Factors Influencing PTFE Seal Behavior: The PV Limit - Part 2 in a 3 Part Series

Posted On June 17, 2016

The performance of a dynamic PTFE seal depends greatly on the pressure and shaft velocity involved. In reality, a seal is in contact with only a small area of rotating shaft, which means that the dynamic forces and energy are going to be concentrated there. Much of the energy that comes from the shaft is going to be dissipated in two forms: wear and frictional heat, both of which can reduce the useful life of a seal. An increase in the force that holds the seal lip against the shaft or an increase in the speed of the shaft makes the effects of wear and heat even worse.

Factors Influencing PTFE Seal Behavior: The Mating Surface - Part 1 in a 3 Part Series

Posted On June 11, 2016

The useful life of a PTFE seal is heavily influenced by the surface over which the seal slides or rotates. This includes both the material choice, surface finish, and hardness of the mating surface. In this article, we will look at how the mating surface influences the life and behavior of a PTFE seal and how to account for that effect during the design process.

Cheat Sheet on Surface Finishes and PTFE Spring-Energized Seals

Posted On April 01, 2016


PTFE Spring-Energized Seal Design

When designing a component that includes a spring-energized PTFE seal, it’s not enough just to specify all the seal parameters; another key part of the design is the surface finish of the mating surface.  In this article, we are going to review what surface finish is, discuss the effects of surface finish on seal life, and then go over recommended surface finishes for spring-energized PTFE seals.
