Abstract: A gas connector having a tube with corrugations of uniform height and thickness, wherein the corrugations form successively repeating patterns comprising a first segment of non-compressed corrugations and a second segment of axially compressed corrugations. The gas connector eliminates or greatly reduces whistling noises when conveying a gas.

Abstract: A fluid line connector includes a length of tubing having a plurality of corrugations formed therealong between opposing tubing ends. A non-corrugated section is disposed along the length of tubing between the opposing tubing ends such that a portion of the plurality of corrugations extends between the non-corrugated section and each of the opposing tubing ends.

Abstract: A fluid line connector assembly for connecting between two fluid transmission lines or between a transmission line and an appliance or other apparatus, such as a commercial fryer. The assembly includes a length of thin-walled, flexible tubing having helical corrugations extending therealong and opposing non-corrugated and generally cylindrical ends. A braided sheath extends along the exterior of the tubing and is secured at the tubing ends. A base ring is received on a tubing end and includes a first groove. An end fitting, including an interior passage having a second groove, is retained on and cooperable with the tubing end due to a retaining ring captured within a portion of each groove, allowing the end fitting to remain rotatable relative to the tubing. One or more o-rings are compressively positioned between the end fitting and the tubing end to form a fluid-tight seal therebetween.

Abstract: A fluid connector assembly having a flexible austenitic annealed stainless steel 300 series corrugated convoluted tube. At least one end of the tube has a smooth end which is free of convoluted corrugations. The corrugated portion has a hardness range of 150 to 190 points Vickers and the smooth end of the tube has a range of hardness of 275 to 380 points Vickers. A metal compression nut is used in combination with a metal compression ring in a metal fitting the smooth end to couple. The metal fitting is capable of coupling the fluid connector to another connector.

Abstract: A connector assembly for delivering natural gas or propane from a fixed pipe having a shut-off valve to a moveable gas cooking appliance on casters is provided in which a swivel is coupled with a connector which in turn is coupled between the shut-off valve and the gas appliance. The swivel maintains its shape and physical characteristics at least up to 800.degree. F. temperature for at least ten minutes. The swivel has a first body member which has a first and second end. A nut is rotatably coupled to the first end of the first body member. The first body member is rotatable about a fixed first axis with respect to the nut which is coupled to the shut-off valve. The swivel has a second body member having a first and second end. The first end of the second body member is rotatably coupled to the second end of the first body member. The first end of the second body member is rotatable about a second axis which intersects the fixed first axis and is rotatable with respect to the fixed first axis.

Abstract: A fitting made up of a body, a ferrule and a nut. The ferrule has a reduced size cylindrical member that is received in an end of a thin wall tube. The nut and the deformable ferrule are placed over the tube. The nut is wrenched onto the body, which deforms the ferrule at the ferrule groove displacing material of the ferrule inwardly against the tube, bringing the inner surface of the ferrule into sealing engagement with the outer surface of the tube and the inner surface of the tube with the outer reduced cylindrical surface of the body and at both faces of the ferrule. A seal is thus accomplished at the inside surface of the ferrule, forcing the tube into engagement with the reduced size member of the body, thereby reinforcing the tube.
