Superior chemical resistance in quick couplings

Quick couplings are now extensively used in process lines to allow for a flexible production system and to make maintenance and repair quicker and easier.

Sealing issue:

A leading quick coupling manufacturer wanted to develop a coupling for use in the chemical and beverage industry. The elastomer seals that they usually fitted in their product would not stand up to the harsh conditions of these processing lines. They approached Trelleborg Sealing Solutions for a solution that would be chemical and steam resistant while complying with relevant industry standards.

Sealing requirements:

• High chemical resistance
• Withstand CIP chemicals and operate in superheated steam.
• Compliant with FDA and USP Class VI standards
• Tight tolerances

Solution:

Depending on cleaning regimes and process media, Trelleborg Sealing Solutions recommended O-Rings in either EPDM E7502 or Isolast®.

Result:

By using seals in these materials, quick couplings could be effectively cleaned and sterilized without causing deterioration of the O-Rings. This meant that the customers of the coupling manufacturer benefited from long component life.
