Overview
The Proco 240-M EPDM expansion joint is a molded single-sphere rubber connector designed for industrial piping applications including hydraulic, pneumatic, and plumbing systems. This unit features a durable EPDM elastomer core with plated carbon steel flanges and ASA 150T BS (150 lb. rating) drilling. The single-sphere design absorbs axial, lateral, and angular pipe movements while reducing transmitted noise and vibration throughout your system.
