Abstract

See full text

Disclosed are systems and methods for manufacturing compression collars for reinforcing sealed connections between a length of piping and a plumbing fitting. Specifically, compression collars and related methods of making include extruding a hollow tube having one or more ridges which are then partially removed or trimmed to provide positioning tabs on one end of the compression collar. The compression collars can be cut to the desired length from the extruded hollow tube. In this way, compression collars with features for enhancing the strength and reliability of an interference fit, as well as their ease of use, can be manufactured rapidly with little material waste through modifications to the extrusion process.
