Vance, I thought you were joking in your earlier post requesting Parker’s URL. This will take you right to Parker’s O-ring manual and catalog: http://www.parker.com/portal/site/PARKER/menuitem.734d2913eb3c11da13576f849420d1ca/?vgnextoid=d195f87357e28110VgnVCM10000048021dacRCRD&vgnextfmt=default&division=b126981ef31a0110VgnVCM10000048021dacRCRD&literaturetype=Catalogs&searchAttr=searchResult&languages=EN&parentCh=Division#results Review of their software finds that it will only run on Win XP or earlier PCs. R/Jay Resepectfully, Jay K. Jeffries Andros Is., Bahamas Save the whales, collect the whole set. From: owner-personal_submersibles@psubs.org [mailto:owner-personal_submersibles@psubs.org] On Behalf Of vbra676539@aol.com Jay, Was that you who posted the Parker address for the O-ring tutorial? Could you do it again? I seem to have misplaced mine. Vance |
