Rubber expansion joint with single sphere and flange connection. Body made of EPDM elastomer, with flanges of galvanised carbon steel in accordance with standard EN-1092 (PN10/16/25/40), circular steel cable, polyamide 6 inner fabric. The expansion joint is a connection suitable for pipes and rigid systems to protect the installation and components against electrolysis, vibrations, expansion and contraction, water hammer and to reduce noise. Model 5121 withstands a nominal working pressure of 16 bar (250 psi) and a burst pressure of 30 bar. It has an operating temperature of -20 to 120°C and a working vacuum of 0.56 bar. The expansion joint is ideal for application in pumping, heating and air conditioning (HVAC) systems, air compressor equipment, cold water and hot water, compressed air and compatible chemicals. MT Industrial Division products are high-quality parts, specifically designed for industrial contexts. The entire range is manufactured under strict quality parameters and complies with the highest certifications in fluid handling.
