Abstract
A device on a conduit end for joining the conduit (1) to a coupling (4) or some other receiver of the end of the conduit, which is made of aluminum or an aluminum alloy. Two external annular beads (2, 2′) are pressed out from the conduit wall on the conduit end and accommodate between themselves an O-ring (3). In an arrangement for joining, the receiver (4) has a conical inlet and means, which together with the rear annular bead (2) form engaging means for a tightening means.
Claims5
A fluid distribution system comprising an annular receiver having an axial bore, a conduit having an end for disposing in the receiver bore, the end having first and second external annular beads formed in a spaced relationship thereupon for receiving a sealing member therebetween for engaging the receiver bore to form a seal, and means for detachably retaining the conduit end in the receiver.
A fluid distribution system comprising an annular coupling having an axial bore and an external groove, a conduit having an end for disposing in the coupling bore, the end having first and second external annular beads formed in a spaced relationship thereupon, a sealing member for engaging the coupling bore to form a seal, the member disposed between and engaging the first and second annular beads, and a rider for detachably retaining the conduit end in the coupling, the rider comprising a first set of legs for engaging the first bead of the conduit and a second set of legs for engaging the groove of the coupling.
A fluid distribution system comprising an annular coupling having an inwardly tapered axial bore and an external groove, a conduit having an end for disposing in the bore, the end comprising a first annular bead formed on an external surface of the conduit, and a second annular bead formed on an external surface of the conduit in a spaced relation to the first bead, a sealing member for engaging the coupling bore to form a seal, the member disposed between and engaging the first and second annular beads, and a rider comprising a first set of legs for engaging the first bead of the conduit and a second set of legs for engaging the groove of the coupling, thereby detachably retaining the conduit end in the coupling.
A fluid distribution system comprising an annular coupling having an inwardly tapered axial bore and a pair of axial openings, a conduit having an end for disposing in the bore, the end comprising a first annular bead formed on an external surface of the conduit, and a second annular bead formed on an external surface of the conduit in a spaced relation to the first bead, a sealing member for engaging the coupling bore to form a seal, the member disposed between and engaging the first and second annular beads, and a U-shaped rider comprising a set of legs for inserting into the axial openings, thereby engaging the first bead of the conduit and detachably retaining the conduit end in the coupling.
