SEALING COMPRESSION FERRULE FOR PLUMBING CONNECTION FITTING

Title:

SEALING COMPRESSION FERRULE FOR PLUMBING CONNECTION FITTING

Document Type and Number:

WIPO Patent Application WO2003089825

Kind Code:

A3

Abstract:

A compression connector for sealingly connecting a fluid line(12) to a plumbing fitting (14), valve or connector. The connector assembly sealingly retains the tubing within the device to direct flow therethrough The plumbing fitting includes a seat (26) for matingly receiving the tubing in fluid communication with the interior passageways of the fitting. With the tubing seated in the fitting, a compression ferrule (46) and a compression nut (30) are coaxially mounted to the tubing. The compression ferrule includes wedge-like edges at both the leading and trailing ends thereof. The compression nut has an angled shoulder (44) configured to engage the trailing edge of the ferrule. As the nut is rotated onto the fitting, the angled shoulder deflects the trailing edge of the ferrule radially inwardly into engagement with the tubing. Similarly, the leading edge of the ferrule is deflected radially inwardly into engagement with the tubing. The dual deflection edges create a sealing connection of the tubing within the fitting.
