A pipe fitting having a base configured to engage with a pipe, the base having a mounting seat configured to engage directly with the pipe, a base ring configured to engage with the mounting seat, and a base flange configured to engage with the base ring, a top hat configured to engage with the base, the top hat having a top cap, a top hat ring configured to engage with the top cap, and a top hat flange configured to engage with the top hat ring, wherein the top hat flange is further configured to engage with the base flange to form a fitting cavity. A pipe flow controller may be in fluid communication with the internal pipe volume through a threaded nipple, while also being securely housed within the fitting cavity, thus protecting the pipe flow controller from corrosion, impacts and other forms of damage to prevent leakage.

A spud connection to a cylindrical tank wall includes a spud body welded to a cylindrical tank wall. In at least some embodiments, the spud body has an arcuate and concave first end surface, and a planar second end surface spaced apart from the first end surface. A weld joint between the first end surface of the spud body and an outer surface of the cylindrical tank wall surrounds an aperture that extends through the cylindrical tank wall, so that a leak-free fluid connection to an interior volume of the tank can be achieved.

An apparatus for sealing a hole or a shape in a surface may be disclosed. According to an exemplary embodiment, a soft material may be provided containing an interior hole, an exterior surface, a top lip, and an outer area. In an exemplary embodiment, a bottom lip may be further incorporated. In another exemplary embodiment, a rough surface may be imprinted onto the pipe seal apparatus. The rough surface may be imprinted into the interior portion of the body and the exterior portion of the body and the top lip, or both. An adhesive pipe sealant may be used along the rough surface. The rough surface may have a higher overall surface area for the adhesive to bond to, creating a stronger bond and preventing delamination.

Apparatus and installation methods for sampling ports are disclosed. Sampling ports include a port housing and a lid assembly. The lid assembly is configured to sealably close against the port housing. Additionally, the lid assembly can be secured, such as with a lock, to the port housing. In one aspect, the port housing includes a sample mount arrangement configured to receive a sampling assembly. The sample mount arrangement defines a sampling channel and the port housing defines a sampling opening and a first securing mount. The lid assembly includes a latch arrangement and defines a second securing mount.

A coolant connecting piece (100) for conducting coolant between a first housing (201, 503) and a second housing (203, 507). The coolant connecting piece (100) comprises a cylindrical main body (101) with a coolant channel formed on an inner side of the main body (101), and a protective ring (103) with a drip edge (117), wherein a cross-section of the protective ring (103) is greater than a cross-section of the main body (101), and wherein the drip edge (117) is configured to let condensate running off on an outer side of the main body (101), opposite the inner side, drip off into a predetermined region (213).

A clothes dryer exhaust vent (dryer vent) and the method of installation in a residential or commercial building exterior foundation wall, during construction of a building, to save the expense and costs of a clothes dryer exhaust vent installation after a building has been constructed, to reduce repair and additional construction costs. The dryer vent has a rigid wall mounting plate (plastic or metal) that is mounted in the construction block array of an exterior building foundation wall while the wall is under construction. The clothes dryer exhaust vent includes a clothes dryer exhaust vent tube connected through the rigid, wall mounting plate (manually removable), an exterior (outdoors) hemispherical-shaped clothes dryer vent open end cover assembly, manually removable for cleaning and removing lint, said cover assembly including a clothes dryer exhaust vent flapper valve.

A single piece structural connector is provided that includes a single machined aluminum piece having first and second circular ends including a plurality of bolt holes and a center hole. The connector also includes an alignment dowel positioned on the center hole. The alignment dowel is configured to tightly fit into a center hole of a pipe plate.

A pipe trim assembly for trimming a pipe extending through a wall includes a panel that has a pipe opening extending through the panel for having a pipe extending therethrough. The panel has a plurality of connection openings each extending through the panel. Fasteners can be extended through the connection openings for fastening the panel to an exterior wall of a building through which the pipe extends. A gasket is coupled to the panel and the gasket extends around the pipe opening. Moreover, the gasket surrounds the pipe when the pipe is extended through the pipe opening. A frame is removably attachable to the panel such that the frame covers the plurality of connection openings in the panel to enhance the appearance of the panel.
