Utilizing our rapid prototyping department, PCTI was able to quickly meet the application design requirements as provided. We worked with our materials partners to develop a unique non-conductive PTFE blend, and our in-house team, to develop an engineered spring energized seal design. Additionally, we designed advanced, low friction, and high load wear rings for use in this application.
With two weeks of lead time, PCTI was able to meet all of the customer’s design requirements and specs. Our seal design outperformed the in-place sealing solution and achieved qualification certification. The PTFE sealing solution as designed offered a unique solution to the customer's lower wear and longer service life.
