Raychem Rayflate Adapter RDSS-AD-210 for Large Duct Sizes
The Raychem RDSS-AD-210 adapter is moulded from a specially formulated rubber for easy installation and superior duct sealing. The one-piece, single-sized adapter is designed to work with Raychem Rayflate duct sealing products RDSS-125 and RDSS-150 for sealing ducts up to 210 mm in diameter (see EPP 0569 brochure). The adapter is a simple add-on to existing Raychem RDSS products and requires no additional training or change in installation procedures and practices
Once installed, the duct sealing system ensures that manholes remain clean and dry. This eliminates the need to pump out rain or sewage water from the manholes and provides immediate access for maintenance crews, significantly reducing downtime
Clean, fast, easy, tool-free sealing
After the sealant tape has been lubricated the Raychem adapter RDSS-AD-210 is coiled over the cable to fit the duct. The coiled adapter slides easily into the duct and when released snaps into position against the inner wall of the duct. Then the Raychem RDSS is inserted between the cable and the pre-positioned adapter and inflated in the usual way. Certain configurations may require two adapters. For details check the selection table. The entire installation is performed in a few minutes – even in congested enclosures – without messy and potentially harmful mixing and filling agents.
Versatility
The special type of rubber adapts to most configurations. The standard size covers a large range of cable and duct diameters.
Performance tested
Extensive testing with various duct sizes at room temperature and under load cycling conditions has shown that the sealing system is watertight and airtight at specific temperatures, even when cables were subjected to bending or vibration. Resistance to common chemicals has been proven by immersion tests. The detailed PPR-1659 test report is available on request.
