Rapid response on Sikorsky Black Hawk components

PPE designed, manufactured and tested a selection of seals for the iconic Sikorsky UH-60 Black Hawk helicopter, providing a more cost-effective and timely alternative.


Sikorsky Aircraft Corporation was faced with an expensive redesign of precision machined components for its UH-60 Black Hawk military helicopters, with units operating in the armed forces of 25 countries around the world. An extended consultancy period could lead to avoidable downtime of the fleet, as well as substantial costs.


PPE engineers were able to provide a component redesign service as part of their in-house rapid response service. Through this service, PPE produced a non-standard O-ring moulding tool and sample DTD specification FKM seals, manufactured in a fraction of the time it would have taken to source the same seals in the United States.

The first custom designed component samples were received by Sikorsky Aircraft Corporation within just four days – including a weekend – as part of a service which was much more cost-effective and timely.


The three seals developed by PPE would deliver a cost saving of $30,000 on component redesign. Furthermore, subsequent testing of the seals demonstrated flawless operational performance in the field.
