4420-01-252-4803 4420012524803 012524803 is an apparatus designed to lower the temperature of a fluid by bringing it into proximity with another fluid of lower temperature so that heat transfer is effected by conduction through the walls of separating chambers. excludes air conditioning equipment, refrigeration equipment, and radiators.

5310-14-252-4804 5310142524804 142524804 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.

5310-14-252-4803 5310142524803 142524803 is a nut, round in shape, having all or part of its outer surface knurled. it may have provisions for external wrenching. for items having a thickness (or height) exceeding two times the outside diameter, use post, electrical-mechanical equipment. see also nut (1), plain, round. (when height or thickness, and/or outside diameter is designated as a tolerance dimension, the maximum dimension will be used to determine compliance).
