<p>A cleaning plug for cleaning and preventing contamination from entering the interior of a piece of tubing. The cleaning plug is compressible such that it may be compressed to a size smaller than the interior of the tubing and inserted into the tubing without abrading or otherwise leaving contamination on the interior walls of the tubing. The cleaning plug is then allowed to expand such that it contacts and forms a seal with the interior wall of the tubing. The cleaning plug is made from a material which is nonabrasive, non-contaminating and nonreactive with liquids to be passed through the tubing. When used for preventing contamination from entering the tubing, the cleaning plug is inserted adjacent to the opening of the tubing. When used for cleaning, the cleaning plug is inserted into the tubing and moved longitudinally along the inside of the tubing to mechanically remove any contamination.</p> |
