This is a misleading product. National O-Ring was original manufacturer of the OK-311 kit, however, it stopped manufacturing the kits since 2003.Even if was an old stock, NBR (nitrile O-rings) have shelf-life of 15years, which will be then way past-due.This is another company using the National O-Ring - a well recognized name - to sell their products.I cannot judge the quality of the parts, however, I can tell these are not ORIGINAL National O-Ring products.
