Seeflex 040E Connector

Strong, versatile, flexible; superior wear resistance for multiple applications; ATEX Compliant.

Product Description

Seeflex 040E is our most popular and versatile product and it is used in a huge range of industries and applications.

It is made from a clear ether-based thermoplastic polyurethane alloy making it very strong and flexible, so it won't fracture as a result of constant flexing.

Its unique construction method also gives superior wear resistance and it won't tear and rip apart like many silicon, rubber or other polyurethane connectors.

Application(s):

  • Ideal for use on sifters, sieves, screeners, feeders, bin discharges,
    hoppers & conveyors.
  •  Safe for use in CIP and with a wide range of chemicals (is also available as an easily identifiable 'Wash Sleeve' stamped version)

Product Options

Steel Rings-white background-400x300px

Rings

Seeflex 040E is available with stainless steel or plastic support rings to help keep the walls of the connector open.

Ideal for vacuum applications or longer lengths.

Tapered connector-white background-400x300px

Tapered

Seeflex 040E is available as a tapered version where different entry and exit diameters are required.

Also often used as a simple hopper solution.

Tool Release in action

Tool Release

For added security, this option has a significantly firmer snap-band that makes it virtually impossible to remove by hand and requires a specially shaped tool.

BFM® Seeflex 060ES Quick Access Port - transparent background

Quick Access Port

A 56mm polyurethane thread 'port hole' with a stainless steel screw-in plug that is added to the wall of the connector. 

Allows fast, easy access to product flow for testing, sampling or adding small-volume ingredients.

The Quick Access Port is not currently 3A approved so the connector will no longer have 3A approval.

Wash Sleeve Connector and Dot-1

Wash Sleeve

Seeflex 040E is available with a clearly marked "Wash Sleeve" stamp on the front to help differentiate which connector should be used for your CIP process.

Frequently Asked Questions

What is the most appropriate connector media for abrasive products?

Seeflex 040E is very strong and has been used with sugar, crystallized lactose, aggregates etc. Installing with an internal flow correction system is an additional way to further improve the system and avoid undue abrasion.

Is Seeflex 040E suitable for outdoor use - ie. is it UV and water-resistant?

Seeflex 040E can be used outdoors. It has been proven for use in both the sun and water. Extended exposure to UV will cause the Seeflex 040E to turn a little yellow, but the media will not lose any strength or integrity.

Can Seeflex 040E be used with liquids?

Yes, although the BFM® fitting is designed to provide a 100% seal on powder applications, we do not make this statement with liquid. The Seeflex 040E works very well and is used in a number of applications, although there may also be the occasional very small leak (drips). The composition of the liquid would also need to be checked to ensure compatibility with Seeflex.

Will Seeflex 040E work with an ethanol application?

If the contact with the ethanol is permanent the Seeflex 040E is not suitable. If it is sporadic and low temperature then you should have no problem. You may need to run a few tests on the media to check the suitability, as it will depend on time and temperature of contact with the solvent and the application. Please contact one of our representatives to discuss this further.

Can Seeflex 040E be used in an application with animal fat?

Yes, although the fat may stain Seeflex 040E, and cause it to go a little yellow, the strength of the media will not be affected greatly.

 
Which BFM® connector would be the best solution to use to process a laundry soap product?

This will depend somewhat on what is in the laundry soap. In general the Seeflex 040E will work well. There is often Sodium Carbonate or Sodium salt which may start to break down the Seelfex over an extended period. Unilever in New Zealand run the BFM® fitting on soap product without issue.
