4720-01-558-6506 4720015586506 015586506 is a length of nonmetallic hose with fittings on one or both ends. for items without fittings, see hose, nonmetallic. excludes hose assembly, air duct; and hose assembly, air duct, air breathing.

5961-14-558-6506 5961145586506 145586506 is two or more diode semiconductor devices designed to function as a unit in changing alternating current to direct current. the diode devices are internally connected in series, and are permanently cased, encapsulated, potted, or molded together to form an inseparable unit. these units may be designed as either half-wave or full-wave rectifiers and may be mounted to form either single phase or three phase bridges. for interconnected items arranged in stack(s), see rectifier, semiconductor device. for items fabricated in the form of a monolithic or thin film structure that perform the function of a circuit, see integrated circuit (as modified). excludes semiconductor devices, unitized; semiconductor device assembly; and rectifier network, unitized.

5310-99-558-6506 5310995586506 995586506 is a washer of any peripheral shape having a centrally located hole. both bearing surfaces are parallel and flat, but one or both of the bearing surfaces must be broken by a counterbore, countersink, or similarly shaped recess. the thickness must not exceed 25 per cent of the outside diameter or the largest outside dimension. the maximum limit of the tolerance or range applied to the thickness and/or largest outside dimension must be used to determine compliance. excludes washer, concave, retainer, packing, and thrust type washers. see also spacer, sleeve; and spacer, stepped.

5905-01-012-9754 5905010129754 010129754 is a resistor whose ohmic value cannot be adjusted or varied. the resistance element consists of either a thin layer of conductive material, containing either binders or insulating materials, deposited on an insulated form; or an alloy of metal and ceramic materials, usually fused to an insulated form. opposition to the flow of current is an inherent property of the materials used and is manifest by the heat dissipation in the resistor. see also attenuator, fixed and resistor, fixed, composition. excludes carbon composition type resistors.
