High-Reliability Elastomers for Critical Missions
Aerospace and defence applications demand uncompromising reliability. We manufacture high-precision elastomer components that perform consistently under extreme temperatures, pressure variations, vibration, and demanding operating environments.
Overview
In aerospace and defence, a single seal can determine whether an entire system performs. Our moulded elastomer seals are engineered for the extremes these applications demand wide temperature cycling, high pressure and vacuum, aggressive fuels and hydraulic fluids, ozone and UV exposure, salt spray, humidity, and desert conditions.
We manufacture precision O-rings, gaskets, diaphragms, and custom-moulded components in high-performance elastomers including FKM, FFKM, Fluorosilicone (FVMQ), HNBR, and Viton Extreme, selected to suit each application's service environment. Because we compound in-house, materials can be developed and qualified against the specific standard your programme requires.
Every part is produced to tight tolerances with full material traceability, supporting the documentation and lot-control requirements that aerospace and defence procurement demands. From prototype through to production, our engineering team works alongside yours on material selection and component design.
From aggressive hydraulic fluids and fuels to extreme temperature cycling, our aerospace materials are formulated, mixed, and qualified in-house so we can develop to your specification rather than search a catalogue for something close.
