Abstract
A seal features a first curved region generally concave in a direction of concavity, and a second curved region generally concave in the direction of the concavity of the first curved region. The second curved region is oriented within the direction of concavity of the first curved region. A first bend connects the first curved region to the second curved region, and a second bend connects the first curved region to the second curved region.
Claims14
A C-shaped seal comprising:
- a first curved region having a first radius of curvature, an inner concave surface, and a cross-section generally concave in a first defined direction of concavity;
- a second curved region having a second radius of curvature which is smaller than the first radius of curvature, an outer convex surface which abuts the inner concave surface of said first curved region and a cross-section generally concave in substantially the first direction of concavity of the first curved region;
- a first acute bend connecting said first curved region to said second curved region;
- and
- a second acute bend connecting said first curved region to said second curved region, wherein the seal is formed from seamless tubing.
