A fluid connection system for a pump or other fluid handling device includes adapters for connecting fluid lines and fittings of different diameters to a fluid port. The system includes a sliding quick disconnect element with an adapter inserting internally of the quick disconnect element into a bore of the port. The adapter includes a cylindrical body with an outer annular groove that receives an O-ring for sealing against the bore of the port. The adapter body includes a first portion having a first inner diameter and a second portion having a second portion having a second diameter for receiving the fitting from the fluid line. The quick disconnect element receives the adapter internally of the quick disconnect to retain the adapter. The adapters having different diameter internal cavities and may be interchanged for using the same port for fluid lines of different sizes and diameters.

A quick connector comprising a connector body having a collar defining an opening, a verification indicia fixed to the collar, and a sliding locker including a base, and a lock arm. The base can include an armature integrally and immovably joined with it, having a wing extending along and spaced from an outer surface of the collar. The lock arm and wing are all simultaneously moveable in unison when the locker transitions from an unlocked mode, where the base protrudes from the transverse opening and supports the wing to obstruct the verification indicia, thereby inhibiting reading and/or scanning of the verification indicia, to a locked mode, where the base is inserted farther into the opening and supports the wing to allow reading and/or scanning of the first verification indicia to confirm proper installation of the quick connector. A related method of use is provided.

A metallic fitting assembly employs a clip-to-body attachment for locking a tube end of a fluid system component to the fitting assembly. The fitting assembly includes a fitting body defining a fluid flow path between a first end and a second end opposite from the first end. The first end receives a tube end of a first fluid system component, and the fitting body defines a clip slot adjacent to the first end, and a material of the fitting body includes metal; and a clip wherein a material of the clip includes metal. When the tube end is inserted through the first end of the fitting body, the clip is inserted through the clip slot and around the tube end to engage the tube end in a connected state in which the tube end is locked within the fitting body. The fitting body includes a main body and a ring end that define the clip slot between the main body and the ring end, the main body and the ring end being attached to each other by a bridge. For freeze resistance, the ring end minimizes distortion of the ring end to 0.010 (0.25 mm) or less at a tensile load of 500 lbf (2200 Newtons). A ratio of a cross-sectional area of the ring end to an inner diameter of the fitting body may be from 21% to 73%. The bridge may have a width within a range of 20% to 70% of an outer diameter of the fitting body.

A valve device (20) includes male and female housings (22, 24) that together define a fluid through-passage (28). The male and female housings have, respectively, exterior and interior annular channels (22a, 24a). The male housing is receivable into the female housing such that the exterior and interior annular channels together define a toroidal tube. First and second valve elements (30, 32) are disposed, respectively, in the male and female housings. Ball locks (36) are receivable into the toroidal tube and axially lock the male and female housings together. A lock (40) engageable when the first and second valve elements are in functional alignment and which when engaged rotationally locks the male and female housings.

A locking device for pipes, comprising an inner and an outer pipe provided with adjoining and corresponding circumferential grooves for releasable locking engagement via a locking ring fitted in the grooves and thus releasable locking between the inner and the outer pipe by alteration of the radius of the locking ring, wherein the locking ring has an open section or circle sector along the periphery thereof and is provided, at least at the two radial ends thereof, interrupted by the open section, with two respective guide members comprising respective guide surfaces that are slanted relative to the periphery, and wherein a first one of the guide members is provided with an end stop and a second one of the guide members is provided with a control mechanism protruding through an oblong opening provided through the outer pipe along a portion of its radial groove, wherein the radial displacement of the control mechanism along the oblong opening increases the open section or circle sector of the locking ring while simultaneously forcing the radius of the locking ring to increase for release of the locking engagement owing to the slanted guide surfaces.

A securing device is disclosed having a flange mountable on a suction-providing source, and having pipe members that detachably receive a corrugated pipe such as a drain tile. A major or outer pipe is concentrically and integrally joined to, and extends perpendicularly from the flange. The outer pipe includes a rod receiving slot extending circumferentially and radially through a predetermined portion of the outer pipe. A minor or inner pipe is concentrically and integrally joined to, and extends perpendicularly from the flange such that the inner pipe is concentrically disposed inside the outer pipe. A latch is mounted on the outer pipe and is and is movable between a latched position and a fully unlatched position. A securing rod is pivotally connected to the outer pipe and is operatively associated with the latch subassembly so as to be movable from a secured position to a released position. When the latch subassembly is in the fully unlatched position, the rod is in the released position, and when the latch subassembly is in the latched position, the rod is in the secured position to detachably secure the position of a drain tile upon the inner pipe.

A quick connector is provided. The quick connector is configured to be coupled to a locking ring provided around an outer peripheral surface of a tube, through which fluid flows in or out. The quick connector includes a main body, which accommodates the tube therein and includes locking members, formed to be locked by the locking ring and being bent toward the locking ring, and a mounting guide coupled to the outer peripheral surface of the main body and accommodating the locking members therein. The mounting guide is configured to slide along the longitudinal axis of the main body so as to enable the locking members to be locked around the locking ring or to be released from the locked state.
