What is an expansion joint 3 inch?
Pipework needs parts that move, show and measure. Rubber expansion joints absorb vibration and movement at pumps, sight glasses show flow, meters measure water, and pumps such as diaphragm and sewage pumps move difficult fluids.
Each part must suit the pressure and fluid. Therefore, confirm size, rating and material with your quote.
