Express Duct 90 Degree Bends

They’re used when you need to change the direction of a duct run while keeping the connection consistent with the rest of your express duct system.

Important: This information is general. If you’re unsure which ducting bend is right for your setup, speak to our team before ordering.

Express Duct ducting elbows

These Express Duct ducting bends are manufactured in galvanised steel and supplied in a wide range of diameters. Key details:

• Type: Express Duct clipped 90 degree ducting bend / ducting elbow
• Material: Galvanised steel
• Radius: R (Radius) = 1 × D (Diameter)
• Diameter range: 80mm to 500mm (see product options below)
• Note: Quick clips sold separately

Sizing and compatibility: 80mm to 500mm diameters

Most customers choose their 90 degree bend by duct diameter first, for example, a 100mm 90 degree bend / 100mm ducting elbow, or a 150mm 90 degree bend / 150mm ducting elbow, then confirm it matches the rest of the Express Duct run.

If you’re joining Express Duct to another duct type, adapters are available for common connections (e.g. spiral ducting and flexible ducting).

Ducting bends and airflow: what to know

Any ducting elbow changes airflow direction, so the overall effect depends on the wider duct layout, airflow rate, and what’s being conveyed. If you’re planning a new run or modifying an existing one and want a quick sense-check on bend sizes and connections, give the team a call and we’ll help you select the right parts.

FAQ

What makes “Express Duct” 90-degree bends different from standard spiral bends?

Express Duct bends use the clipped/quick-clamp connection style of the Express Duct system, rather than standard spiral ducting joints.

How does a 90-degree bend affect my system’s airflow?

A bend introduces a change in direction, and the impact varies by system design and operating conditions. If you’re unsure, share your duct sizes and layout and we can help you choose appropriate components.

Can these bends be used for heavy-duty materials like wood chips or 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 Express Duct components make sense.

Do I need sealant or screws for these 90-degree elbows?

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.

What size 90-degree bend do I need?

Match the bend diameter to your ducting size (e.g. 100mm or 150mm) and the rest of the Express Duct run.

Are 90-degree bends available in stainless steel?

The Express Duct 90 degree bends shown in this category are galvanised steel. If you need an alternative material, contact the team and we’ll check options.

Is it better to use one 90-degree bend or two 45-degree bends?

Both approaches are used in ducting. The better option depends on space, layout, and airflow requirements. If you want to talk it through, we can help you select the right fittings for your run.
