PTFE engineered seals

The aerospace and aviation industry is a rapidly growing international market serving millions of people every day. To protect human life, planes and jets must be made with reliable parts and perform to the highest standards under extreme conditions. One of the most critical aircraft parts is the aircraft seal, which prevents gasses and liquids from flowing or leaking between various components. These seals must be resistant to corrosion, temperature extremes, and high pressures.
