Sealed Bearingsby size

Aerospace seals have to withstand high and low temperature extremes, high pressures, and the risk of chemical degradation from aggressive hydrocarbons and de-icing and cleaning agents.

O-rings in aerospace applications are used to prevent leakage in shafts and cylindrical components, and to prevent environmental contaminants entering the seal assembly and cross-contamination of fluids within the assembly.

Seals used in the aerospace industry have to deliver high performance with high reliability, and as such they have to be manufactured from specialised materials.

Depending on the environment, silicones, EPDMs, and fluorinated polymers like FKM can be good candidates for an aerospace O-ring, gasket, or custom component.

In critical applications where seal failure puts life at risk, such as aviation, the right material specification is critical.

These critical roles make the correct material specification very important, with resistance to temperature extremes and chemical environments among the key attributes required from an aerospace seal.

For naval equipment, PPE offers a complete range of Def. Stan. 02-337 (NES 337) materials accepted by the UK Ministry of Defence, for use on surface ships, submarines, and their associated systems and equipment.

However, for full peace of mind in any operating environment, perfluoroelastomers (FFKMs) like Perlast® combine peak performance and reliability.

In such environments, elastomer seals made from perfluorocarbons (FFKMs) offer the best long term sealing performance and the lowest cost of ownership.

In addition to O-rings or custom profiles for aerospace sealing requirements, PPE manufactures NES 337 seals for critical naval defence applications.

Some elastomer materials can retain excellent sealing effect under extreme temperatures and pressures, and against exposure to aggressive chemicals.
