Abstract

PURPOSE:To prevent foreign substance mixture into an existing opening port in such a way that a flexible ring-shaped seal material is provided in the formation of being able to expand and contract by being inserted between a fixture and an inserting holder which forcibly press it together. CONSTITUTION:In concurrence of making a seal material 3 by rigging a cleaning cover 3b onto a seal ring 3a with screwedly attaching an inserting holder 2 to the screwed part 1b of a fixture 1, the flexible seal material 3 is inserted between a main body 1a and the inserting holder 2. Then, these are arranged at the fixed spot of an opening port 7 of a piping or the like, the fixture 1 is swiveled. At that time, the inserting holder 2 moves upward and forcibly presses the seal material 3 which expands its outer diameter. This eliminates gaps between the opening port 7 and the seal material, facilitates to have the equipment fixed at this part, and to prevent mixture of foreign substance. Further, installation at a spot beyond reach of hand is done through an adapter8.
