Trelleborg transfers support for Boeing 737 MAX and 777X production to Casablanca
Date: 11.11.26
Trelleborg Sealing Solutions announces it is transferring its aerospace production supporting the Boeing 737 MAX and 777X to its new facility in the flourishing aerospace hub of Casablanca, Morocco.
Casablanca – a flourishing aerospace hub
Inaugurated in June 2026, the new 5,000 square meters/53,820 square feet state-of-the-art production facility in the strategic aerospace hub of Casablanca boosts capabilities and capacity for major customers like Boeing.

Gordon Roper, President Global Aerospace, says: “Casablanca’s development into a significant hub for aerospace led to Trelleborg developing Morocco’s first production facility focused on polymer seals for key aerospace customers.
“The transfer of our production supporting the 737 MAX and 777X is further evidence of our support for the region’s growing aerospace eco-system.”
Global expertise, local operations
Building on our long-standing relationship, Trelleborg signed a memorandum of understanding with Boeing two years ago. From Casablanca, Trelleborg will supply a range of aerospace sealing solutions including seals for airframes, nacelles and wings, which support the Boeing 737 MAX and 777X programs.
“Trelleborg has in recent years developed strategic regional investments that bring us closer to our key customers, increasing supply chain resilience,” adds Roper.

Ideally situated in Casablanca’s Midparc Industrial Freezone, close to Mohammed V International Airport, the new Trelleborg facility is creating 150 to 200 highly skilled jobs and is regarded by Moroccan authorities as an important step in accelerating the Kingdom’s integration into the global aerospace supply chain. Focused on high-value, technically demanding applications, the facility is fully integrated into Trelleborg global programs. The facility houses a fully equipped advanced material laboratory to support the ongoing testing and development of specialized materials for the global aerospace business.
Sealing solutions for aerospace
Trelleborg’s airframe seals are typically used for aerodynamic sealing of doors, canopies, hatches and panels, and Trelleborg is the largest global producer of aerospace window seals. These seals can be reinforced to provide the load, deformation and wear properties required for variable working conditions in both static and semi-static applications. They offer low friction, good abrasion resistance, high flexibility and long life, and can be combined with composite or metal structures to limit part count and ease installation.

Trelleborg also manufactures a range of components for functional and aesthetic interior aerospace applications such as storage bins, light fittings, and air conditioning nozzles and bezels. Materials are approved to all international smoke and toxicity standards and available in a range of standard and custom profiles. FDA- and NSF61-approved O-Rings are suitable for applications where seals come into contact with food or drinking water. Advanced extrusion technology is utilized for seat tracks, rub strips and gap seals, with materials color-matched to cabin interiors.
