2-1/2 Inch Flanged Double Sphere Rubber Expansion Joint PN10 PN16 ANSI 150

Product Overview:

The 2-1/2 inch (DN65) Double Sphere Rubber Expansion Joint is engineered to absorb thermal movements, vibrations, and misalignments in piping systems. With dual spherical arches, this joint offers superior flexibility and pressure absorption compared to single sphere models. It is equipped with flanged ends that comply with PN10, PN16, and ANSI 150 standards, ensuring easy integration across international pipelines.
