A connecting structure includes a housing, a cooler, an inner refrigerant pipe, an outer refrigerant pipe, and a joint pipe. The joint pipe is attached to a through hole of the housing. The inner refrigerant pipe is fitted to the joint pipe from a housing inner side. The outer refrigerant pipe is fitted to the joint pipe from a housing outer side. A tip of the inner refrigerant pipe and a tip of the outer refrigerant pipe define a gap inside the joint pipe. An end surface of a flange or a rib of the outer refrigerant pipe in a refrigerant-pipe axis direction abuts with an end surface of a flange or a rib of the joint pipe in the refrigerant-pipe axis direction.

A piping connection device includes a female block member fixed integrally with a male block member, and a first pipe is inserted into the female block member. The piping connection device further includes a drain passage through which a part of an outer peripheral surface of the first pipe communicates with an outer surface of the female block member. The drain passage is disposed in a portion higher in heat capacity than the other portions in the female block member.

A block fitting for an air conditioning system includes a male block portion and a female block portion. The male block portion has a first annular pilot. The female block portion has a first annular collar that receives the first annular pilot of the male block portion. The first aperture of the male block portion and the first aperture of the female block portion are substantially concentrically aligned. A first seal structure is disposed between the first annular pilot of the male block portion and the first annular collar of the female block portion. A fastener engages the male block portion with the female block portion to form a substantially fluid tight seal. One of the of the male block portion and the female block portion has a stabilizing heel formed adjacent a side surface thereof. The stabilizing heel militates against transverse dynamic loading of the seal structure in operation.

A connector for connecting a fluid flow duct to a fuel stringer duct. The connector comprises a body having an internal channel for fluid passage between a first opening and a second opening of the body. A flange surrounds the first opening, the flange configured for insertion into a hole formed in a wall of the fuel stringer duct. An outer surface of the flange is provided with a first sealing member that surrounds the flange, the first sealing member configured to form a seal between the outer surface of the flange and an internal surface of the hole formed in the wall of the fuel stringer duct.

A hose connection joint structure for a battery cooling system of a battery pack including an upper case configured to seal an upper portion of the battery pack, a hose connection part disposed on an upper surface of the upper case and being configured to introduce cooling water from the outside, and a sealing member disposed between the upper case and the hose connection part, wherein the sealing member comprises a bracket in contact with a lower surface of the hose connection part and being configured to block the cooling water from leaking from the lower surface of the hose connection part, and a gasket surrounding the bracket and being in contact with the upper surface of the upper case to block the cooling water from leaking from the upper surface of the upper case.

A plurality of coolant piping lines are connected via valve, body flange members, which include respective recesses which are notched toward respective piping line insertion holes into which respective coolant piping lines are inserted, projections which are projected from respective recesses, and screw insertion holes which are arranged on a respective projection or recess, recesses and projections being combined with one other to make continuous screw insertion holes into which a fixing screw is inserted to fix the flange members.

A diverter for a rain barrel includes a scoop portion configured to fit within a gutter downspout, a rain barrel fitting portion configured to fluidly attach the scoop portion to the rain barrel, and a wing extending outwardly from the scoop portion to direct a flow of water in the gutter downspout towards the scoop portion.

A connection arrangement device for making a secure connection with at least one tube in a fluid line includes at least one adapter body having a passage bore forming at least one fluid channel with at least one outlet and a receptacle, a mating block formed with at least one longitudinal channel receiving the at least one adapter body, and the at least one adapter body includes a retention feature formed in the receptacle and coupled to the mating block such that the at least one adapter body is securely retained in the mating block. In particular, the retention feature of the adapter body is formed with an annular lip at an end portion of the receptacle to be coupled with the mating block.

The current disclosure relates to Hydronic Waveguide pipe penetration assembly. The pipe penetration assembly provides protection from the penetration of EMI and RF emission into a shielded enclosure. The Hydronic Waveguide passes through a wall of the shielded enclosure utilizing a gasket between the wall and the waveguide and is fastened securely utilizing a number of bolts and nuts forming a mechanical fastening to the shielding perimeter. The gasket provides a low-resistance electrical connection from the Hydronic Waveguide assembly and the enclosure shield to mitigate EMI and RF interference and/or penetration.

A fluid coupling system is provided that includes a first coupler that can be mounted to a first support, and a second coupler that can be mounted to second support. Each of the first and second couplers include a coupler body extending through openings of the respective support walls, and gaskets positioned over the coupler body and on opposing sides of the respective walls of the first and second supports. The gaskets form a fluid tight seal between the first and second coupler bodies and the respective supports, while permitting pivoting of the first and second couplers relative to the respective supports to accommodate for misalignment of the first and second couplers. In some embodiments the first and second supports can be walls of a container or can include framing that supports the containers.
