Some fluid coupling devices described herein are configured as non-spill fluid couplings. In addition, some embodiments described in this document relate to fluid coupling devices and fluid coupling systems that are constructed in a compact configuration.

A hose repair system including a first clamping member and a second clamping member, each clamping member including an interior surface with a concave curve along the width and a pair of longitudinal grooves formed at the intersection of the first and second clamping members. Each longitudinal groove extends from end to end of each clamping member. The system also includes at least one fastener for clamping the first and second clamping members together.

A fuel quick connector body according to various aspects of the present disclosure includes a wall. The wall extends along a longitudinal axis between a first end and a second end. The wall defines a passage between the first end and the second end. The body includes a polymer. The polymer includes polyphenylene sulfide in an amount greater than or equal to about 70 weight percent. The polymer may have a flexural modulus of less than or equal to about 4 GPa. The polymer may have a notched ISO impact strength of greater than or equal to about 25 kJ/m.sup.2. The polymer may have an elongation at break of greater than or equal to about 15%. In various aspects, the present disclosure provides a fuel quick connector including the fuel quick connector body, a retainer component, and an O-ring.

A hose connector for joining flexible hoses is comprised of a tubular pipe body with at least one insertion portions made of a shape memory alloy (SMA) or other shape memory material that has a memorized shape. The insertion portion is located on at least on one end of the tubular pipe body and has an outer diameter smaller than an interior diameter of the flexible hose in a martensite state. The insertion portion is inserted into the interior diameter of the flexible hose and the memorized shape is recovered with the application of heat, wherein the outer diameter of the insertion portion becomes larger than the outer diameter of the flexible hose sealing the outer diameter of the insertion portion against the interior diameter of the flexible hose.

A manufacturing method for manufacturing a pipe joint including a circular tube-shaped housing and an elastically deformable circular tube-shaped seal member provided at an inner peripheral side of the housing. The pipe joint manufacturing method includes a process of placing the seal member inside a mold in a state in which the seal member is fitted to an outer periphery of a retaining pin, and a process of causing a molten resin to flow into the mold so as to mold the housing in a state in which the seal member is cooled through the retaining pin.

A hose connector is formed at the end of a rigid pipe body used to connect the pipe body to a flexible polymeric hose. The hose connector includes a frustoconical front end extending outward from a tip to a radially enlarged first ring portion that terminates at a circumferential first step. A radially reduced second ring portion extends from the first step backwards at a constant diameter to a circumferential rear edge. A circumferential second step extends from the second ring portion rear edge backwards in a decreasing circumferential diameter to a mid-section of the pipe body. A flexible hose is adapted to be inserted by pressure over the pipe body at the tip end until it passes beyond the second step to at least the mid-section of the pipe body.

In the case of a connector coupling, a rib structure (4) is configured on a hose nipple (3), which rib structure (4) has at least one first rib (5), the at least one first rib (5) extending continuously from a rib start (6) as far as a rib end (7) which is spaced apart axially from said rib start (6), and winding around the hose nipple (3) over a circumferential section of more than 180°, preferably more than 270°, particularly preferably over more than 360° or at least once.
