A wire harness wall-passing structure and an installation method thereof. The wire harness wall-passing structure comprises: a sleeve pipe, a pouring sealant, and at least one sealing plug, wherein the sleeve pipe is alternately filled with the pouring sealant and the sealing plug along the axis direction of the sleeve pipe; and at least one first through hole is-formed in the sealing plug, and a wire harness which can penetrate through the pouring sealant and the first through hole in the sealing plug. According to the wire harness wall-passing structure, the sleeve pipe is filled with the pouring sealant and the sealing plug, so multi-stage sealing and multi-time sealing of the wire harness are achieved, the sealing performance of the wall-passing structure is greatly improved, and the wire harness wall-passing structure is more suitable for to-be-fixed devices such as a high pressure vessel.

A penetration fitting assembly includes a pipe gasket having an annular portion defining a central opening and first and second stem portions extending in opposite directions from the annular portion, an inner ring assembly configured to surround the pipe gasket and including first and second inner ring halves, a ring gasket assembly configured to surround the inner ring assembly and including first and second ring gasket halves, a wall gasket, an outer ring assembly configured to surround the ring gasket assembly and including first and second outer ring halves, and a clamp configured to surround the outer ring assembly. When the penetration fitting assembly is installed, the outer ring assembly compresses the wall gasket against the wall of the sump, the clamp compresses the ring gasket assembly between the inner ring assembly and the outer ring assembly, and the clamp compresses the pipe gasket against the pipe or conduit.

A feedthrough for feeding signals through a panel having opposite sides includes first and second parts. The first part can include a first body configured to be disposed in a first portion of an opening in a panel, a first lumen disposed within the first body, and a first engagement area comprising a first contact area. The second part can include a second body configured to be disposed in a second portion of the opening in the panel, a second lumen disposed within the second body, and a second engagement area configured to engage the first contact area, wherein engaging the first contact area with the second engagement area causes deformation of the first part, the second part, or both to hold the first part and the second part within the opening such that the first lumen and the second lumen are disposed generally concentrically with each other.

Precast utility enclosure aprons for buried utility enclosures that have an angled top surface to direct water, ice and debris away from the center of the apron and to limit damage to the apron and utility enclosure caused by impacts to the apron.

A heating, ventilation, and/or air condition (HVAC) controller assembly to reduce undesired air currents includes a front cover, a back plate configured to be removably secured to the front cover, HVAC controller circuitry, a plurality of wire openings, and an air intrusion barrier configured to extend across the wire openings. The HVAC controller circuitry is configured to be electrically coupled to a plurality of wires extending through a hole in the wall to adjust an environmental characteristic of in a controlled space. Each wire opening is configured to receive only a single wire and each wire is configured to extend through a different one of the wire openings. The air intrusion barrier is configured to receive the wires to generally form a plurality of seals against the wires. The wire openings are configured to substantially support the wires to reduce movement of the wires relative to the air intrusion barrier.

There is described a pipe connector for connecting first and second pipes slidably engageable one into the other, the pipe connector comprising: a side wall extending between a first end and a second end along a longitudinal axis and defining an interior space, the side wall being adapted to be inserted into a floor hole made into a floor; a floor flange extending laterally and outwardly from the first end of the side wall, the floor flange being adapted to rest on a floor surface when the side wall is inserted into the floor hole; and a guiding assembly secured to the side wall and comprising at least one resilient retaining finger for receiving the first pipe therebetween, the at least one resilient retaining finger being securable to the first pipe when the second pipe is engaged into the first pipe.

The grommet also includes an annular opposing portion that opposes a portion of the vehicle body panel surrounding the insertion hole, and is sandwiched between the vehicle body panel and a bracket fixed to the vehicle body panel. Furthermore, the grommet includes a coupling portion that couples the insertion portion and the opposing portion so as to close a gap between the insertion portion and the opposing portion. The opposing portion includes an annular sealing portion to be in intimate contact with the vehicle body panel. The coupling portion includes a plurality of pleat portions that extend along a circumferential direction of the opposing portion, and are adjacently arranged in a radial direction of the opposing portion, when viewed from an axial direction of the opposing portion.

A planar sealing panel member for cleaning the condenser coils of a cooling appliance. This member has at least one hole in its surface to accommodate a hose supplying compressed air. It also has affixation means on its surface so as to hold the sealing panel against the cooling appliance adjacent the opening(s) holding the condenser coils to form a substantially sealed enclosure along with the appliance structure within which the coils reside when cleaned using compressed air.
