A duct stringer assembly with a bulkhead. The duct stringer assembly has duct walls providing a duct with a closed cross-section. The duct is adapted to transport fluid. A bulkhead is in the duct, and the bulkhead is adapted to block the flow of fluid along the duct. The bulkhead has a bulkhead body, and a gasket sealing a gap between the bulkhead body and the duct walls.

A tube plug for securely sealing a tube to be plugged. The tube plug has a housing member with a non-cylindrical body and a deformable wall. 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. The non-cylindrical body allow the plug to be inserted into and used to plug a tube that is in a difficult to reach location and whose diameter may not be precisely known.

A fluid routing plug for use with a fluid end section. The fluid end section being one of a plurality of fluid end sections making up a fluid end side of a high pressure pump. The fluid routing plug is installed within a horizontal bore formed in a fluid end section and is configured to route fluid throughout the fluid end section.

A lockout system and method are provided. The lockout system prevents unauthorized and inadvertent operation of any system requiring energy isolation by locking out and tagging out the controls. The lockout system includes a housing and a twist member that allows for selective configuration of the lockout system between a release and retention configuration. In the release configuration, the lockout system is adapted to be selectively positioned within the pipe and removed from the pipe. In the retention configuration, the lockout system is semi-permanently secured to the interior of the pipe via an engagement member. The housing and the twist member each comprise an aperture sized to align and receive a lock wherein once received the twist member is cooperatively secured to the housing via the lock in a locked configuration. In the locked configuration, the lockout system is secured to the pipe and prevents access to the pipe.

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 power end assembly includes a crankshaft section, a crosshead section, and a connector section coupled together by one, two, or more sets of stay rods. The power end may include one or more support plates that are coupled to the crankshaft section and/or crosshead section. The crosshead section includes a plurality of individual crosshead frames. The connector section may include a plurality of individual connector plates or may be a unitary connector plate. The power end is configured to be coupled to a fluid end assembly by coupling the fluid end assembly to the connector plates.

A method and apparatus for conditioning an RV/Marine toilet bowl seal, including providing an apparatus comprising a plug comprising a handle portion; and a solid foam coupled to the handle portion; wherein the handle portion is configured to allow a user to insert or remove the solid foam of the plug from a discharge opening of an RV/Marine toilet bowl; and wherein the solid foam is configured to make contact with at least a portion of the RV/Marine toilet bowl seal; pouring a conditioner into the discharge opening of the RV/Marine toilet bowl; inserting the plug into the discharge opening of the RV/Marine toilet bowl such that the solid foam contacts with at least a portion of the RV/Marine toilet bowl seal; and rotating the plug by about a quarter of a turn.

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.
