Single Sphere Rubber Expansion Joint

Introduction of rubber expansion joint

Single Sphere Rubber Expansion 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.

The molded single sphere and twin sphere designed bellows are inherently stronger than the conventional hand-built style spool arch type.

Internal pressure within a “sphere” is exerted in all directions, distributing forces evenly over a larger area. The spherical design “flowing arch” reduces turbulence

and sediment buildup.
