Frequently Asked Questions

Title Line
What is the maximum vacuum Flexi Connectors can handle?

100mm (4"): 0.10 bar 150mm (6"): 0.07 bar 200mm (8"): 0.06 bar 250mm (10"): 0.06 bar 300mm (12"): 0.02 bar

Would a Seeflex 040E connector with rings or a Flexi connector be more appropriate for dust collection on a Sweco with a vacuum?

A Seeflex 040E with rings will be more resilient to the vacuum than the Flexi. You could also use TR for extra resistance. Try and keep the connector as short as possible, and small gaps between rings.
