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 method of manufacturing a clamping ring for a cold-expansion joining system includes providing an extruded pipe part made of a cross-linked polymeric material where, while extruding the pipe part, the inner diameter is formed bigger than the outer diameter of a flexible cross-linked polymeric pipe onto which the clamping ring is positioned before making a pipe connection; providing an injection molded annular part having an inner diameter formed smaller than the inner diameter of the extruded part; and bonding the parts together to form a clamping ring having an inward protruding stop edge at one of its ends. The embodiments further relate to a clamping ring formed from an extruded pipe part made of a cross-linked polymeric material and an injection molded annular part bonded together to form a unitary structure including an inward protruding stop edge at one of its ends.

An adapter for connecting a separated-outlet fluid cartridge to a single-inlet static mixer includes a lock mechanism and a lock release mechanism. The adapter includes a connection portion that engages the mixer. The lock mechanism has at least one snap arm that lockingly engages the cartridge in a snap fit manner so as to secure the adapter to the cartridge in fluid communication. When in the locked position, separate fluids are evacuated from the cartridge into the mixer where they are mixed prior to dispensing. The lock release mechanism quickly and easily unlocks the at least one snap arm from the cartridge for allowing a user to separate the adapter from the cartridge. The adapter sealing engages with both the mixer and the cartridge so that fluid flowing from the cartridge to the mixer does not leak.

A repair system for repairing a polyolefin pipe containing a transitional film applied over and bonded to the pipe and a reinforcement system, applied over the transitional film. The transitional film has a first side adapted to bond to polyolefins and the reinforcement system contains a fiber-reinforced polyurethane system bonded to the second side of the transitional film. A system two polyolefin tubular members joined end-to-end containing two tubular members arranged such that their respective ends are adjacent, thereby defining a circumferential joint, a transitional film applied and bonded to the circumferential joint and at least a portion of the two tubular members, and a reinforcement system applied over the transitional film. The transitional film has a first side adapted to bond to polyolefins and the reinforcement system contains a fiber-reinforced polyurethane or a fiber-reinforced epoxy system bonded to the second side of the transitional film.

The present disclosure relates to a male connector holder for an automatic chemical supply apparatus, in which as an upper stage that is independently movable in a front-rear direction is provided on a lower stage that is moved in the front-rear direction by a transfer unit, and even when a male connector having a stretched neck region is seated on the holder, the automatic chemical supply apparatus may be smoothly and normally operated.

The present disclosure relates to a male connector holder for an automatic chemical supply apparatus in which, before a chemical is supplied, a neck region of a male connector is pressed through a clamping holder and a support pad to perform alignment on the male connector so that the male connector may be accurately fastened to a female connector.
