ASME B16.5 A105 Blind flanges are the standard solution for sealing the ends of high-pressure piping systems. Forged from high-quality carbon steel, the A105 grade ensures excellent strength and reliability for ambient and higher-temperature service. The 150LBS rating is the most common pressure class for general industrial applications. These solid discs are bolted into place, providing a liquid-tight seal that allows for easy system expansion or maintenance access in refineries and chemical plants.
