ABSTRACT:
An open ended cap for a pipe is provided comprising a flexible tubular body wherein one end has an inwardly-extending radial rim extending in a plane perpendicular to the longitudinal axis of the tubular body of the end cap. The tubular body may include a finger grip member extending inwardly from an inner periphery of the rim and connected to a tear strip extending across the rim and downwardly along at least a portion of the tubular body. In another embodiment, the tubular body has an interior wall surface having multiple compressible longitudinal fit beads extending from the interior wall surface and spaced about the circumference of the interior wall surface and which are configured to provide contact with the external surface of a pipe upon being inserted into the end cap. Both a tear strip and longitudinal fit beads may also be provided in combination.
