The adapter assembly extends outward from an inner structure such as an outer barrel or nipple base to attach the inner structure to a housing such as a bowl. Each sized inner structure fits a specified bowl for attachment of the inner structure to the bowl. The adapter assembly extends outward from the inner structure to fit one of the available sizes needed for attachment to the bowl. The adapter assembly is characterized by a first attachment body and a second attachment body. The adapter assembly attaches to the exterior of the inner structure to increase the surface exterior of the outer surface for attachment of the inner structure to the bowl.

A pipe/fitting having an end having a modified crimp for securing both flexible ducts and pipes. Specifically, the pipe/fitting includes an end having a series of annularly disposed pipes. The modified crimp includes an outwardly facing channel in the base of the series of crimps configured to secure a flexible duct between the channel and a fastener received in the channel. The end also includes a pipe coupling system at the base of the series of crimps configured to couple a pipe to the conduit.

A diesel fuel cross-drop prevention kit that provides a multitude of couplings and fittings designed only for a single type of fuel. The kit includes a drop-elbow coupler, a storage-tank inlet tube, a primary key slot, a primary key protrusion, a retractable pull pin, a hose, a gravity-drop tube fitting, a secondary key slot, and a secondary key protrusion. The primary key slot traverses into an internal surface of the drop-elbow coupler. The primary key protrusion is externally and laterally connected to the storage-tank inlet tube. The storage-tank inlet tube is positioned within the drop-elbow coupler with the primary key protrusion being positioned within the primary key slot. The secondary key slot traverses into a first female coupler tube of the hose. The secondary key protrusion is externally connected to the gravity-drop tube fitting. This allows the first female coupler tube to fit over the gravity-drop tube fitting.

Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as torque-less connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability.

A snout apparatus for guiding high pressure flexible lances between a lance drive apparatus and a flexible lance positioner apparatus includes one of a male tubular connector and a female tubular connector fitting adapted to fasten to a flexible lance drive apparatus, another one of a male and a female tubular connector fitting adapted to fasten to a flexible lance positioner, and a plurality of segments connected together in series so as to connect in series between the one and another connector fittings. Each segment may include a cylindrical tube portion sized to receive and pass therethrough flexible lances and a tubular collar portion connected to the tube portion. The collar portion has peripheral arcuate closed slots adjacent to and spaced around a distal end of the collar portion. Shoulder bolt fasteners are each fastened to a next segment tube portion and extend through one of the closed slots.

A breech lock coupling comprising a stem receivable in a hose, a ferrule configured to receive the stem and hose, a connector, the ferrule comprising a plurality of ferrule lugs on an inner surface, each ferrule lug separated from an adjacent ferrule lug by a ferrule lug gap, the connector comprising a plurality of connector lugs on an outer surface, each connector lug separated from an adjacent connector lug by a connector lug gap, each ferrule lug gap arranged to receive a connector lug and each connector lug gap arranged to receive a ferrule lug upon engagement of the ferrule with the connector, each connector lug axially alignable with a ferrule lug upon rotation (R) of the connector within the ferrule, the connector engages a stem end, a fastener for fixing a connector position relative to the ferrule.

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.
