The CMS collaboration intends to improve the muon trigger efficiency in the forward region. In order to achieve this goal, 144 new Resistive Plate Chambers (RPCs) will be installed as a 4th layer in the endcap system, to trigger high momentum muons from the proton-proton interaction. In this paper, we present the detailed procedures used in the production of the CMS RPC gas gaps adopted in the CMS upgrade. Quality assurance is enforced in order to maintain the quality of RPC gas gaps at a similar level as for the previous CMS endcap RPC chambers. Both the production procedures and the quality assurance are mature, and effective for the mass production of these RPC gas gaps.
