Series 810 Gas Transition with Male NPT
The Poly-Cam Threaded Transition is a multi-level mechanical transition fitting. The polyethylene or pipe-quality copolymer material are hydraulically compressed into the transition fitting.
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. A stainless-steel insert is installed to reinforce the connection between the polyethylene pipe and fitting. This design meets ASTM D 2513 Category 1. The fitting is not designed as service riser or anodeless riser application for natural gas services.
- Sizes range from .5 to 12” NPT.
- All National Pipe Threads are made to ANSI/ASME B1.20-1983 R 1992.
