Asc Engineered Solutions 308016401 Blind Flange 3 in 125

Product Description

The ASC Engineered Solutions 308016401 is a 3-inch Class 125 cast iron blind flange designed to seal off the end of a pipe, fitting, or valve in low-to-medium pressure piping systems. The blind configuration means there is no center bore — the face is solid, providing a pressure-rated termination point. With an outer diameter of 7.5 inches and a weight of 7.92 pounds, this flange is built for durability in demanding installations. The black coating provides corrosion resistance for typical service environments. This is a domestically produced fitting suitable for plumbing, water distribution, and industrial piping applications.

This blind flange is used in residential and commercial piping systems where a flanged pipe end must be capped or blanked off temporarily or permanently. Common applications include water mains, process piping, pump systems, and valve isolation points. The Class 125 pressure rating aligns with standard cast iron flanged fittings used throughout municipal, industrial, and mechanical piping installations. It is typically installed by licensed plumbers or pipefitters working on flanged cast iron pipe systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable plumbing codes, including IPC requirements for flanged connections. Shut off and depressurize the piping system fully before removing any existing flange or installing this blind flange. Use the appropriate gasket material rated for the service fluid between the flange faces, and torque bolts evenly in a cross pattern to ensure a uniform seal. Do not over-stress the cast iron flange body during installation.
