A plumbing fitting for selectively allowing the passage of a fluid therethrough includes an elongate body with a first open end and a second open end, with a passageway providing for fluid communication between the first open end and the second open end, where at least one of the first open end and/or the second open end include a connection arrangement for connection with a further plumbing fitting or fixture, and a valve for selectively sealing or unsealing the passageway to allow for a flow of fluid between each of the open ends, with the valve being operable from the first open end or the second open end.

A plug removal tool may include a mount for attaching the plug removal tool to a structure and a plug nut. Additionally, the plug removal tool may include at least one rigid arm extending between the mount and the plug nut. Further, the at least one arm may have at least one translational degree of movement and at least one rotational degree of movement.

A tube plug for securely sealing a tube to be plugged. The tube plug has a housing member with a cylindrical body, an undercut section, and a deformable wall. A ring is rotatably mounted to a post that extends axially from a front end of the housing member and offset from the longitudinal axis so that the ring is eccentric relative to the cylindrical body. An insert member having a threaded shank and a ramped ferrule can be threaded into the body to deform the deformable wall outwardly and into engagement with the tube to be sealed.

A fluid end includes a housing having a bore extending toward a cavity and a wear sleeve positioned within the bore. The fluid end also includes a plunger positioned within a plunger bore extending through the wear sleeve, the plunger reciprocating within the plunger bore. The fluid end further includes a wear sleeve retainer coupled to the housing and positioned to block axial movement of the wear sleeve, the wear sleeve retainer having external threads along a body that engage internal threads formed in the housing. The fluid end also includes an anti-rotation system, coupled to the housing, the anti-rotation system engaging the wear sleeve retainer to block rotation of the wear sleeve retainer in at least one direction. The fluid end further includes a packing nut coupled to the wear sleeve retainer.

A tamper proof plug comprising a circular plug of material having a first side and a second side, with a first plurality of threads on the outer circumference to enable the circular plug to screw into a second plurality of inner circumference threads of a valve outlet that can control the flow of a liquid, wherein the circular plug has a polygon indentation in the middle of the first side of the plug, which is accessible to a tool having a protrusion the fits the size and shape of the polygon indentation, that allows a torque to be applied to the circular plug to screw the circular plug into a valve or unscrew the circular plug from a valve.

The invention relates to a method for producing a gland or a gland blank (3), the method comprising a step of producing a blank (3) having a cylindrical shaft (5) formed on a screw head (4), and a blind hole (7) being formed in the blank (3) from an upper side (11) of the screw head (4) facing away from the shaft (5) in a, in particular further, method step, the blind hole (7) extending toward the shaft (5) and forming at least one first section (13), in particular having a polygonal cross section (Q1), preferably for receiving a screw tool. The blind hole (7) is deepened, thus forming at least one second section (14), which borders the first section (13), in a subsequent method step, the second section (14) forming a preferably at least partially continuous cross section (Q2) which is in particular smaller in size than the first cross section (Q1), the shaft (5) being widened in sections, thus forming an undercut (15) at the crossover between the shaft (5) and the screw head (4), in particular by at least indirectly displacing material from at least the second section (14) of the blind hole (7), in the subsequent method step.

A masking plug is provided for masking a hole in a part during a finishing operation. The masking plug includes an elongated shaft a first end terminating at a terminal surface and a second end. An outer surface of the shaft has external threads adjacent the first end thereof adapted for receipt in the hole. An enlarged body has a first end operatively connected to the shaft and a second operatively connected to a head. The diameter of the body is greater than the diameter of the shaft. The head has a polygonal configuration and is adapted for forming a mating relationship with a tool. The terminal surface of the shaft includes a hollow cavity formed therein which is configured to urge the outer surface of shaft radially outward in response to a pressure buildup in the cavity during the finishing operation so as to maintain the shaft in hole.

A waste pipe fitting assembly includes a tee wye fitting that has an outlet, a first inlet and a second inlet. The outlet is fluidly connectable to a sewer line of a sewer system. The second inlet is fluidly connectable to a drain pipe to place the drain pipe in fluid communication with the sewer line thereby draining water from the drain pipe into the sewer line. A pair of hangers is each of the hangers is coupled to the tee wye fitting and each of the hangers engages a respective support for suspending the tee wye fitting from the supports. Moreover, each of the hangers engages the respective support at an adjustable height to inhibit fluid from collecting in the tee wye fitting.

Example aspects of a nozzle cap for a fire hydrant and a method for manufacturing a nozzle cap to detect leaks in a fluid system are disclosed. The nozzle cap for a fire hydrant can comprise a cap body, the cap body comprising an inner housing and an outer housing, the outer housing defining a cavity; a vibration sensor received within the cavity and configured to detect leaks in a fluid system connected to the fire hydrant; and a metal insert contacting the vibration sensor and the inner housing.

A plug removal tool may include a mount for attaching the plug removal tool to a structure and a plug nut. Additionally, the plug removal tool may include at least one rigid arm extending between the mount and the plug nut. Further, the at least one arm may have at least one translational degree of movement and at least one rotational degree of movement.
