Provided is a connector assembly for joining a male member and a female connector member together to secure fluid communication in a fluid line system. The connector assembly includes a cover that is pivotally attached to the housing to conceal verification indicia when the male member is not attached to the housing. The cover configured to pivot relative to the housing to reveal the indicia once the male member is attached to the housing to allow a user or scanning device to view the indicia to verify a secure attachment of the connector assembly.

A connector and process for coupling a tube and the resulting assembly is disclosed. A receptacle includes a pilot in a mounting position. The pilot including an indicator piece and guide members each located in a respective channel on the receptacle and slidable within the channels from the mounting position to a final position. A retention clip having legs is urged into a spread condition during a transition between the mounting position and the final position wherein in the final position the legs of the retention clip retract to a relaxed condition, the indicator piece becomes visible on the receptacle and the first and second guide members latch the pilot to the receptacle.

A polymeric riser cap member includes a central tubular section defining a generally cylindrical bore for receiving a sprinkler riser, the central tubular section having open top and bottom ends, and an annular skirt coaxial with the central tubular section and having an inner diameter larger than an inner diameter of the central tubular section. The annular skirt has an inner surface having internal threads threadably connectable with the externally threaded surface of a tubular riser adapter member of a tubular coupler. The bottom end of the central tubular section has an annular projection disposed opposite and spaced from a portion of the annular skirt. The riser cap member includes an annular recess adapted to receive a seal located in a wall extending laterally between the annular skirt and the annular projection.

A system for quick connection between a female end piece provided with a U-shaped locking clip and a male end piece fitted therein, the wall of the female end piece having opposite slits through which the arms of the U-shaped locking clip protrude into the passage of the end piece and the wall of the male end piece having an outer groove lockably receiving the clip arms in a final fitted state of the male piece in the female piece, locked by the clip. Also included is a part forming a removable prestressing element for the clip with housing sites engaging the two free sections in a first resting configuration, and in at least a second prestressed configuration in which the arms are more separated than in the resting configuration but less than during the passage of the maximum outer section of the male end piece.

A method of borehole pipe installation begins with unfinished stick pipes brought to the installation site and then machined or cut to form male and female ends. The pipe ends are then locked together to form a flush joint. The lock can be provided via a groove cut into one of the ends for receipt of a lock gasket, which secures and seals the joint when the pipes are pushed together, and prevents the pipes from being pulled apart. Alternatively, to the groove and lock gasket, the ends can be glued and screwed together, with the screws allowing the joined pipes to be pulled through the borehole before the glue is dry. The pipe joint has flush exterior and interior surfaces to minimize borehole clearance and maximize fluid flow through the pipe assembly.

A pipe connection may include a female component with a sealing portion, a stoppage flare, and a first locking section and a male component with a nozzle configured for sealingly engaging the sealing portion, a stopping cone for abutting the stoppage flare, and a second locking section.

A double wedge locking mechanism provides an attachment mechanism to a liner system for fluid distribution network.

A connection assembly is used to connect a first body to a second body. The first body includes a bore that is coaxial with a first axis, and a retainer opening that extends coaxially with a second axis. The second axis is perpendicular to the first axis and offset relative to the first axis. In addition, a portion of the retainer opening intersects the bore. The second body includes an insertion portion that is disposed in the bore, a fluid passage that extends through the insertion portion and communicates with the bore, and an outer surface of the second body has a channel. The connection assembly employs an elastic retaining pin that retains the insertion portion within the bore. The retaining pin is disposed in the retainer opening such that a portion of the retaining pin resides in the channel, and the retaining pin is self-aligning and self-retaining.

A connector includes: a tube body formed in a tubular shape having a first opening and a second opening at both ends thereof, a first opening side of the tube body being connectable to an end of a first pipe, a second opening side of the tube body being connectable to an end of a second pipe, the tube body allowing a fluid to flow therethrough between the first opening and the second opening; a temperature detection element embedded in a tubular part of the tube body and configured to detect a temperature of the fluid flowing through the tube body; and a terminal electrically connected to the temperature detection element and exposed to outside of the tube body.
