PTFE Aerospace Seals

Finding the right sealing solution for aerospace applications involves a host of considerations, especially when it comes to the jacket material. However, there is one high-performance solution that rises to the top over and over: PTFE aerospace seals. 

Aerospace Seal Challenges

Aerospace sealing solutions can face a wide range of harsh environments that can include exposure to extreme temperatures, high pressures, and corrosive chemicals such as de-icing liquids and aviation fuels. There is also the ever-present demand for energy-efficient solutions,  critical requirements related to safety, and compliance with industry standards. 

In addition, aerospace seals must often perform in potentially explosive or flammable environments. There are other constraints in aerospace applications as well, such as the need to minimize weight and promote energy efficiency. And looking to the future, there will also be demand for more environmentally friendly, sustainable solutions.

Busy Engineer’s Lightning Fast Introduction to Labyrinth Compressors


While most people think of labyrinth seals as a type of rotary seal, they also have applications for non-rotating sealing. 

An excellent example of a non-rotary application is to provide a non-contact seal against high pressure while sealing in oil during compression strokes in reciprocating compressors.  The first reciprocating compressor with a labyrinth seal was built in 1935, and this type of reciprocating compressor is known as a labyrinth compressor.  Although the technology has been modernized and improved over time, some things remain the same – including the benefits.
