DOUBLE SPHAERE RUBBER EXPANSION JOINT

Double Sphere Rubber Expansion Joint Product Information

Double sphere rubber expansion joint is also known as shock absorber, pipe shock absorber, shock proof box and soft joint. It is a pipe joint of high-flexibility, high-gas tightness, resistance to medium and climate. Rubber expansion joints has five types: single sphere rubber expansion joints, double sphere rubber expansion joints, threaded rubber expansion joints, reduced rubber expansion joints and rubber bending joint. There are two kinds of connections: flange and threaded. The rubber expansion joints is widely used in water supply and drainage, recycled water, air conditioning and heating, fire control, shipping, water pump, and compressor, Etc. We can manufacture and supply the double sphere rubber expansion joint according to standard of ANSI, JIS, DIN, BS with sizes of 1-1/2”~24” (DN40~DN600mm).
