Abstract: A hose fitting includes a fitting body, having an inlet opening, an expansion opening, and an outlet opening. An expansion disc is coupled with the expansion opening and is formed from a deformably resilient material. A portion of the expansion disc expands outwardly from the fitting body, when pressure within the fitting body increases, increasing a volume of the fitting body. The expansion disc contracts, as the pressure within the fitting body reduces. The expansion disc may be removably coupled with the expansion opening using an expansion nut, having an open center portion.

Abstract: A full flow hose fitting includes a fitting end, having an elongated stem with a barbed external surface and a retaining collar, having a barbed internal surface. An internal diameter of the elongated stem approximates an internal diameter of a hose to be attached to the fitting. An inner diameter of the retaining collar is larger than an outer diameter of the elongated stem, defining a retention space to secure an end of the hose when it is disposed between the elongated stem and the retaining collar. The fitting is formed from an assembly process that pushes fittings into the end of the hose rather than using an internal or external crimped ferrule to secure them.

Abstract: A spray nozzle comprising a fitting that includes a connector, an elongate cylindrical portion extending from the connector, and a bore formed longitudinally through the fitting. A flexible tube is disposed in the bore. The nozzle includes a sleeve that includes an inlet opening configured to slideably receive the cylindrical portion. The sleeve includes a converging outlet operative to selectively deform an end portion of the tube when the sleeve is urged longitudinally toward the connector.

Abstract: A swivel connector includes a rotor that is rotatably coupled with a housing stem. In some embodiments a bearing cup is rotatably coupled at one end with an exterior surface of the rotor and anchored at an opposite end with the housing stem. An O-ring seal is positioned between the housing stem and the exterior surface of the rotor. In other embodiments, the bearing cup is rotatably coupled at one end with an exterior surface of the housing stem and anchored at an opposite end with the rotor. In such embodiments an O-ring seal is positioned between the rotor and the exterior surface of the housing stem. A bearing assembly residing within a raceway that is defined by flat surfaces on each of: the rotor, the housing stem, and an interior bearing wall within the bearing cup.

Abstract: A spray gun attachment is provided for fluid supply lines in a fluid handling system. A fluid input portion of a gun body is coupled wife a swivel connector, which includes a rotor that is rotatably coupled with a housing stem. In various embodiments, a bearing cup is rotatably coupled at one end with an exterior surface of the housing stem and anchored at an opposite end with the rotor. An O-ring seal is positioned between the rotor and the exterior surface of the housing stem. A bearing assembly residing within a raceway that is defined by flat surfaces on each of: the rotor, the housing stem, and ah interior bearing wall within the bearing cup.

Abstract: A line guide includes an enclosure end portion and a mounting end portion. Guide balls are rotatably positioned along an open passage of the enclosure end portion. The mounting end portion can include an elongated mounting post and a separate base portion, having an open interior that is shaped to releasably receive the mounting post. The base portion is driven into the ground and the mounting post of the line guide is removably and rotatably disposed within the base portion. A line is pulled through the open passage along a pathway around obstacles adjacent to the line guide. When use of the line is complete, the line guides are removed from the base portions, which are left in the ground for future use.

Abstract: An adjustable sprayer comprising a fitting that includes a connector portion, an elongate cylindrical portion extending from the connector portion, and a bore formed longitudinally through the fitting. The sprayer includes a nozzle having a sleeve portion configured to receive the fitting's cylindrical portion whereby the nozzle is moveable, longitudinally, along the cylindrical portion between first and second spray positions. The nozzle includes a primary outlet and at least one secondary outlet radially spaced from the primary outlet. The cylindrical portion is in fluid communication with only the primary outlet when the nozzle is in the first spray position, and the cylindrical portion is in fluid communication with both the primary and secondary outlets when the nozzle is in the second spray position.

Abstract: A swivel connector of the present technology includes a housing that is rotatably coupled with a rotor, whereby an open fluid pathway extends through the housing and rotor. A rotary union bushing is coaxially, rotatably coupled with an exterior surface of the rotor. A rotor cap is coaxially, rotatably coupled around a length of the rotor; whereby at least a portion of the rotary union bushing is disposed within an interior portion of the rotor cap. A bearing assembly is coupled with the exterior surface of the rotor and at least one of the rotary union bushing or the rotor cap. An O-ring seal may be positioned between the housing and the exterior surface of the rotor to further limit the passage of fluid from the fluid pathway to the interior portion of the rotor cap.

Abstract: A reel assembly is provided to support lengths of fluid delivery line. A support arm is secured at one end with the reel assembly and shaped at the opposite end to engage a support structure. The support arm includes separate arm sections; each having mating end portions that are shaped to be releasably, coaxially securable with one another to resist rotation with respect to one another. The arm sections may be provided in various shapes, including straight and angled, to provide a variable geometry. A pivot joint may be formed within the support arm to allow a portion of the support arm and the reel assembly to pivot with respect to the support structure.
