5340-12-301-1291 5340123011291 123011291 is a straight metal item of various cross-sectional shapes, with serrations, flats, or the like, on each end. it is designed to withstand a severe twisting action along its longitudinal axis while held fast at both ends. it is used in lieu of a hinge pin and creates tension on a hatch(es), door(s), gate(s), or the like, when in a closed or open position. excludes torsion bar, suspension.
4730-99-301-1291 4730993011291 993011291 is an adapter having standard pipe threads on one end or an unthreaded end designed to accommodate a pipe. the other end has standard hose threads, an incomplete part of a threaded end connection that grips the hose directly, or is unthreaded and designed to accommodate a hose. it is designed to join a pipe or pipe fitting to a hose or hose fitting in a straight line.
5340-01-301-1291 5340013011291 013011291 is an item, usually made of metal, having a finished cap with spring tension prongs on the underside, or spring wire fitted into the sides of the walls. when inserted in punched or drilled holes in metal sheets or tubes, the expanding action of the prongs or spring wire holds the item securely in place. it is specifically designed to close a hole; to cover a hole through which passes a shaft, cable, or the like; or to provide a perforated cover for a vent or breather hole. excludes fastener, spring tension, trim.
5310-26-301-1291 5310263011291 263011291 is a washer having a centrally located hole with a solid or laminated cross-section and two flat parallel bearing surfaces. the hole must be 75 percent or less than the largest dimension and the bearing surface finish is greater than 32 microinch (0.8 micrometer). the thickness cannot exceed 25 percent of the largest outside dimension. when the largest outside dimension is less than 1/4 inch or 6mm, the thickness must be 0.006 inches (0.15mm) or greater and for items 1/4 inch (6mm) or larger, the thickness must be 0.016 inches (0.4mm) or greater. the maximum tolerance is applied to dimensions and used as a determining factor. items with separable lamination use shim. for items fabricated from ceramic or electrically rated materials by specification or industry standards use insulator (1), washer. excludes disk, valve, graphite impregnated and lubricated items.
1650-14-301-1291 1650143011291 143011291 is a replaceable device designed to remove solid particles from fluids ranging in density from heavy liquids to gases. the removal of particles is accomplished by porous material (metallic or non-metallic), stacked disks, wound wire, or the like, constructed so the fluid can flow through the device while the solid particles are retained. it may be designed to fit into a filter, fluid (or similar cavity), or it may have an integral outer casing and mounting facilities and be designed to connect directly to an engine, compressor, or the like. the degree of removal of particles must be nominally rated at less than 50 microns or absolutely rated at less than 75 microns. excludes filter element, air conditioning. see also strainer element, sediment.
