EPDM expansion joints help to relieve heat, extension and contraction stresses in pipe or pipe installations. EPDM rubber expansion joints can withstand temperatures up to 110-130 ° C and diluted alkalis and acids. The rubber EPDM expansion joint is resistant to UV rays and weathering and is suitable for outdoor applications.

Since the EPDM rubber expansion joint absorbs the elongation and contraction of the pipe caused by temperature changes, it can prevent damage to the piping system and equipment.
