ELBOW ASSEMBLY for Resmed MIRAGE FX Cpap Bipap Nasal Mask 62112 - New 

Either eBay or Resmed, I'm not sure which, will not allow sellers to sell entire sets of factory-sealed components.  The parts have to be broken up and sold separately.  This elbow assembly is one such part.  I put on surgical gloves, make a small cut in the larger packaging and slip out this piece, transferring it to a new zip-lock bag.  If you are unsure if that is clean enough, simply run it under some hot water before using.  If that doesn't satisfy your need for sanitation, please don't buy this product.
