Abstract: A lightweight pup joint comprising a length of pipe with male and female union subs on the ends and having integral metallic fluid contacting components. The pipe is formed with a minimum wall thickness required for the intended pressure rating and includes a radially enlarged portion on one end to form a male sub. The other end of the pipe includes a small radial flange sized so a union nut can be moved over the flange. A split female sub is assembled over the flange and held together by a snap ring. An annular sealing member seals gaps between portions of the female sub, seals an interface between the flange and the female sub, and seals a gap between the flange and a male sub of an adjacent pipe. At least one ear on the pipe fits into a slot in the female sub to prevent rotation of the female sub when the union nut is threaded onto the female sub.

Abstract: A feedthrough assembly for a conduit has, as is known, a wall formed with a throughgoing passage extending along an axis and having a radially inwardly directed wall surface. An elastomeric adapter sleeve has an outer surface complementarily radially outwardly engaging the wall surface, an inner surface snugly surrounding and engaging a conduit passing axially through the passage, and an axially backwardly open and annular groove between the surfaces and of a predetermined radial width in a relaxed condition of the sleeve. A tightening ring of a radial dimension greater than the width of the groove fits so tightly in the groove as to press the sleeve radially outward against the surface of the passage and inward against the conduit. The ring is formed of at least two similar sector-shaped ring parts having the same radius of curvature as the groove and having ends provided with angularly interfitting formations.

Abstract: A coupling apparatus is provided for quick coupling of a plug container or the like to a casing collar. A body of the plug container is located above the casing collar.

Abstract: A connection at which two hoses or similar conduits are coupled includes a male coupling on one of the hoses and a female coupling on the other hose. The male coupling consists of a body that receives the hose and a tapered bushing which threads into the hose and spreads it outwardly into the body. The body has a threaded end section. The female coupling consists of a threaded ring having an inwardly opening groove, a ferrule that receives the hose and has at its one end a flange which fits into the groove of the ring, and a tapered bushing that threads into the hose and expands it against the ferrule. When the hose and bushing are out of the ferrule, the flange of the ferrule will fit into the ring, but when the hose is expanded outwardly by the bushing, the flange of the ferrule is captured in the groove of the ring. The ring threads over the threaded end section of the male coupling and forces the ends of the threaded section and the ferrule together.

Abstract: For a plumbing trap, such as under a sink or other similar installations, a split slip nut and seal assembly for joining two tubular members such as pipes or tubes one within the other; wherein a split seal is inserted between the tubes laterally and then a slip nut formed in two split sections is applied on a threaded male sleeve surrounding the tubular members and the seal to compress the seal and to secure the tubular members together. The split sections of the nut are fastened together by releasable fasteners engaged on opposed lugs projecting from the split nut. When access to the trap is desired, the split slip nut and seal assembly avoids the necessity of dismantling the entire installation as is required with conventional slip nuts.
