Series 740 The Hose Barb Transition
The Poly-Cam hose barb transition is a multi-level mechanical transition fitting. The polyethylene or pipe-quality copolymer material are hydraulically compressed into the transition fitting.
The external barbs allows for the installation of a hose connection that slides over the barbs and is secured with a band clamp.
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 10” Iron Pipe Sizes.
