The Posi-Flange advantage is its strength. A compression seal is accomplished by stainless steel nuts and bolts. This is very desirable when a valve or pump is mounted on immediate piping. The Posi-Flange provides a female thread fitting. No metal is exposed to solution.
PVC fittings are available in sizes 1⁄2" through 6". Teflon® fittings provide excellent corrosion resistance. Teflon® sizes are: 3⁄4", 1", 1 1⁄2" and 2".
