Asc Engineered Solutions 308017805 Blind Flange 12 in Class 125

Product Description

The ASC ENGINEERED SOLUTIONS 308017805 is a Class 125 cast iron blind flange designed to seal the end of a pipe, valve, or pressure vessel opening. Blind flanges provide a solid, removable closure that allows future access to a piping system without cutting or welding. This unit carries a 12-inch fitting size with a 19-inch outer diameter and weighs 88 pounds, making it a heavy-duty component suited for industrial and commercial plumbing, waterworks, and process piping installations. It ships with a black coating applied over the cast iron body for basic corrosion protection during storage and installation.

This blind flange is intended for use in low-pressure piping systems rated to Class 125 service. Typical applications include municipal water distribution, fire protection mains, industrial process lines, and HVAC hydronic systems where a flanged terminus is required. Plumbers, pipefitters, and mechanical contractors install this component when a bolted, gasketed end closure is specified by the system design or local code.

Key Features

• Class 125 pressure rating for low-pressure piping service
• 12-inch fitting size with a 19-inch outer diameter for standard bolt-circle alignment
• Cast iron construction provides durability in water and process piping environments
• Black coating applied for corrosion protection during handling and storage
• Domestically manufactured
• Solid blind face allows system access when unbolted without pipe modification

Compatibility

Designed as an OEM-style replacement or new-installation component for Class 125 cast iron flanged piping systems with a 12-inch nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as ASME B16.1 and local jurisdiction requirements. Depressurize and isolate the piping system completely before removing or installing any flanged component. A full-face gasket appropriate for Class 125 iron flanges should be used, and bolts should be tightened in a cross pattern to ensure even seating. At 88 pounds, mechanical lifting assistance or a second person is recommended when positioning this flange.
