A tube end form, including a first section including a first radially outward facing surface, a second section including a second radially outward facing surface, and a shoulder axially arranged between the first and second sections, the shoulder including a first frusto-conical surface arranged at a first angle relative to the first radially outward facing surface, and a second frusto-conical surface arranged at a second angle relative to the first radially outward facing surface.

A piping joint connects a resin tube to a connection pipe having a protrusion formed on an outer peripheral surface of a distal end portion of the connection pipe. The piping joint includes a housing press-fitted into the resin tube and an elastically extendable and contractible seal member into which the connection pipe is inserted such that sealing is performed between the connection pipe and the seal member. The housing has a first housing portion positioned in one end portion and having an outer peripheral surface side press-fitted into the resin tube and a second housing portion positioned in the other end portion. The seal member has a first seal portion inserted on an inner peripheral surface side of the second housing portion.

A quick-connect system for a high pressure connection includes a port and a collet. The port defines an inlet opening at an outer longitudinal end of the port and includes an inner wall having a first sloped surface at least partially defining a collet cavity. The first sloped surface has a first diameter at a first end nearest the inlet opening and a second diameter, which is greater than the first diameter, at a second end opposite the first end. The collet includes a head portion and a plurality of legs extending distally from the head portion, and each leg of the plurality of legs includes a distal foot portion. In a connected state, the foot portions of the plurality of legs are located in the collet cavity, and the foot portions define an outermost diameter that is greater than the first diameter.

A connecting arrangement of a gas pipe of a gas appliance to a gas connection of a gas device of the gas appliance comprising a connecting device to connect the gas pipe to the gas connection. To achieve a safer and more reliable connection between the gas pipe and the gas connection, the connecting device is inserted between the gas pipe and the gas connection. The invention also comprises a gas appliance with such a connecting arrangement and the assembly process of the connecting arrangement.

An apparatus comprises an engine, an exhaust manifold fluidly coupled thereto, and an auxiliary system positioned downstream of and fluidly coupled to the exhaust manifold. A slip joint assembly fluidly couples the exhaust manifold to the auxiliary system and includes a slip joint male portion fluidly coupled to the exhaust manifold which includes a plurality of lobes positioned on an outer surface of the male portion. The male portion defines a first passageway in fluidic communication with the exhaust manifold. The assembly also includes a slip joint female portion fluidly coupled to the auxiliary system and including a second passageway. The male portion is insertable into the female portion for fluidly coupling the male portion to the female portion. Only the plurality of lobes contact an inner surface of the second passageway. Moreover, the male portion is axially slidable within the second passageway while maintaining the fluid coupling therebetween.
