3. Flange (Series ULSS & ULSM): If installing on a flange, select a flange with a thread that is above the
plane of the flange, such as the ULS‐ACC‐312.
a. The Series ULSL works well with flange installations.
b. Avoid the use of blind flanges with tapped threads or flanges where the threads are even with
the plane of the flange, such as the Banjo 1" Poly ANSI Flange (series AF100).
c. Use a flange with a 2” thread and add a 2” to 1” reducer bushing to complete the installation.
