The construction of the connector utilizes molded convolutions of white PTFE. These convolutions are reinforced with metallic rings between the bellows for pressure rating and stability. The metal backing flanges are protected by the lip of the Teflon bellows, so that all wetted surfaces are Teflon. Steel limit rods are factory installed. Additional convolutions provide greater movement capability. Options include Type 316 stainless steel backing flanges and hardware, white epoxy coated flanges, and high-purity cleaning and packaging. 700 series expansion joints can also be manufactured in a machined, accordion style, ideal for plastic piping systems.
