Abstract
A sectional gasket 11 includes corner junction members 12, straight junction members 13, and extension members 14. The junction members 12 and 13 each include a recess 19, and the recesses 19 each include axially extending laterally inwardly facing sealing surfaces 20 and 21. The extension members 14 each have a uniform lateral cross-sectional configuration along their entire axial extent. Each extension member 14 includes axially extending, parallel, laterally outwardly facing sealing surfaces 25 and 26. The sealing surfaces 25 and 26 extend continuously and without interruption along the entire axial extent of the extension member 14. The extension members 14 are characterized by the absence of any special tongue and recess at their opposite ends, and the extension members 14 are manufactured and stored in long continuous strips which are cut to the desired length and used in combination with the junction members 12 and 13 by the end user of the gasket 11.
