In mechanical engineering, a compression seal fitting, also known as a sealing gland, is intended to seal some type of element (probe, wire, conductor, pipe, tube, fiber-optic cable, etc.) when the element must pass through a pressure or environmental boundary.[1] A compression seal fitting may serve several purposes:
- It restrains the element from moving as a result of a pressure difference.
- It prohibits the leakage of gas or liquid media along the element.
- In some cases, it electrically isolates the element from the mounting device.
A compression seal fitting, unlike an epoxy seal or gasket, uses mechanical components and an axial force to compress a soft sealant inside a body which then creates a seal. An epoxy seal differs in that it is composed of some type of compound which is poured into a mold in an attempt to create a seal.
