About This Solution

Our metal custom design seals are designed and manufactured to precision thanks to additional manufacturing capabilities developed for customer projects and needs. Our metal special design seals are an excellent choice to replace low friction hydraulic seals and standard O-Rings. For example, space and aviation customers often use our metal fitting seals (or metal boss seals) for AS5202 hydraulic fittings per aerospace standards published by SAE. In nuclear applications, you will find special sizes and shapes for seals and parts such as rectangular, oval, triangle, large diameter, etc. - any dimension is possible!

Coating & Plating

While the inner design of a metal seal is key, the outside is just as important. Metal seal platings and coatings have exceptional features in sealing technology. 

  • The additional soft layer is instrumental in improving the leakage rate, used to fill the roughness of the counter flange and enhance the sealing performance.
  • The softer the plating, the more it can improve and cover surface irregularities in the hardware. Generally, a metal seal lies side by side with the high demands placed on the surface quality of the customer’s hardware.
  • Special patented coatings are used to improve the wear resistance. PTFE is typically applied, while plated seals use gold, silver, copper, tin, and nickel as a top layer. For jacketed seals, aluminum lining is used.

Design

Since metal seals are engineered to address critical pressure, temperature and leak rate challenges, they have a greater design flexibility. As a result, our team has designed and manufactured special shapes to accommodate typical dimensional tolerances.
