Abstract: Connection for fluids comprising a movable hollow joint (1) equipped with a lateral tubular duct (15) and two conical through-holes, opposite and coaxial (2) and (2') whose axis is perpendicular to that of the lateral duct; a clamping screw inserted in the through-holes (2) and (2') of the joint (1). The shank (3) of said screw is provided with a central duct (12) coaxial with the axis of said holes (2), a transversal hole (14) which connects said duct (12) with the internal chamber (13) of the joint and two round grooves (10) and (11) at said through-holes (2) and (2'); and flexible round gaskets (9) and (940 ) inserted in said grooves (10) and (11).

Abstract: Mobile joint for connectors including a central body (1) having a compartment (2) into which converge the two tubes (3, 4) to be connected, fixed to the central body, and a hollow bolt in the duct (6) of which is inserted one (4) of the tubes which is ensured by means of a drawing die for enlarging (15).The seals are guaranteed by means an annular elastic gaskets (11, 12) arranged in cavities (10, 13) machined respectively on the upper surface (9) and the lower surface (14) of the bolt head (7).

Abstract: A fluid connector is provided which is especially adapted for use with low-pressure fluids. The fluid connector comprises a bored mobile joint possessing an internal chamber communicating with a tubular conduit and upper and lower coaxial, opposed bore-holes whose common axis is substantially perpendicular to said tubular conduit. A screw brace is inserted into said bore-holes. The leg portion of the screw brace possesses an internal conduit which is co-axial with the common axis of the bore-holes and which communicates with the internal chamber, said leg portion further possessing upper and lower annular grooves and a threaded portion starting below the lower annular groove. A metallic retaining ring is positioned below the upper bore-hole and is disposed within the upper annular groove.

Abstract: The pipe (2) is inserted in the flange hole (1) and the pipe-flange seal is assured by an elastomeric ring (7), compressed inside a circular groove (4), made along the internal surface of the flange hole and by heading and expansion of the pipe inside the said hole. The internal surface of the hole may have another two circular grooves, positioned up-stream and down-stream of the first groove (4): one (3) being closed and the other (5) open on one face (6) of the flange. During heading the pipe (2) expands into the groove (3) and folds along the edge of the open groove (5).

Abstract: The pipe (2) is inserted in the through-hole of the flange (1) and the pipe-flange seal is assured by a fixing ring nut (6) screwed into the upper portion (5) of the hole.The hole, in the part opposite the threaded area (5), has an area (4) with a diameter equal to that of the pipe (2) and a truncated-cone coupling area (4) between the two areas (5) and (7). A ring (8) of elastomeric material is inserted inside the truncated-cone portion (7) and an annular projection (9) on the pipe (2) acts thereon, pushed by the screwing action of the ring nut (6).
