Protection for housing or pipe interiors - uses stopper made from elastic material pressed into pipe end and with flexible sealing lips

摘要

For protecting the interior space of pipes or housings, a stopper is produced from an elastic material which can be pressed into the pipe end. The outer circumference of the stopper hermetically seals the inner covering of the pipe to be protected (1) or a housing. It alternatively adjoins the interior surface of any protective cap being used (4). The stopper is made in the form of a cylinder closed off on one side and is fitted on it's outer covering with flexible sealing lips which enclose it's circumference.
