SharkBite® tubing is a cross-linked polyethylene tubing used for potable water application. SharkBite® tubing is manufactured without an oxygen barrier. The tubing is printed with a SharkBite® imprint pattern that provides a visual aid to determine if the tube has been inserted all the way into the SharkBite® push-fit fitting. This feature only works if the tubing is cut between the SharkBite® imprint pattern.
