This AmeriSeal™ high performance metal seal has a temperature range from cryogenic to 2000°F (≈1090°C) at pressures from 1x10^-10 Torr to 100,000 PSI. These seals are typically impervious to corrosion, radiation, or other adverse environmental conditions, provided that the seal material is compatible with the medium. The AmeriSeal™ high performance metal seal is a self-pressure activated design. When the seal is compressed to a predetermined deflection, sealing stresses are generated by the resilient jacket and spring. Unless otherwise engineered, the system pressure is applied to the open side of the seal. AmeriSeal™ high performance metal seals use the compression of the mating hardware contact surfaces and the system pressure or vacuum to provide an effective metal to metal leak proof seal. AmeriSeal™ products utilize high temperature alloys for both jackets and springs. The proper combination of the base materials and surface coatings make it possible to seal almost any fluid at extreme temperatures and pressures without deterioration of the seal over extended periods of time. AmeriSeal™ High Performance Metal Seal Types: Internal pressure External pressure Axial pressure AmeriSeal™ high performance metal seals provide superior performance for most internal, external, and axial applications such as: Low pressure to ultra high vacuum High pressure to 100,000 PSI Low temperature to -423°F (≈-250°C) High temperature to + 2000°F (+1090°C) Because of these capabilities, AmeriSeal™ high performance metal seals are widely used in critical and demanding applications including: Missile and space systems Jet engines, controls, and instruments High temperature aircraft systems Nuclear reactor and waste containment systems Diesel engines Chemical, petro-chemical processing systems Dynamic Applications: AmeriSeal™ high performance seals are ideal metallic seals for limited reciprocating and rotating motion, involving fluids and gasses with system pressures up to 30,000 PSI and cryogenic to high temperatures. The seal design and the unique forming and fabricating process provides a metal seal that maintains contact with the dynamic sealing surfaces. The energizing spring exerts uniform pressure on the jacket and keeps a pre-set load on the seals. This unique design requires moderate sliding force, which can be adjusted to prevent seal deterioration and surface damage in dry or poorly lubricated applications. Design Considerations for Non-Circular Shapes: AmeriSeal™ high performance seals are made in circular and non-circular configurations. The non-circular shapes in most cases require special tooling. There is also a very important relationship between the free height and the corner radii on these seals. Some of the non-circular shapes we are currently producing are square, rectangular, oval, and racetrack.
