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. MS21919WCH8's are silicone cushioned loop clamps, 1/2" in diameter and made of corrosion resistant steel (CRES). These clamps are designed to easily encapsulate tubes or wires. With two round holes at each end, these clamps are closed with a bolt during assembly so that a proper closing is furnished to the task at hand.

I work on old vintage motorcycles, most of which have a fair amount of oil and grease on the engine and transmission parts. These gloves are so much better than the run of the mill cheapo's that can be bought about the same price. Yes, these will tear like any nitrile glove, but these are very, very durable and do a very nice job of standing up to gas, oils, and brake cleaner. I've yet to find any better than these for the price. No complaints whatsoever.
I took the chance of ordering expired Loctite 330. It was jelled up pretty good and generally unusable. It was my fault for trying it and never called the company to complain as I took the chance and that is on me. Order the good stuff.
Had used aviation Camguard for years. Added as well to each quart of oil added to my Lyc 540 SIA5 aerostar engines. Went past TBO with excellent compressions. Oil analysis always normal.
Also add to automobiles but too early to see a benefit.
