Abstract: A connector assembly including a plate (10) having an orifice (10a) and a spigot (12), the spigot (12) having an internal flow path for liquid, and connector means (14) for connecting the spigot (12) to the metal plate (10) so as to guide the liquid flowing in the flow path through the orifice (10a), the connector (14) including a protruding collar structure (16) surrounding the orifice (10a). The connector means (14) further includes a ring-shaped snap-on module (18) configured to be fitted over the collar structure (16), the snap-on module (18) including a cylindrical insertion part (18a) configured to be inserted into an orifice (10a) of the collar structure (16), wherein a remote end of the cylindrical insertion part (18a) in the insertion direction is provided with first snap-on structures engaging with the collar structure (16).

Abstract: An embodiment includes a spool that may expand and contract to ease removal and addition of components to an oilfield manifold. The spool may comprise: a first conduit to couple to a first flange via a first ring joint gasket; a second conduit to couple to a second flange via a second ring joint gasket, the second conduit including threads; a third conduit coupled to the first and second conduits; and a fourth conduit including threads, the threads of the fourth conduit directly engaging the threads of the second conduit. The first, second, and third conduits collectively form a channel that couples first and second opposing ends of the spool to one another and which includes a long axis. Rotating the fourth conduit about the long axis moves the second conduit linearly along the long axis.

Abstract: A joint assembly is connected to a hose assembly. The hose assembly includes a hose in a sleeve. The joint assembly includes an internal joint and an external joint. The internal joint includes an external thread, a shank at an end, and an annular ridge on the shank. The external joint includes an internal thread, a connective portion at an end, a shank at another end, and a conical internal face. The shank of the external joint is inserted in the sleeve. The external joint receives the hose. The shank of the internal joint is inserted in the hose. The external thread of the internal joint is engaged with the internal thread of the external joint to cause the annular ridge of the internal joint to press the hose against the conical internal face of the external joint.
