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) when the element must pass through a pressure or environmental boundary. 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/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 a 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.

Famous quotes containing the words compression, seal and/or fitting:
“Do they [the publishers of Murphy] not understand that if the book is slightly obscure it is because it is a compression and that to compress it further can only make it more obscure?”
—Samuel Beckett (1906–1989)
“To believe in something not yet proved and to underwrite it with our lives: it is the only way we can leave the future open. Man, surrounded by facts, permitting himself no surmise, no intuitive flash, no great hypothesis, no risk, is in a locked cell. Ignorance cannot seal the mind and imagination more surely.”
—Lillian Smith (1897–1966)
“Greater glory in the sun,
An evening chill upon the air,
Bid imagination run
Much on the Great Questioner;
What He can question, what if questioned I
Can with a fitting confidence reply.”
—William Butler Yeats (1865–1939)
