A fluid fitting coupling system which retains two assemblies axially through the use of a flange and lip arrangement and simultaneously retains those assemblies rotationally through either a radial detent or a snap spring are shown in variations. The designs are especially configured for molding so that each might utilize the material properties available and yet be economically manufactured. Further, user features including both visual and potentially audible indications of full assembly are incorporated into the designs and automatically achieved. Shut-off valve designs are shown which are automatically delayed in opening until some axial retention occurs to minimize any blow-off or other undesirable operational events. Swivel features may be incorporated when the application requires.

An apparatus which creates a pre-engineered solvent bond is disclosed which acts to self-optimize the characteristics of the resultant solvent bond. These characteristics can thus be chosen by the part designer with confidence that inherent variations in the assembly process will not unduly impact the resultant bond. The design establishes a specific volume through integral tabs or removable shims within which solvent acts to precisely dissolve material so that the predetermined bond characteristics are automatically created without reliance upon assembler technique.

An apparatus which creates a pre-engineered solvent bond is disclosed which allows the bond characteristics of the resultant solvent bond to be predetermined. These characteristics can thus be chosen by the part designer with confidence that inherent variations in the assembly process will not unduly impact the resultant bond. The design establishes a specific volume through removable shims. Solvent added to this volume acts to dissolve material so that the predetermined bond characteristics are created.

A method and apparatus for preengineering a solvent bond is disclosed. It creates the possibility of preestablishing designs to self-optimize the characteristics of the resultant solvent bond. These characteristics can thus be chosen by the part designer with confidence that inherent variations in the assembly process will not unduly impact the resultant bond. Setting the volume of dissolved material with acting upon it in the dissolved state are included.

A fitting is described for connecting an elastic hose (152) to a system through which a fluid is transmitted. The fitting, based on common barbed fittings, has an angled conical surface (8) which forms a smoothly curved line as the boundary between the surface and the base of the barb. As an integral way to resist rotation of hose (152), which engages hose (152) on its inner surface, one emboidment of the present device is designed with ribs (6) on conical surface (8), while another embodiment maintains such features (designated as 125) on stem (11) of the fitting. The anti-rotation feature is designed in such a way as to minimize any tendency of the anti-rotating feature to diminish the sealing properties of barb (2 or 121). Such a goal naturally is accomplished through physical parameters of the ribbed protrusions, such as height, shape, and length.

A fitting is described for connecting an elastic hose (152) to a system through which a fluid is transmitted. The fitting, based on common barbed fittings, has a non-circular or angled conical surface which forms a smoothly curved line as the boundary between the conically-shaped surface and the base of the barb. This serves as an integral way to resist rotation of hose (152), which engages hose (152) on its inner surface. The anti-rotation feature is designed in such a way as to minimize any tendency of the anti-rotating feature to diminish the sealing properties of the barb.
