Abstract
An entry fitting having a cylindrical portion and a conical portion including a seal disposed about the body of the entry fitting. An axial displacement member urges the seal along the conical portion to achieve a relatively wide range of sealing force. The entry fitting can include a shield positioned on the exterior of a sump to provide an access space for displacement of the entry fitting toward the exterior of the sump to allow removal and replacement of the seal without first having to remove backfill from the exterior of the sump.
