Dresser Couplings Style 38 are also available in cast-iron sizes from 2" to 72". These Couplings have long been used by gas and water com panies for the joining of plain-end cast-iron pipe. Dresser Couplings combine the advantages of abso lutely tight joints and easier, faster joint making. Style 38's also permit the salvage and use of random lengths of cast-iron pipe from which bell-ends or cracked sections have been removed.
Materials of construction are the same as those for Steel Pipe Sizemore
