ABSTRACT:
A seal device for sealing between a surface such as a roof and an elongate member such as a pipe projecting through that surface. A one-piece mounting plate has a planar base portion with an access aperture therethrough, and is composed of metallic, non-resilient, manually deformable material. The base portion is located in a face-to-face relation with a mounting surface so that an elongate member projects through the access aperture. The base portion is deformable to conform to the contour of the surface and retain the deformed contour. A rim portion, which is integral with the base portion, extends about the periphery of the access aperture and upstands from the body portion, and that rim portion has a retaining lip spaced outwardly of the base portion and shaped to provide an underlying shoulder. A sealing member overlies the access aperture and has an access passage for receiving the elongate member therein with the sealing member sealingly engaging the elongate member. The sealing member also has a resiliently flexible skirt portion for overlying the rim portion with at least one retaining projection extending beneath the retaining lip for sealingly engaging against the rim portion and thereby releasably connecting the sealing member to the mounting plate. By resiliently distorting the skirt portion, the retaining projection can be fitted beneath and released from beneath the retaining lip to, respectively, connect and disconnect the sealing member and the one-piece mounting plate.
