The present disclosure provides a heat exchange pipe joint and a battery pack. The heat exchange pipe joint is fixedly installed to an installation plate. The heat exchange pipe joint includes a first pipe and a second pipe that are separately formed and in communication with each other. The first pipe is detachably connected to a second side of the installation plate, and the second pipe is detachably connected to a first side of the installation plate. When the heat exchange pipe joint of the present disclosure is applied to the battery pack, the heat exchange pipe joint in a split-structure requires a small operation space for detachment and installation. In this case, a process of taking out the entire heat exchange pipe joint from the case can be avoided, so that the battery module and other components inside the case do not interfere with the detachment and installation of the heat exchange pipe joint. In this way, the detachment and installation of the heat exchange pipe joint can be easy and convenient, thereby facilitating the reparation process thereof.

A through the hole vent pipe fitting seal includes a generally hollow cylindrical main body having an annular flange extending outwardly thereof perpendicular to the axis of said main body. An annular sealing member is positioned against a lower surface of the annular flange. An annular clamping member is movably attached on the main body to clamp the seal around a hole in a construction material on which the fitting is to be mounted.

A method of providing a drain pipe passageway through a concrete slab wherein a plastic pipe of predetermined diameter, which is greater than the underlying drain pipe, is positioned in an upright manner within a location of a concrete slab to be poured. Concrete is poured around the pipe to a desired level leaving a portion of the pipe exposed above this level, and the concrete is permitted to solidify. Thereafter the exposed portion of the pipe is cut off leaving an upper opening of the pipe flush with the upper surface of the concrete slab. The upper opening of the pipe is closed off with a plastic cap and a passageway of predetermined diameter, which is smaller than the pipe diameter, is drilled through the cap at a newly calculated position of alignment, and a plastic pipe having an outside diameter which will mate with this smaller diameter of the passageway is inserted through the cap passageway and cemented in position.

An adapter includes a plurality of individually separable collars that allow for easy, on-site adjustment of the length of the adapter based on a measured offset of an outlet of a water supply assembly to which the adapter is attached. An exterior of each collar is configured to sealingly engage the outlet of the water supply assembly, such that the adjustment to the length of the adapter does not compromise the ability of the adapter to be sealingly coupled to the water supply assembly. A slip fitting provided along a downstream end of the adapter allows the plumbing fixture to be installed flush against a wall in a desired orientation, without compromising the sealing engagement between the adapter and either of the plumbing fixture or outlet opening.

Disclosed is a seal for an engine firewall. The seal including a proximal part having a recess; a distal part having a notch; and a flexible intermediate part integrally extending between the proximal part and the distal part.

A through bulkhead connector for a spa includes a first fitting member and a second fitting member slidably connected to the first fitting member. The first fitting member includes a flange and an adapter portion extending from the flange and defining a passageway through the adapter portion and flange. The flange includes a receiving slot formed therein and which is open at one end for receiving a correspondingly shaped and dimensioned portion of the second fitting member.

Disclosed is a through fastening unit including a pipe-receiving structure located at a ceiling, the pipe-receiving structure being fixed to the ceiling while surrounding a reducer, an attachment and detachment member configured to surround the reducer between the pipe-receiving structure and the reducer, and a tightening pipe configured to cover the attachment and detachment member together with the reducer in the vicinity of the attachment and detachment member and to surround the reducer between the pipe-receiving structure and the attachment and detachment member, the tightening pipe being screw-engaged with the pipe-receiving structure, wherein the tightening pipe moves relative to the pipe-receiving structure in a longitudinal direction of the reducer between the pipe-receiving structure and the attachment and detachment member to bring the attachment and detachment member into tight contact with the reducer or to separate the attachment and detachment member from the reducer.

Disclosed is a seal for an engine firewall. The seal including a proximal part having a recess; a distal part having a notch; and a flexible intermediate part integrally extending between the proximal part and the distal part.

A heating, ventilation, or air conditioning system having a housing , for a motor vehicle having a firewall, wherein the firewall has at least one opening, wherein the housing projects through the opening, wherein the housing has at least a first housing part and at least a second housing part, wherein the first housing part rests against the firewall with a seal interposed and is attached to the firewall, wherein a portion of the first housing part projects through the opening, and the second housing part is attached in a sealed manner to the portion of the first housing part that projects through the opening.
