Metal Seals » Spring-Energized

Metal seals for the most extreme applications with a flexible design. Spring-Energized metal seals utilize an combination of a helical spring surrounded by one or more layers of softer metal. The softer metal jacket flows into the flange groove finish so that a highly effective seal can be achieved. This type of seal was developed specifically for solving high risk nuclear flange applications. In addition to making a great seal for nearly every high temperature and high pressure application in every industry, the seal also can be manufactured in nearly any geometry from round, square, triangular, to oblong.

FEATURES
  • Tightest metal sealing product available; thick outer jacket or plating with helically wound spring

  • Temperatures from cyrogenic to over 2500F
  • Pressures up to 100,000 psi
  • For internal, external, and axial pressure applications
 
BENEFITS
  • Handles rougher surfaces than other metal seals
  • Variety of jacketed materials engineered with a light to heavy load internal spring to optimize performance
  • Available in many standard cross sections and custom sizes with low tooling costs
  • Ultra-high vacuum sealing levels
