History and Development
Soft sealant technology for compression seal fittings was developed in the 1950s by Conax Technologies. Since then, compression seal fittings have evolved to include multiple variations for different applications. Some applications include:
Single Element Sealing
Single element compression seal fittings are used to seal a single element such as a temperature probe, tubewell, pipe, etc.
- Packing Gland (PG) Series- For sealing on anything from fragile tubes and soft cables to solid probes or instruments
- Midlock (MK) Series- Best used for sealing on metal elements and/or high vibration environments.
- Electrode (EG) Series- Fully isolating for electrical power or instrument isolation to 8000 V. Teflon insulation and sealant material used for high performance and chemical resistance.
- Split (PGS) Series- seals cables and leads when larger probes or connectors are attached.
Multiple Element Sealing
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.
- Transducer (TG) Series-For bare wire sealing where elements remain fully electrically isolated throughout the fitting
- Multi-hole Ceramic (MHC) Series-Non-isolating fitting for multiple elements up to 0.125 in (3.175 mm) diameter.
- Multi-hole Metal (MHM) Series-A flexible design for special hole patterns, irregular shapes and mixtures of element sizes.
- Split (PGS/SPG/DSPG) Series-For sealing elements that can pass through gland body but not the internal components.
- Sensor Wire Seal (BSWS) Series-Used for sealing on sensor leads in low temperature and pressure applications. Ideal for embedded bearing temperature sensors, vibrations sensors and proximity probes.

Famous quotes containing the words history and/or development:
“What we call National-Socialism is the poisonous perversion of ideas which have a long history in German intellectual life.”
—Thomas Mann (1875–1955)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
