Anvil International Introduces New Flush Gap™ Gasket

New Flush Gap Gasket(Portsmouth, NH) June 11, 2009 – Anvil International, the world’s largest fitting manufacturer, introduces an enhanced sealing Flush Gap™ gasket, the Company announced today. The gasket, which is Patent Pending, is specifically designed for applications where low-temperature performance is needed. Anvil International is a subsidiary of Mueller Water Products, Inc. (NYSE: MWA).
The new gasket is available in a variety of sizes ranging from 1 inch to 8 inches. It contains a center rib which fits flush over the gap between the pipe ends and closes off the gasket cavity. This allows for the reduction of build up of moisture and ice which can cause standard gasket designs to leak under freezing conditions.
The Flush Gap™ gasket also features triple sealing ribs on each gasket seal face, which enhance seal ability under less than ideal pipe surfaces. When combined with the Gruvlok Xtreme™ Lubricant, which eliminates water wash out and which does not dry out like standard product lubricants, the Flush Gap™ with triple seal ribs provides the best gasket seal for grooved couplings in extreme temperature applications.
