The other end is flared and has a flat end face substantially perpendicular to the longitudinal axis of the conduit section. A coupling sleeve has an annular flange at its axially inward end which defines a central opening such that the coupling sleeve may slide freely to a limited extent over the length of decreased diameter of the other end of the conduit section. The axially outward end of the coupling sleeve has female machine threads formed thereon. Intermediate the inner surface of the flange and the threaded portion is a sloped shoulder.

  • Patent number: 4000919
    Abstract: A coupler for effecting hermetically sealed pipe or conduit interconnection by slip fit and without the use of tools. A coupler body member and a screw-on nut compress therebetween the outer marginal frusto-conical portion of a spring metal locking ring having arcuate segments directed angularly inwardly of the slipfit opening and defining a circle of slightly greater diameter than that of the pipe to be connected before the locking-ring is compressed in place, and slightly lesser in diameter than that of the pipe to be connected when the locking-ring is compressed in place. Pipe disconnect is accomplished by unscrewing the nut, which permits the locking ring to again assume a configuration wherein the arcuate segments define an opening of sufficiently greater diameter to permit withdrawal of the pipe.

  • Patent number: 3992043
    Abstract: Disclosed herein is an improved tube fitting of the swage variety which employs a body part, at least one ferrule designed to slip around a tube, and a nut used to compress the ferrule against the tube and the body part and thereby form a leak-tight connection between the tube and the body part. The nut is divided into two parts which are movably interconnected by a radially flanged tubular portion of one of the nut parts. This flanged tubular portion engages the ferrule and prevents rotation of the ferrule while it is being compressed against the body part by rotation of the other nut part.

  • Patent number: 3986737
    Abstract: An adapter for releasably coupling two tubular elements comprises a socket, a sleeve nut threadedly engaging the socket and an elastically deformable sleeve inserted in the sleeve nut. The socket consists of a smaller diameter and a larger diameter part, and the sleeve nut has an inner thread in threaded engagement with an outer thread on the larger diameter socket part. The axial length of the sleeve nut exceeds that of the larger diameter socket part, the inner thread is arranged at one sleeve nut end and an inwardly extending flange is at the opposite sleeve nut end. The sleeve is inserted in the sleeve nut between axially spaced shoulders formed by the flange and the larger diameter socket part. The outer diameter of the sleeve is slightly smaller than the inner diameter of the sleeve nut, the periphery of the sleeve defines a circumferentially extending trough-shaped recess, and the sleeve has a cylindrical inner wall.

  • Patent number: 3984130
    Abstract: Each section of an intermediate metal conduit with a constant diameter axial passageway has male pipe threads formed on its outer wall surface at one end. The other end of each conduit section has a short length of decreased outside diameter extending axially inwardly from the flat end face of the section, to form an external annular stop shoulder. A coupling sleeve has a pair of annular flanges which define central openings in mutual axial alignment but of different diameters such that the coupling sleeve may slide freely to a limited extent over the full external diameter of said other end of the conduit section. The coupling sleeve is retained captively on this other end by a resilent constrictable lock ring positioned in an annular lock ring groove disposed axially inwardly of the stop shoulder. When the coupling ring is unstressed, it protrudes, in part, radially outwardly of the groove and is in the path of movement of one of the flanges. The coupling sleeve can be retracted, i.e.
