144-point seal engineering process

We thoroughly analyze every operational variable to ensure maximum reliability and performance in even the harshest operating environments. Our 144-point process includes:


Engineering the right solution for a specific application starts with choosing the proper materials. We utilize a range of materials so that we can ensure every seal is optimized for whatever operating environment it will be exposed to.

Validation testing

Because there is no governing body that specifies seal validation requirements, you need a seal supplier you can trust to use only the best materials and produce the most reliable seals for your application. Our testing capabilities include compound immersion testing for rubber validation and a wide variety of customer-specific, functional rig tests on actual seals.
