US Patent 9371945 Corrugated tube connector

A connector for a length of corrugated tubing. The connector includes a fitting including a passage therethrough, a clamping surface, a seal, and a nut operably connected to the fitting. The tubing is in fluid communication with the passage through the fitting. Axial movement of the nut towards the clamping surface-urges the tubing against the seal wherein the tubing is thereby sealingly restrained to the fitting and a clamping surface is formed capable of causing an end portion of the corrugated tube to form a flare by the end portion of the corrugated tube being compressed against the clamping surface and the seal and sealed thereagainst by the action of the nut.
