Heating, ventilating and air conditioning

he HVAC rubber expansion joints eliminate stresses caused by changes in temperature and piping misalignment, as well as reduce the transmission of noise and vibration. The HVAC rubber expansion joints are used on both hot and chilled water circulation lines, suction and discharge sides of pumps, and header connections. They absorb the continuing movement experienced in piping systems because of varying ambient temperatures, differences in temperature of materials being handled, and differences in composition.
