Sour gases containing hydrogen sulfide/sulfide (H2S) can have a very adverse effect on elastomers. The elasticity that is not resistant to corrosion becomes hard and brittle, losing elasticity and sealing ability, ultimately leading to sealing failure. JST has developed various sour gas resistant elastomer materials for the oil, natural gas, and petrochemical processing industries with the third-p...

Spring Energized Seals are made up of two components: a polymer-based seal jacket and spring energizer. Spring energized seals are great for use in environments that are too aggressive for other types of seals, as they provide a longer service life, maintain sealing pressure, and offer extreme wear resistance. Spring Energized Seals are popular in the medical device industry for a variety of reaso...

PTFE seal designs were developed to incorporate energizing elements such as O-Rings and metallic springs. These energizers ensure the PTFE seal is always in contact with the sealing surface. JST utilizes three different types springs to internally energize PTFE and other polymer seals, each with its own advantages. Below, we will discuss in details for some of the advantages of cantilever V-spring...
