Description
This professional plastic ventilation end cap is designed to securely close off open duct ends within industrial and commercial ventilation systems. Manufactured from a durable, corrosion-resistant plastic, it provides a reliable seal that helps maintain system performance and protects duct interiors from dust, moisture and physical damage.
Ideal for use in factories, workshops, warehouses and plant rooms, this end cap is suitable for a wide range of circular ducting installations. Available in multiple outside diameters from 125 mm up to 250 mm and beyond, it offers a practical solution for terminating unused branches, finishing exposed duct runs and enabling easy future system modifications.
Product Features
- Available outside diameters: 125 mm, 160 mm, 200 mm, 225 mm, 250 mm and additional larger sizes
- Manufactured from robust, corrosion-resistant plastic for long service life
- High chemical resistance suitable for many industrial and process ventilation applications
- Designed for circular ducting systems in ventilation, extraction and air-handling installations
- Smooth internal and external surfaces for minimal airflow disruption and easy cleaning
- Push-fit style end closure compatible with standard plastic ducting components
- Lightweight construction for quick, easy handling and installation
Key Features and Benefits
- Provides a secure closure to open duct ends, helping to prevent ingress of dust, debris and pests.
- Corrosion-resistant plastic construction ensures reliable performance in humid or chemically aggressive environments.
- High chemical resistance makes it suitable for use with many fume extraction and process air systems.
- Multiple diameter options support both new installations and retrofits to existing ductwork.
- Simple push-fit design reduces installation time and labour costs compared with fabricated closures.
- Low-maintenance finish is easy to wipe clean, supporting good hygiene and housekeeping standards.

Frequently Asked Questions
How do I choose the correct size of ventilation end cap for my ducting?
Select the end cap by matching its outside diameter to the nominal size of your circular ducting. Check the duct’s stated diameter (e.g. 125 mm, 160 mm, 200 mm, 225 mm or 250 mm) and choose the corresponding cap size to ensure a proper fit.
Is this plastic end cap suitable for use in chemically aggressive environments?
The end cap is manufactured from a corrosion-resistant plastic with high chemical resistance, making it suitable for many chemically demanding environments. However, for specific chemicals or high concentrations, you should verify compatibility with the duct system designer or consult chemical resistance data for the plastic type used.
Can the end cap be removed and refitted if I want to extend the ducting later?
Yes, in most installations the push-fit design allows the end cap to be removed carefully if you wish to extend or modify the ductwork in the future. Take care not to damage the duct end during removal and ensure it is refitted securely if reused.
