Typical applications include pressure vessels, autoclaves, holding tanks, pipelines, furnaces, or anywhere wires or sensors need to pass from inside to outside a vessel or wall where the pressure differentials or hazardous environments cause concern.
When sealing on multiple elements, gland designs also include a seat and an anti-rotation pin to prevent wires or conductors from twisting and shearing.
Since then, compression seal fittings have evolved to include multiple variations for different applications.
Some applications include: Single-element compression seal fittings are used to seal a single element such as a temperature probe, tubewell, pipe, etc.
Multiple-element compression seal fittings are used when multiple elements of the same or different diameters such as metal tubing, ceramic or rigid plastic tube or pipe, temperature probe, a tubewell, low voltage instrumentation wire, or a power supply feedthrough.
