Plate Seals – Aerospace & Defence Sealing Solutions
Ashton Seals supplies high-performance plate seals engineered for use in demanding aerospace, defence, and industrial applications. These innovative sealing solutions are designed to deliver reliable static sealing performance while simplifying assembly and improving overall system efficiency. Unlike conventional sealing methods, plate seals are designed to separate the functions of sealing and tightening, allowing for improved load distribution, enhanced durability, and easier installation in complex assemblies.

Advanced Plate Seal Design & Performance
Aerospace plate seals are engineered to operate in extreme environments where reliability is critical. Their design offers several performance advantages:
- Separation of sealing and fastening functions for improved assembly efficiency
- Enhanced mechanical strength and durability
- Reduced wear and extended service life
- Lightweight construction without compromising performance
- Suitable for extreme temperatures and demanding operating conditions
A wide choice of rubber compounds and substrate materials ensures compatibility with specific aerospace and defence requirements.
