Flexi Connector

Flexi Connector is made from an ether-based polyurethane with a fully encased 316 stainless steel wire coil. Ideal for compression applications like bag feeders, filling heads or bulk bag fillers.

Product Description

The Flexi-Connector is made from an ether-based polyurethane with a fully-encased 316 stainless steel wire coil supporting the body of the connector.

This helps to keep the aperture of the connector open and allows vertical movement without the product flow being compromised.

Ideal for bag feeders, filling heads or bulk bag fillers.

Application(s):

  • Used for vertical movement/compression applications
  • Ideal for bulk bag loading and filling

Frequently Asked Questions

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.
