Product description
Single Arch Rubber Joint
Single arch rubber joints, also known as single sphere rubber joints,
are designed for piping systems to absorb pipe movements, relieve
stress, reduce system noise/vibration, compensate for
misalignment/offset and to protect rotating mechanical equipment against
start-up surge forces.
Features and Benefits
·Absorbs directional movement
·Absorbs vibration, noise and shock
·Compensates for misalignment
·Wide flowing arch design
·Economical fully molded construction
·Special grooved flange ring design, prevent rubber end pulling out
·Solid galvanized steel floating flanges speed the installation time
·No gaskets required; integrally rubber flanged design
