A seal member and a retaining ring are disposed within the tubular member to form an adjustable seal and grip about the sprinkler body. A releasing member translates to disengage the retaining ring from the sprinkler body; and the escutcheon translates with respect to the tubular member in a sliding surface engagement to define an adjustable deflector-to-rim distance between the rim of the escutcheon and the deflector of the sprinkler.

A tube fitting for connection to a tube includes a main body structure and a tube liner. The main body structure is configured to receive an end of the tube and fluidly connect the tube to another component. The tube liner is positioned at least partially within the main body structure and is configured to extend into the tube. The main body structure and the tube liner are configured such that, when the tube is fully inserted into the tube fitting, the end of the tube is positioned at a predetermined depth within the tube fitting, and the main body structure and the tube liner cooperate together to provide an audible indication to indicate that the tube has been fully inserted into the tube fitting.

A push-to-connect fitting is provided. The push-to-connect fitting includes a connector body, a sealing member, a grab ring, a cartridge, a retainer sleeve, a plurality of latches, and an interference portion. A method of mounting the retainer sleeve over a portion of the connector body is done simultaneously while pushing the plurality of latches located on the retainer sleeve to secure the retainer sleeve to the connector body.

A connector includes a connecting body with a fluid passage at least part way therethrough, and a seal is provided with an outer portion of a fluid tube. A cartridge proximate to the connecting body has a hollow portion therethrough. A grab part has at least one tooth to retain the fluid tube and is between the cartridge and the seal. A demount part within the hollow portion moves the teeth to allow release of the fluid tube. A latch is located on one of the connecting body or a sleeve covering at least part of the cartridge or the connecting body. A mating catch is located on the other of the sleeve or the connecting body, and engagement of the latch with the catch connects the sleeve to the connecting body and helps restrain cartridge movement.

It is described a single line quick connector (10), a system comprising the connector (10) and associated method, for connecting a hydraulic, chemical or water fluid line (20) to a fluid connection interface (2) on a component (1), wherein the connector (10) comprises: an outer housing (11) comprising a tool (12) in one axial end thereof for operation by a tool (3), a flow bore (14) for fluid connection with the fluid connection interface (2) on the component (1), a screw element (13) which is rotationally movable and axially fixed relative the outer housing (11), wherein the screw element (13) extends in a longitudinal direction of the connector (10) and comprises external threads (15) along a part of its axial length and further comprises a termination (16) which is operable by the tool (3), a collet sleeve (17) which is rotationally fixed and axially movable relative the outer housing (11), wherein the collet sleeve (17) further comprises internal threads (18) for cooperation with the external threads (15) on the screw element (13), and wherein the collet sleeve (17) comprises a plurality of collet fingers (19) in an axial end thereof for connection to the fluid connection interface (2) on the component (1), and, a fluid line insert (23) comprising a groove (24) for a coupler (25), wherein the outer housing (11), the screw element (13) and the collet sleeve (17) are arranged such that: a rotation of the screw element (13) in a first direction results in an axial movement of the outer housing (11) relative the collet sleeve (17), and thus the collet fingers (19), in a first axial direction, and a rotation of the screw element (13) in a second direction, opposite of the first rotational direction, results in an axial movement of the outer housing (11) relative the collet sleeve (17), and thus the collet fingers (19), in a second direction, which is opposite to the first axial direction, wherein the outer housing (11) comprises a through-going opening (21) ( ) and the collet sleeve (17) comprises at least one recess (22) between neighboring collet fingers (19), wherein the through-going opening (21) and the at least one recess (22), when connected, are configured to accommodate the fluid line insert (23), and wherein the fluid line insert (23) is connectable to the fluid line (20).
