I have tried to find the thread about o-ring sizes with no luck so I will just take the easier route and ask. I have decided to order from McMaster Carr [never have] and would like to know what their item numbers are for the following o-rings that I use as common bulk items. HP spool 003, 3/8 LP fitting male, second stage end LP hose, and 7/16 HP male. I am also trying to determine a size/number for Dacors 0061, the very thin one used in extreme second stages. I am not sure how to get an accurate measurement on such a small ring . Thanks again for al your help Scott
