A flow control device for installation in a bore in a compliant housing comprises a central flow control mechanism and generally cylindrical body with an outer surface having a base diameter and comprising a plurality of annular ridges, coaxial with the device, arrayed in an axial series and separated by grooves, and projecting radially outward above the base diameter of the device, and a method of securing a flow control device within a bore formed in a compliant housing, comprises the steps of forming the outer surface of the device to have a generally cylindrical shape and a base diameter and comprising a plurality of annular ridges, coaxial with the device, arrayed in an axial series, separated by grooves and projecting radially outward above the base diameter of the device, the base diameter formed or selected to be slightly less than the inside diameter of the bore, and pressing the device into the bore to the desired location at a rate not exceeding the rate at which the material of the housing displaced by the ridges can flow into the grooves.

A method for removably securing a component within a bore having a shoulder, includes: forming a housing with a generally cylindrical wall with an open first axial end and a partially closed second axial end having an annular shoulder, and an annular lip section at the first end of the cylindrical housing wall, the lip section having a radially outwardly projecting and circumferentially extending annular ridge, an inner chamfer creating a frustoconical surface with a base toward the housing first axial end and an outer chamfer creating a frustonconical surface with a base toward the housing first axial end; and, inserting the housing into the bore, engaging the bore shoulder, engaging the inner chamfer of the housing lip section with a tool for applying axial force, the tool having a conical surface corresponding to and engageable with the housing inner chamfer, and applying axial force against the inner chamfer by means of the conical surface of the tool.

A device is formed that will accept or itself be a component to be inserted into and removably secured in a bore, the device being a cup shaped housing with a cylindrical wall and a floor in which there may be a central opening, the open end of the housing has an inner chamfer and an outer chamfer and an outwardly protruding ridge extending around the open end, and the device is used by inserting into a bore, with or without a separate component secured inside the housing, and forcing the ridge to expand into the bore wall by means of a tool having an outer conical surface corresponding to the inner chamfer, after which the housing can be removed by forcing the open end and ridge to compact by means of a tool having an inner conical surface corresponding to the housing outer chamfer.
