Abstract

A gasket assembly and method of manufacture thereof provides a plurality of discrete, interconnected capsule beads spaced from one another. A sealant material is disposed in the capsule beads, such that when the capsule beads are ruptured under an applied clamping force, the gasket material is released from the capsule beads.

Claims (7)

1. A gasket assembly, comprising:

a plurality of discrete, capsules defining enclosed spaces isolated by a wall of said capsules;

a sealant material disposed in said spaces of at least some of said capsules; and

wherein said walls of said capsules are rupturable in response to an applied clamping force to burst said capsules and release said sealant material from said capsules, said capsules being constructed from a single material having the shape of ellipsoids and being interconnected by link segments constructed from a single material forming a string of said capsules, said string being uniformly flexible in all directions to conform to a plurality of peripheral shapes.

2. The gasket assembly of claim 1 wherein said string of capsules forms a closed loop which can be flexed into a plurality of peripheral shapes.

3. The gasket assembly of claim 1 wherein one of said capsules encapsulates one kind of said liquid sealant and another of said capsules encapsulates a different kind of said liquid sealant.
