Series 575 Electrofusion Tapping Saddle with CC Thread
The transition fitting consists of a two-piece construction. The electrofusion branch saddle and the fitting are joined together by hydraulically pressing the fitting into the HDPE electrofusion branch saddle and reinforcing it with a steel compression ring. The steel fitting portion of the transition fitting is machined with a multi-level barb system that provides a leak-free radial compressed joint. The low-profile, heavy-duty design allows the corporation stop a secure connection to the outside wall of the HDPE pipe.
Relaxation of the pipe creates a seal to prevent leakage. Under pressure, the internal pressure within the pipe increases the sealing surface area on the barb. Under zero internal pressure, the compression and tensional strain created by the compression of the multi-level barbs are greater than the stress created by relaxation and/or thermal expansion and contraction. As the internal pressure increases, the connection between the pipe material and transition fitting increases.
- Sizes range from 0.75” to 2” CC/AWWA threads made to AWWA C800.
