NATIONAL油封制造基地从刚创立时的San Francisco， 至1942年搬到Redwood City，再后搬至Summerton和Mexico City，现已把制造重心放在了MEXICO CITY。这就是为什么油封上会标注为USA和MX的缘故。除此两处之外，NATIONAL油封再也没有其它的制造基地了。
而NATIONAL油封与其它品牌的不同之处，就是在铁壳外圈的外径上喷涂了红色的REDICOAT专用涂漆，一方面可以区别其它品牌的颜色，另一方面，也是主要的方面，铁壳外径喷涂红漆可增加外径的密封性能，可填充装配孔腔表面之缺陷或刮痕，避免密封流体由外径泄漏。这种REDICOAT涂漆，对孔腔面的加工光洁度就有所放松，允许有较大的表面粗糙度，同样起到内骨架油封(外径包有橡胶)的密封效果。
