USA Manufactured Black Cast Iron Pipe Blind 125# Flange

USA Manufactured Black Cast Iron Pipe Blind 125# Flange

USA Manufactured Black Cast Iron Pipe Blind 125# Flanges provide a durable and serviceable method for closing the end of a flanged pipeline, valve connection, vessel nozzle, or industrial equipment port. Manufactured in the United States from quality black cast iron, these solid flanges contain no center opening and are designed to bolt directly to a compatible 125-pound-class flange.

A blind flange creates a secure system closure while maintaining convenient access for future inspection, testing, cleaning, maintenance, or piping expansion. Unlike a permanently welded cap, a bolted blind flange can be removed without cutting the pipe or altering surrounding components. Accurately drilled bolt holes support dependable alignment with matching flange patterns.

Durable 125# Solid Flange Closure

Black cast iron provides excellent rigidity, dimensional stability, and resistance to ordinary mechanical wear. USA manufactured black cast iron 125# blind flanges offer consistent dimensions and dependable flange-face alignment for commercial, mechanical, and industrial piping installations.

The 125# designation identifies the flange class and dimensional pattern. It does not necessarily mean the flange is suitable for 125 PSI under every operating condition. Actual allowable pressure depends on flange size, material, temperature, gasket selection, connected components, and applicable system requirements.

A properly selected gasket is installed between the mating flange faces, and compatible bolts and nuts are tightened using the recommended sequence and torque.
