Inventors:

James Donoho - Golden Valley MN
Michael Stoick - Prior Lake MN
Eric Soderstrom - Lauderdale MN
Assignee:

Fluroware, Inc. - Chaska MN
International Classification:

F16L 3500
US Classification:

285 93, 285322, 2853345, 411 14
Abstract:

The torque confirmation fitting is used for coupling one section of tubing to another and includes a fitting body, a fitting nut, and a torque confirmation portion. The fitting body has a nose section that supports an end of one of the sections of tubing. The torque confirmation portion has a collar portion and one or more prongs. The fitting nut is operably joinable to the fitting body and engageable with the torque confirmation portion. To operate, the non-supported end of the tubing is inserted through the torque confirmation portion and the fitting nut. The fitting nut is then joined to the fitting body and in doing so engages the torque confirmation portion. The continued joining of the fitting nut to the fitting body causes the prong of the torque confirmation portion to provide a visual indication that the fitting nut has been sufficiently, tightly joined to the fitting body.

Jun 8, 2000
Appl. No.:

09/589690
Inventors:

James Donoho - Golden Valley MN
Michael Stoick - Prior Lake MN
Eric Soderstrom - Lauderdale MN
Assignee:

Entegris, Inc. - Chaska MN
International Classification:

F16L 3316
US Classification:

2853345, 285110, 2853824
Abstract:

The self-flaring plastic fitting is generally utilized in coupling one section of tubing to another section of tubing. In the present invention, at least one of the sections of tubing has an end portion with a substantially uniform diameter and a groove about its periphery. The fitting itself includes a fitting body and a fitting nut. The fitting body is provided with a tapered nose section while the fitting nut is provided with a groove engaging device. In assembling the fitting, the end of the section of tubing incorporating the groove is place proximate the tapered nose section of the fitting body while the opposite end of the section of tubing is inserted through the fitting nut. The fitting nut is then pushed towards the fitting body where the groove engaging device of the fitting nut engages the groove of the tubing. As the fitting nut is joined with the fitting body, the fitting nut is drawn over the fitting body and, correspondingly, the tubing is drawn against and over the tapered nose section of the fitting body causing the tubing to flare and a seal to be created between the tapered nose section and tubing.

US Patent:

7007391, Mar 7, 2006
Filed:

Oct 18, 2001
Appl. No.:

10/001708
Inventors:

John B. Stoick - Chaska MN, US
Michael A. Stoick - Prior Lake MN, US
Carlos Cadavid - Chanhassen MN, US
Assignee:

Entegris, Inc. - Chaska MN
International Classification:

B23D 21/06
B21F 13/00
US Classification:

30101, 30102
Abstract:

The present invention is a C-shaped plastic tubing cutter having a C-shaped grasping portion and a fixed cutting blade. The grasping portion has an opening for receiving the tubing whereby the width of the opening is measurably smaller than the diameter of the tubing to permit snap engagement of the tubing into the grasping portion upon sufficient force and retention therein. In addition, the inner diameter of the grasping portion can be measurably smaller than the outer diameter of the tubing to promote securement of the tubing within the grasping portion to better facilitate precision cutting. Once engaged, a grasping bias force brings the inner surface of the grasping portion into substantial circumferential contact with the tubing to again promote securement and cutting. The circumferential contact is greater than 50 percent, and generally less than 75 percent, of the tubing circumference.
