Description
This professional PVC ventilation end cap is designed to securely close off open duct ends in industrial and commercial ventilation systems. Manufactured from durable PVC with excellent chemical resistance, it provides a reliable seal that helps maintain system performance and protect internal ductwork from dust, debris and moisture.
Engineered for low air resistance and a smooth internal profile, this end cap supports efficient airflow management across a wide range of extraction, supply and process ventilation installations. Available in multiple outside diameters, it is ideal for use in factories, workshops, laboratories, plant rooms and other demanding environments where robust, low-maintenance duct fittings are essential.
Product Features
- Manufactured from robust PVC for long-lasting performance in industrial ventilation systems.
- Available in a range of outside diameters including 50, 63, 75, 90 and 110 mm, plus additional larger sizes for bigger duct runs.
- Designed for use with compatible round ventilation ducting and pipework.
- Smooth internal surface helps minimise turbulence and maintain low air resistance at duct terminations.
- Chemical-resistant construction suitable for many fume extraction and process air applications.
- Precision-moulded for a secure push-fit connection with appropriate PVC duct pipes.
- Easy to install and remove, allowing for future system changes, inspection or maintenance.
Key Features and Benefits
- Helps prevent dust, debris and contaminants entering unused duct lines, protecting internal duct surfaces and equipment.
- Supports efficient airflow by providing a clean, closed termination with minimal impact on system pressure.
- Excellent chemical resistance makes it suitable for use in environments handling fumes, vapours and process gases within the material’s compatibility range.
- Multiple diameter options allow simple integration into new or existing duct systems without complex adaptors.
- Low-maintenance PVC construction resists corrosion and general wear, reducing replacement and upkeep costs.
- Lightweight design simplifies handling and installation, particularly on overhead or hard-to-reach ductwork.

Frequently Asked Questions
How do I choose the correct size of PVC ventilation end cap for my ducting?
Select the end cap size that matches the outside diameter of your existing PVC duct or pipe. For example, a 110 mm outside diameter duct requires a 110 mm end cap. Always measure the actual outside diameter of the duct to ensure a secure push-fit connection.
Is this PVC end cap suitable for use with chemical fume extraction systems?
The end cap is made from chemical-resistant PVC and is suitable for many light to medium chemical fume applications. However, compatibility depends on the specific chemicals, concentrations and operating temperatures, so it is important to check PVC resistance data or seek technical advice for more aggressive environments.
Can the end cap be removed and reused if I need to extend or modify the duct system later?
Yes, the push-fit design allows the end cap to be removed carefully from the duct and reused, provided it has not been damaged and remains in good condition. This makes it a practical option for systems that may need future expansion or reconfiguration.
