Flexible Connectors

Seeflex 020E
Connector

Our lightest connector made of clear, lightweight ether based thermoplastic polyurethane alloy, mainly used for weigh-scale type applications.

Product Description

Seeflex 020E is a lightweight, flexible connector designed for applications where reduced weight and increased flexibility are key.

Made from a clear ether-based thermoplastic polyurethane alloy, it offers excellent durability while remaining highly pliable. It resists cracking from repeated flexing, ensuring long-lasting performance in demanding environments.

With superior wear resistance, Seeflex 020E outperforms traditional silicone, rubber, and other polyurethane connectors, providing a reliable, tear-resistant solution for various industries and applications.

Application

Perfect for lightweight applications such as weighing systems, vibratory feeders, and low-pressure conveying.
Ideal for applications where Seeflex 040E is not flexible enough.
The Seeflex 020E Connector is the thinnest Seeflex connector in the BFM^® range.

Tapered

Seeflex 020E is available as a tapered version where different entry and exit diameters are required.

Also often used as a simple hopper solution.
