Military Standard MS20813-1 Yellow Cap, Valve - 5/Pack

Ever wondered what the MS refers to in many parts numbers? SkyGeek does and because we are geeks, it's in our nature to find out. It stands for Military Standard, which means the part has been both tested and certified by US Armed Forces and has met or exceeded such standards. Pretty cool, huh? If the military approves then so do we and so will you. MS20813's are high pressure brass valve caps that are actuated specifically for pneumatic applications. In addition, these caps have a permanent, non-flaking yellow lacquer finish.
