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.

A grommet unit to be attached to an attachment surface of an attachment-target body, the grommet unit including: a tubular grommet having a groove on a surface thereof; a bracket to be overlaid onto the grommet and press the grommet against the attachment-target body in a first direction; and a communication passage formed by covering the groove of the grommet with the bracket, wherein the communication passage has a first end that is in communication with a space between overlapping surfaces of the bracket and the attachment surface, and a second end that is in communication with a portion where the grommet and the bracket are not overlaid on each other.

A grommet according to one aspect of the present disclosure includes: an annular mounting portion that is to be fixed to a surrounding portion of an insertion hole of a vehicle body panel; and a tubular stress-absorbing portion that includes a tubular side wall that extends from an inner circumferential rim portion of the mounting portion toward one side in an axial direction, and a bottom wall that partially closes off the tubular side wall at a front end of the tubular side wall. Furthermore, the grommet includes tubular insertion portions that are provided integrally with the bottom wall, and that cover the outer circumferences of wire harnesses inserted into the insertion hole. The mounting portion includes an annular seal portion that comes into close contact with the surrounding portion of the insertion hole of the vehicle body panel. The side wall is flexible.

A cover for HVAC conduits and wiring exiting a structure is provided permitting a simplified solution to protect the line set in an aesthetically pleasing manner. A two-part face plate fits around the conduits and wiring. Each face plate includes a partial cone-shaped protruding member that circumscribes the conduits and wiring once installed. The cover also includes a sleeve that fits around the conduits, distal the cone-shaped protruding members in a tight-fitting manner providing further protection. The cover is easily removeable for a service technician to maintain and repair the conduits or wiring in future servicing.

An end seal placement tool for placing an end seal in a host pipe within a manhole includes a pole with opposite proximal and distal ends. An end seal holder is disposed at the distal end of the pole. The end seal holder includes an end seal chamber configured to hold the end seal. The end seal holder is sized and shaped to be at least partially inserted into the host pipe. A launcher is arranged with respect to the end seal holder for ejecting the end seal from the end seal holder into the host pipe.

Disclosed is an intake joint structure capable of blocking backflow of lubricating oil 18 at a connection position between an air inlet 12 of a turbocharger and a suction pipe 24. A backflow-preventive plate 25 is integrally molded to have a cylindrical portion 25a fitted over the air inlet 12 and a tapered portion 25b curved inward from an upstream end of the cylindrical portion 25a and converged downstream to provide an open end. A downstream end 24a of a suction pipe 24 is molded by soft material over a predetermined range using exchange blow molding. The cylindrical portion 25a of the backflow-preventive plate 25 is fitted over the air inlet 12 through a grommet 26 (first soft layer) and the downstream end 24a of the suction pipe 24 is fitted over the cylindrical portion 25a and is banded by a hose band 27.

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.
