In the case of a hose connector assembly (1) it is provided for a retaining plate (15) to be used for axially fixing at least two hoses (6, 7, 8) in corresponding hose receptacles (3, 4, 5). The hoses (6, 7, 8) are insertable into respective recesses (16, 17, 18) of the retaining plate (15) by way of a lateral insertion movement (19), and the hoses (6, 7, 8) engage behind the recesses (16, 17, 18).

A first projection is formed on the outer periphery of a bulb part, a second projection is formed on the socket rear end of the bulb part, a tapered part is formed with a decreasing diameter from the inner periphery of a heel part to the inner periphery of the second projection, and a third projection is formed on the tapered part. A first dimension B from the first projection to the third projection in an inclination direction opposite to an inclination direction G of the tapered part is smaller than a second dimension C from the first projection to the second projection in a radial direction A.

A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides an internally restrained pipe joint including a bell with a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of toothed, rigid restraining segments is at least partially embedded in the gasket.

A pipe sealing gasket is shown which is designed to be received within a raceway provided within a socket end of a female bell plastic pipe end which is assembled with a mating male pipe end to form a plastic pipe joint. The raceway in the female bell plastic pipe end is preformed during manufacture and the gasket is installed thereafter. The gasket has a rubber body portion which is reinforced by a hard plastic band formed as a series of integral, spaced wedges which are interconnected by a flexible ribbon. The gasket is flexible enough to be flexed and placed in the pipe raceway and yet the hard plastic band acts to prevent extrusion of the gasket during a variety of pressure conditions as well as preventing displacement during field assembly.

Disclosed herein is a packing nut lock for a fluid end assembly of a reciprocating pump. The fluid end assembly includes a fluid end block component, a set screw which may have a pointed end, and a packing nut. The set screw engages or interlocks between the a first and second thread of a threaded bore to prevent displacement of the packing nut from the threaded bore.

A pipe-fitting includes a coupling and a flexible pipe-restraint gasket. The coupling includes a bell that defines a pipe insertion mouth at an end of the coupling and an inner recess. The flexible pipe-restraint gasket assembly is disposed within the inner recess and includes an annular body, a plurality of discrete gripping members and at least one extension portion. The plurality of gripping members are disposed around an outer periphery of the body. The at least one extension portion extends from the body and is disposed between a pair of the plurality of gripping members. The at least one extension portion defines a pocket.

A tool for confirming the connection status of a fluid line to a quick-connect fluid coupling assembly includes a hub portion configured to interface with an outer portion of the fluid line, a finger coupled to the hub portion, a handle portion, a spring portion coupled to the hub portion and to the handle portion, and an indicating means. When the tool is placed in contact with the fluid line, a biasing force is applied to the tool in an axial direction, and a torque is applied to the handle portion to rotate the handle portion by a predetermined amount about the longitudinal axis of the fluid line, the finger cooperates with the retaining clip to produce a reaction torque to activate the indicating means when the fluid line is properly connected to the fluid coupling assembly.

A method for inhibiting separation of joined pipes including providing within a pipe bell a gasket including rigid segments, each segment having bell teeth configured for engaging the bell and a spigot tooth configured for engaging a pipe spigot seated in the bell. Upon pressurization and over-pressurization of the joint, resulting axial forces exerted on the joint, which can cause pipes to separate, are countered by wedging the segments between the bell and the spigot and rotating each segment so that the thrust forces are directed radially. To prevent radially-directed thrust forces from damaging the joint through over-rotation of the segments, the bell teeth and the spigot tooth are adapted and arranged to maintain the thrust forces load path carried by each segment within a desired angular range relative to the spigot by transferring the load path between adjacent bell teeth whereby the effective length of each segment is increased.
