gland installation
- September 15, 2016
Today we’ll continue our look at spring energized seals by discussing gland designs and installation.
We begin with two-piece glands. Spring energized PTFE seals are rigid when compared to elastomer seals such as O-rings, and can be damaged if stretched or compressed beyond their material limitations.
That’s why we recommend using a two-piece, split gland design whenever possible. This allows easy installation or removal of the spring energized PTFE seal without the need for additional tools, and will greatly reduce the risk of damage to the seal.
Lead-in chamfers that are blended and very smooth are needed to prevent seal damage during installation. You can find full surface finish recommendations by downloading our complete spring-energized seal guide.
