    Abstract: A swivel coupler for connecting a pair of rigid electrical conduits especially in a confined space, includes a tubular body member with an inner sleeve of rigid plastic material, which protrudes slightly beyond the ends of the body. A pair of nuts are slidably mounted on the outer peripheral surface of the tubular body between outwardly directed radial flanges adjacent opposite ends of the body and which thread a corresponding conduit. A method of fabricating the coupling is to reverse opposite body ends 180* to abut the outer peripheral surface of the body, have one end with an outside diameter smaller than the inside diameter of the nuts, position the nuts back to back on the body, and then enlarge the reduced end of the body to its normal diameter or larger.

    Abstract: A valve housing for an automobile hydraulic power steering gear and integrated spool valve is provided with a tube receiving opening having a threaded outer portion, an annular coaxial pilot portion at the inner end of the threaded portion, and a coaxial conical guide portion converging inwardly from the pilot portion and opening axially into a transverse bore for a spool valve that controls operation of the gear. The outer end of the conical opening is of smaller diameter than the pilot opening and is defined by an annular clamping shoulder of the housing at the inner end of the pilot opening. A tube for conducting high pressure hydraulic fluid is provided with a radial enlargement spaced from its inner end. An O-ring is seated on the tube between the enlargement and a flared inner end of the tube. The flared end retains the O-ring on the tube until the coupling is assembled and also shields the O-ring from injury when the flared end is inserted into the tube receiving opening during the assembly and guided by the conical opening to a position whereat the annular enlargement seats at the clamping shoulder. An externally threaded nut engaged within the threaded opening clamps the enlargement against the shoulder and deforms the Oring into sealing engagement with the adjacent sidewalls of the tube and concial guide opening.
