Custom Metal Seals

 Applications

..
Applications include pumps, valves, flanges and related devices in aircraft, marine, nuclear and space systems.  Hydrodyne is a major supplier of seals for the Space Shuttle, EELV, and has numerous applications on aircraft engines and satellites.

Metal seals are sensitive to misalignment. Gland surfaces need to be parallel and of the correct dimensions. As misalignment increases, seal performance decreases.

 Seal Material

..
Hydrodyne can design and manufacture from any machinable material. The choice of material is usually made based on compatibility with system fluid and temperatures.

The majority of our seals are static seals; seals that function much like a gasket between two flanges that have little or no relative motion between them. Although we have a variety of standard seals, most of our spacecraft seals are custom designed for a specific application. Custom seal design allows the equipment designer to maximize performance and minimize weight without being constrained by standard seal configurations.

Hydrodyne designed and manufactured metal seals will solve your tough sealing problems.  Metal seals are used where other materials are unacceptable:
