Abstract
A porous spacer incorporates a vaporizable corrosion inhibitor. The spacer is designed to be placed on a leader pin between the members of a mold or die set. The spacer is compressed between the members when the latter are stored. The spacer releases the inhibitor, which prevents corrosion during the storage period. The spacer serves to maintain a vapor flow space between the members.
