Seal with lip projections

Seals for mechanical couplings and fittings have sealing surfaces with one or more projections that form closable leak paths between the coupling or fitting and pipe elements being joined. The leak paths close when the coupling or fitting is properly installed. Otherwise, the leak paths remain open...

More Information
Summary:Seals for mechanical couplings and fittings have sealing surfaces with one or more projections that form closable leak paths between the coupling or fitting and pipe elements being joined. The leak paths close when the coupling or fitting is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings and fittings can be discovered during pressure testingand before service pressure is applied. 用于机械联接件和配件的密封件具有带个或多个凸起的密封表面，凸起形成连结的联接件或配件与管元件之间的可闭合的密封通路。泄漏通路在联接件或配件正确安装时闭合。否则，泄漏通路保持开启，以确保可在压力测试期间和施加工作压力之前发现不当安装的联接件和配件。
