Trelleborg acquires manufacturer of aerospace components

Trelleborg Group has, through its business area Trelleborg Sealing Solutions, signed an agreement to acquire an operation from the US-based privately owned 4M Company, Inc. The operation specializes in sealing solutions for aerospace and industrial applications.

The group’s head office and manufacturing are located in Tukwila, Washington, US, and it has annual sales of approximately SEK 85 M. This bolt-on acquisition is part of Trelleborg’s strategy to strengthen its positions in attractive industries.

“We are experiencing strong demand for aerospace seals with a continued positive trend for several years to come. The acquisition means we can increase our capacity to produce elastomers, used in various aerospace seals, and enables us to broaden our product range of, for example, conductive seals,” says Peter Hahn, President of the Trelleborg Sealing Solutions business area.

The transaction is expected to be finalized in the second quarter of 2023.
