419pc Assorted Metric O Ring Kit - 32 Sizes, 3mm to 50mm

419pc Assorted Metric O Ring Kit - 419 metric O rings covering thirty two sizes from 3mm up to 50mm inside diameter, in four cross sections from 1.5mm to 3.5mm.

An O ring sits in a machined groove and seals as it is squeezed between two faces. Two figures decide whether one fits: the inside diameter and the cord thickness, or section. The same inside diameter in a thicker section is a different seal and will not sit correctly in the groove, so both are listed against every size below.
