Bellows Seals

Aftermarket

Senior Aerospace Metal Bellows designs and manufactures a variety of bellows dynamic seals.These seals are ideal for high temperature applications where elastomeric seals break down.

These seals are commonly circular but can also be squares, rectangles, ovals or whatever shape will fit with the application.

Common materials of construction are stainless steel or high nickel alloys for higher temperature applications.

Typical applications include engine nacelle seals, firewall seal, fuel drain seal, and engine duct seals.
