Flange (Loose Ring), Slip PVC Schedule 80 3" (854-030FT)

Blue Monster 76037 1-Step PVC Cement Clear (32OZ)

The 3" PVC Schedule 80 Loose Ring Slip Flange (854-030FT) delivers reliable, high-pressure flanged connections in corrosion-sensitive piping systems where a bolted, disconnectable joint is required. Manufactured from rigid gray PVC conforming to ASTM D1784 Cell Class 12454, this fitting is engineered to handle the chemical exposure, UV resistance demands, and pressure ratings expected in industrial and commercial applications.

The loose ring (van stone) design separates the PVC flange hub from the backing ring, allowing the backing ring to rotate freely for effortless bolt-hole alignment during installation—significantly reducing labor time in multi-flange runs where precise alignment is critical. The slip (socket) end is solvent-welded directly to Schedule 80 PVC pipe, creating a permanent, pressure-rated joint at the pipe connection, while the loose ring face retains the ability to be unbolted and separated for maintenance, inspection, or component replacement without cutting into the pipeline.

Schedule 80 construction provides greater wall thickness and pressure capacity compared to Schedule 40, making this flange suitable for higher-demand process piping, chemical feed lines, and industrial fluid handling applications. The 150 lb. ANSI/ASME B16.5 drilling pattern on the flange face ensures compatibility with standard flanged pumps, valves, tanks, and equipment.

Gray PVC offers broad chemical resistance to acids, bases, salts, and many organic compounds, making this flange a cost-effective alternative to stainless steel or CPVC in non-elevated-temperature service. For high-temperature applications, refer to the CPVC Schedule 80 equivalent.
