Abstract
A sealing device and method for sealing a length of tubing with a fitting, where the sealing device includes at least one sealing surface formed with a plurality of ridges. The sealing device is particularly useful for sealing at least an end corrugation of tubing in a fitting used in gas and liquid piping systems. The fitting is sized to maintain a generally circular shape of the end corrugation after the corrugation is collapsed between the ridged sealing surface and another sealing surface. In particular, an inner diameter of one or more components of the fitting can be sized such that the corrugated tubing will have a circular profile to provide an optimal seal.
