A sealed assembly, includes a telecommunications enclosure having an inner rim with an upwardly facing tilted surface. The tilted surface of the enclosure has a tilt angle between about 30 degrees and about 60 degrees, preferably about 45 degrees. At least one, and preferably two, o-rings are provided. An end cap is shaped to fit the enclosure. The end cap has a groove. The groove has at least two sides for holding the o-ring in a position to contact the tilted surface of the rim, so that the o-ring is compressed between at least three surfaces when the end cap is in place on the enclosure. This construction forms a high-pressure seal between the rim and the end cap. The groove may include a curved surface for trapping the o-ring. Alternatively, the groove may include three flat surfaces instead of a flat surface and a curved surface.
