Frequently Asked Questions

How do I choose the correct gasket size for my ventilation pipe?

Select the gasket based on the outside diameter of the pipe or fitting you are sealing. Match the pipe’s outside diameter (for example 50 mm, 63 mm, 75 mm, 90 mm or 110 mm) to the corresponding gasket size listed, ensuring a snug fit without excessive stretching.

Is this PVC ventilation gasket suitable for use with chemical or fume extraction systems?

The gasket offers high chemical resistance and is suitable for many light fume and general extraction applications. However, for aggressive or highly corrosive chemicals you should check the chemical compatibility of PVC with the specific substances present in your system before installation.

Can the gasket be reused if the ventilation system is dismantled?

For best performance and to maintain an airtight seal, it is recommended to fit a new gasket whenever a joint is dismantled and reassembled. Reusing gaskets can compromise sealing effectiveness due to deformation or wear.
