Turn-over seal |
摘要 |
A ring seal for protecting a designated area from ambient contamination is alternately placeable into its sealing and non-sealing positions. The ring seal permits a limited travel between the sealable surfaces without compromising the seal integrity. The ring seal facilitates an interference-free installation and selective maintenance of the sealable parts.
