Polyethylene Tank

The 2ND STEP is to select the quantity and size of connections required for your tank. Please note that because of how our site functions, if you have multiple tanks of varying diameters, you will want to repeat steps 1 - 3 to select the fittings for each tank diameter.

These heavy duty radiused tank adapters are designed to provide a long term solution to large fitting requirements and include everything necessary for installation. The mounting saddle on these high performance fittings is radiused to match the curvature of your tank, providing for an unmatched sealing capability. Fittings are also available for mounting on flats and curved domes. All fittings can be made for small diameter tanks; just let us know your fitting size and tank diameter.
