Structural offers a new, encapsulated inlet design on an expanded range of residential Poly Glass™ tank sizes. A failsafe universal inlet, currently available on 14 popular tank sizes, is the latest improvement to the vessel line; it is a completely seamless way of connecting the valve to the tank. When the valve is threaded into the sealing surface on the tank, the valve literally seals to the liner, eliminating the potential for leaks. It can seal radially or flat on the liner face. A range of 14 vessels with the inlet is available immediately; additional tank sizes will launch over the course of 2008. http://www.penta.com, (888) 922-8265
