How to Choose the Right Connector for Your Weighing Application in Powder Processing

Accurate weighing is critical in powder processing. The right connector ensures that your weigh-scales deliver consistent, reliable results—without unnecessary downtime or calibration issues.

While many assume that a Weighing Bellows connector is always required, that’s not the case. Depending on your process, alternatives like Seeflex 040E, Seeflex 020E (with or without rings), and Flexi connectors may be more suitable.

So, how do you decide which BFM® fitting flexible connector is right for your specific weighing application?

In this quick video, we break down the most important considerations when selecting a connector for weighing applications in powder processing, such as:

• Whether you’re using loss-in-weight feeders

• How sensitive your scales are

• If your process requires breathability

• Whether you’re operating under pressure or vacuum

These factors all play a vital role in determining whether a Weighing Bellows connector—or an alternative BFM® connector—will deliver the best results.

Recommended Connectors for Weighing Applications

BFM® offers several specialist flexible connectors designed with weighing accuracy in mind:

• Seeflex 040E – a strong, transparent polyurethane connector suitable for many weighing setups.

• Seeflex 020E – thinner and lighter than Seeflex 040E, with options for use with or without rings.

• Weighing Bellows – designed specifically for highly sensitive weigh-scale applications.

• Flexi Connectors  – ideal where greater lateral flexibility is needed.
