An air intake duct (50) for a motorcycle supplies air taken in through an air inlet (24) in a front portion of a vehicle body to an engine (E) located at a center portion, in a longitudinal direction of the motorcycle, of the vehicle body. The air intake duct (50) includes a duct front (69) having the air inlet (24) formed at a front end thereof, and a duct body (70) removably coupled to a rear end portion of the duct front (69). The duct body (70) extends in the longitudinal direction so as to pass through an outer lateral side of the engine (E) and is removably connected at a rear end portion thereof to an air cleaner (40). In a state in which the duct body (70) is removed from the air cleaner (40), a cleaner element (87) can be attached and removed.

Downspout connector consists of an attachment system for joining to open end of a downspout. The apparatus is hand-fastened to downspout without need of physical or permanent drain modification. The apparatus interface permits fluid movement through duct(s) to threaded hose connector. A conventional hose joins with threaded hose connector(s) for fluid distribution to remote locations. Downspout connector presents an easier, more efficient device for diverting and dispersing rainwater.

A joint restraint for deforming an outer diameter of a pipe for insertion into a socket. The joint restraint can selectively mount to a portion of an irregularly shaped pipe having a maximum outer diameter that differs from a desired substantially constant outer diameter. The joint restraint can have a circumferential ring body surrounding a central axis. A plurality of jacking assemblies can be secured to a portion of the ring body. Each jacking assembly can have a frame and a jacking bolt. The frame can have a threaded aperture that can receive the jacking bolt. Each jacking bolt can be selectively actuatable for radial movement relative to the central axis to deform the pipe proximate the maximum outer diameter of the pipe by selectively urging an outer surface of the pipe to the desired substantially constant outer diameter.

A fluid conditioning assembly includes a fluid conditioning device defining a passage and having a first end and a second end. A control element is supported within the passage. At least the first end includes an integral radially outwardly directed flange. The integral radially outwardly directed flange is configured to be operatively and releasably coupled to a first radially outwardly directed flange of a first duct section. A technician may release the fluid conditioning device from the first duct section to remove the fluid conditioning device from the ventilation duct system for accessing the control element of the fluid conditioning device.

Fluid connector assembly and methods are usable to establish a sealed fluid connection. The connector assembly comprises a female union connector having an axial bore extending therethrough, internal threads, and an internal shoulder. The connector assembly also comprises two male connectors, each male connector having an axial bore extending therethrough and external threads. The connector assembly further comprises two ring-shaped seals adapted to form a fluid seal between the female union and the male connectors. The first seal contacts the first side of the internal shoulder and a front end of the first male connector to form a fluid seal therebetween. The second seal contacts the second side of the internal shoulder and a front end of the second male connector to form a second fluid seal therebetween.

A mechanical coupling for joining pipe elements end to end has a channel that receives a ring seal. The channel is defined by oppositely disposed sidewalls and the ring seal has lobes on opposite sides. The lobes have surfaces facing the side surfaces of the channel. When the ring seal is seated within the channel, each lobe surface contacts a respective side surface such that the lobes deform inwardly toward the center of the channel.
