"The reliability and performance of these seals makes them an invaluable choice for professionals who prioritise safety and precision in their aerospace endeavours."

the challenge

Inadmissible seepage of cryogenic and gaseous propellants through joints, leading to significant risks associated with the potential presence of ignition sources or sparks that could potentially lead to a disastrous failure of the vehicle and the endangerment of astronaut and/or ground crew lives.

the solution

Chosen for evaluation based on its -250°C to +260°C temperature capacity, the Astra Seal® underwent structural validation by enduring 240 pressure cycles at up to 2 times operating pressure while maintaining leak-prevention criteria.

the result

The Astra Seal® received certification for utilisation in numerous aerospace constructs.
