SINGLE SPHERE EXPANSION RUBBER JOINT

Single Sphere Expansion Rubber Joint Product Information

Single sphere expansion rubber 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. Our 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. Wei can manufacture and supply the single sphere expansion rubber joint according to the standard ANSI, JIS, DIN, BS with sizes of 1-1/4″~120″ (DN32~DN3000mm).
