Group, I get several questions about the words we throw around and sometimes they need a little explaining to some of the new people getting into automotive. The one I get the most is NOS ( New old Stock and New ( Like in brand new ). Be carefull with NOS inventory, especially items that contain seals, rubber or flexable diaphrams. Items like this will dry out over time and will leak or only work for a short time and quit. Example: clutch master cylinders, accumlators, brake master cylinders and clutch slave cylinders. These items may have been on the shelf for 20+ years and the price you pay for someone selling it cheaper to get rid of them won't be worth the trouble of replacing the part for the sake of saving a few dollars. Ask about warranty or replacement time if it's NOS stock. I hear this often about clutch master cylinders and accumulators. The customer say's he just put one in 6 months ago and it's already leaking. More that likley he got a New old stock. ( NOS ) not brand new fresh inventory. My point is just be carefull about the word ( NEW ) being used and the company should say (NOS ). Normally metal parts that are NOS are good if they have no rust. Remember,parts are ( not ) stored in climate control warehouses and the heat and cold over years will take it's tole. So, Before you buy you may want to find out is it Brand new like in the last year or so or is't it NOS like old inventory.
