Orion Fittings, Inc., a manufacturer of acid waste and high-purity piping systems, has redesigned its Style 8 neutralization tank. The clean-out cap, formerly located on the side of the tank, has been relocated to the top, providing easier access for maintenance. In addition, Orion designers have increased the capacity of the tank by nearly 100% over the previous Style 8 design. Rotationally molded from tough, high-density polyethylene, the tank is available in Orion's signature blue color. Orion Fittings, Inc. Circle 18.
