Description
This premium 90° ventilation bend is designed for use with rigid ducting systems in demanding industrial, commercial and facilities-management environments. Manufactured from robust PPS (polyphenylene sulphide), it offers excellent dimensional stability and a precise 90-degree angle to help you change duct direction cleanly while maintaining efficient airflow.
Available in a wide range of outside diameters, this durable elbow fitting integrates seamlessly into new or existing ventilation pipework. Ideal for HVAC contractors, plant engineers and installers, it provides a reliable, heat- and chemical-resistant solution wherever high-performance ducting is required.
Product Features
- Premium 90° bend for use with compatible rigid ventilation ducting systems.
- Manufactured from high-performance PPS (polyphenylene sulphide) for enhanced durability.
- Available outside diameters: 63 mm, 75 mm, 90 mm, 110 mm, 125 mm (plus additional larger and intermediate sizes).
- Precisely moulded radius to promote smooth airflow and minimise pressure drop at directional changes.
- Suitable for integration into industrial, commercial and light process-ventilation systems.
- Consistent wall thickness and tight tolerances for a secure fit with matching pipework.
- Compatible with standard duct clamps, connectors and sealing methods used for PPS systems.
Key Features and Benefits
- High temperature resistance: PPS construction tolerates elevated operating temperatures, making the bend suitable for demanding process and extract applications.
- Excellent chemical resistance: Ideal for installations where vapours, fumes or cleaning agents are present, helping to extend system service life.
- Reliable airtight joints: Accurate dimensions support secure, well-sealed connections that help reduce leakage and maintain system efficiency.
- Improved airflow performance: The smooth internal bore and controlled bend geometry help limit turbulence and noise within the duct system.
- Versatile sizing options: Multiple outside diameters allow easy matching to existing duct runs and future system expansions.
- Low maintenance: Corrosion-resistant material and robust design reduce the need for frequent replacement or repairs.

Frequently Asked Questions
How do I select the correct size 90° ventilation bend for my ducting?
Match the outside diameter of the bend to the outside diameter of your existing rigid duct pipework. Check the system specification or measure the outside diameter of your duct with a suitable gauge, and choose the bend with the same nominal outside diameter. If you are unsure, consult your system drawings or speak to a qualified installer.
Is this PPS 90° bend suitable for high-temperature or chemically aggressive environments?
PPS offers very good resistance to elevated temperatures and many chemicals, making it well suited to demanding industrial and commercial applications. However, you should always confirm compatibility with the specific operating temperature, pressure and chemical exposure expected in your system before installation.
Can this bend be used with other duct materials, such as metal or different plastics?
The bend is designed primarily for use with matching PPS or compatible rigid duct systems of the same outside diameter. It may be connected to other materials using appropriate transition fittings, clamps and seals, provided that mechanical support, sealing and material compatibility are properly addressed by a qualified designer or installer.
