Grainger 900W Motion Industries- ask for Mark Pneumatrek- as for Brad NAPA, AutoZone, etc. Applied Tech Hose & Rubber on 300 West, ask for Scott Air Products off 3300S around 7th West McMaster-Carr (mail order) Hose Products on 300W If one of the above doesn't have it, it's not made. You can also buy an O-RING KIT where you can make them any size you want. -Barrett -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Patrick Wiggins Sent: Saturday, December 17, 2011 5:18 AM To: utah astronomy listserve utah astronomy Subject: [Utah-astronomy] Seeking O-ring for finder / Need memory? Could someone point me to a good local source of O-rings? I need one for my finder scope. No luck at Home Depot. Specifically I need something with an outside diameter of 50mm and an inside diameter of 43mm. Also, I recently had the memory in my iMac increased and now I find myself with two 2GB sticks left over. Any interest?
