MS fittings commonly come in the shapes of elbows, tees, couplings, reducers, unions, and caps. MS fittings are excellent for a variety of non-critical applications since they have good strength and endurance. They are readily accessible, affordable, and come in a variety of shapes and sizes. For MS pipe systems to have connections that are dependable and leak-free, proper installation and maintenance are crucial.
