我们是军用标准 M8791/1 系列支撑环等军用规格部件的首选供应商。
这些保持器、填料支撑环符合 SAE-AS8791 规格。它们是单圈的，也被称为Scarf-cut。
我们提供多种规格的M8791支撑环。你会发现宽度在0.052到0.236英寸之间，内径在0.108到5.997英寸之间，外径在0.16到6.233英寸之间。可从0.05至0.12英寸的厚度中选择。对于M8791系列中较大的填料挡圈，我们推荐使用MS27595未切割的填料挡圈。选择一个单独的支撑环型号以查看其变化。
支承环（填料挡圈）是用于将弹性体密封（通常是O型圈）固定在适当位置的刚性环。使用支撑环可以防止O型圈密封系统的挤压。我们的支撑环的制造符合或超过美国的军事标准。
注：SAE-AS8791取代了AS8791和AS8791/1，后者取代了MIL-R-8791和MIL-R-8791/1。
