Dixon 4 in. x 3-1/4 in. TTMA Flanged Short Sight Flow Indicator
Dixon 4 in. TTMA Flanged sight glasses are made of a durable cast aluminum housing with a low cost sight glass tube that can be easily replaced. The sight glass allows for visual identification of the product prior to opening the valve. Larger 4 3/8 in. inside flow indicator allows butterfly valves to be connected to either end. Note: Due to the proprietary blending of petroleum products, Dixon recommends that the thermoplastic tubing and the gaskets be immersion tested in the product to be handled to ensure compatibility.
