This is the first modification of the specification since the 1989 issue of MS 35489J, which is now obsolete. The new MS 35489K is to be used in conjunction with procurement specification NASM 3036 (formerly MIL-G-3036), “Grommets, Rubber, Hot-Oil and Coolant Resistant.” FYI: MS 35489 also replaced MS 35490, again now obsolete.
Marginal notations are not used in this revision to identify changes with respect to the previous issue due to the extent of the changes.
“MS” stands for Mil Spec drawing. This series of military documents covers a wide range of products and follows a drawing type of format. In this case, there are 2 sectional views of the grommet on the first page, a table of dash numbers and dimensions on page 2, requirements for material, color, part number and tolerances on page 3, and a table of replacement part numbers on page 4.
