20080197629 | Connecting Arrangement For Refrigerant Lines - A connecting assembly for coolant lines, in particular for motor vehicle air conditioning systems which are operated with CO | 08-21-2008 |
20130127160 | Coupling Having Gasket Pocket of Varying Depth - A mechanical coupling for joining pipe elements has segments joined end to end, each segment having a pocket of varying depth for receiving a ring gasket. The varying depth of the pocket is used to control the distortion of the ring gasket between a round shape and a non-round shape when the segments are arranged in spaced apart relation around the ring gasket, the spacing between the segments being sufficient to permit insertion of the pipe elements without disassembly of the coupling. | 05-23-2013 |
20140203552 | RESTRAINING SYSTEMS FOR BELLED PIPE - A restraining system for connecting a belled end of a female pipe to a spigot end of a male pipe is disclosed. The system includes a ring-shaped casing having circumferential grooves separated by an abutment surface. One or more restraining rings or members are disposed in the grooves so as to contact both the casing and the outer surfaces of the male and female pipes. The one or more restraining rings restrain the pipes from moving away from each other when the system is pressurized. | 07-24-2014 |
20150308595 | CONNECTOR ASSEMBLY FOR CONNECTING PIPES - Provided is a connector assembly for connecting pipes comprising: a connector formed with a hollow into which a pipe is inserted, a large diameter portion being included on at least one side of both end portions of the hollow, the large diameter portion being formed to have a relatively large inner diameter and having a housing space inside; a ring-shaped sealing member provided in the housing space; and a grip member provided adjacent to the sealing member in the housing space, wherein the grip member has a body portion formed to contact along an inner circumferential surface of the large diameter portion, and a pair of sharp portions that is formed in shapes corresponding to each other to be bent from both sides of the body portion, and is formed so as to partially bite into the outer circumferential surface of the pipe inserted into the hollow by crimping the outer circumferential surface of the large diameter portion, and under the condition of crimping the outer circumferential surface of the large diameter, bending strength of the body portion is set to be relatively lower than the sharp portions. | 10-29-2015 |
20150323112 | Push-Fit Pipe Couplings - Push-fit pipe coupling assembly includes a demount tool and a pipe coupling. Each demount tool is in the form of a part ring having an internal thread and a pressing portion. Each coupling includes a body having an exterior thread and a demount collar. In use, the thread of demount tool engages with the exterior thread. As the demount tool moves, an abutting shoulder of the pressing portion comes into contact with the engaging portion of demount collar. This forces an angled contact surface to press on the teeth of a grab ring, preventing the teeth from engaging with a pipe inserted into the coupling, allowing the relative position of pipe and coupling to be adjusted. | 11-12-2015 |
20150362098 | Refrigeration Line Set Fitting and Method of Using the Same to Join Refrigeration Lines to Each Other - A crimp fitting comprises a metal tube wall that forms both a cylindrical tube portion and an adjacent annular O-ring channel portion. The tube wall has a first wall thickness along the cylindrical tube portion and a second wall thickness along at least part of the O-ring channel portion. The second wall thickness is less than the first wall thickness. The cylindrical tube portion and O-ring channel are configured and adapted to encircle a cylindrical end portion of a tube when such end portion of the tube is inserted into the fitting. | 12-17-2015 |
