connection style, rather than a standard spiral ducting joint, so they’re selected to match the Express Duct system.

How does a 45-degree ducting elbow affect my system’s airflow?
Any bend changes airflow direction, and the impact depends on the wider duct layout and operating conditions. If you want a quick sense-check, share your duct sizes and layout and we’ll help you choose appropriate components.

What is the radius of these ducting elbows?
The bend radius is listed as R (Radius) = 1 × D (Diameter).

Can these ducting bends be used for heavy-duty materials like wood chips or abrasive powders?
Suitability depends on what’s being conveyed and the overall system specification. If you tell us what the system is handling, we can advise which components make sense.

Do I need sealant or screws for a 45-degree ducting elbow?
Express Duct components are designed to be clamped using quick clips/clamps (sold separately). Any additional sealing approach depends on the wider system and site requirements.

Are these ducting bends available in stainless steel?
The bends in this category are galvanised steel. If you need an alternative material, contact the team and we’ll check options.
