Class 75 Carbon Steel Tube Angle Ring Flanges

Steel Tube · Angle Ring · Class 75 · 20 parts

This line of carbon steel Marzolf flanges is designed to fit OD tube angle face rings. They are thicker than our class 75 rings. The Marzolf two-piece design allows you to simply remove the broken rings and replace them without cutting and rewelding the pipe. The interleaving component is engineered to provide uniform preload to assure a consistent and effective seal. Our carbon steel rings are available with electro-zinc plate or E-coat epoxy coating to enhance corrosion resistance.
