Blind Flange, PVC Schedule 80 1-1/2" (853-015)

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

The 1-1/2" PVC Schedule 80 Blind Flange (853-015) provides a solid, pressure-rated flanged closure for terminating, blanking off, or isolating the end of a PVC pipeline without a permanent, non-removable cap. Manufactured from rigid gray PVC conforming to ASTM D1784 Cell Class 12454, this fitting is designed for the chemical resistance and pressure service requirements found across industrial, municipal, and commercial piping systems.

Where a solvent-welded cap creates a permanent termination requiring destructive removal to reopen, a blind flange bolts directly to any mating 150 lb. ANSI flange face and can be unbolted and removed at any time without cutting into the pipeline. This makes the 853-015 the preferred termination method for flushing ports, hydrostatic test points, future branch tie-ins, and cleanout locations—wherever a piping system may need to be reopened downstream of its current terminus.

The 150 lb. ANSI/ASME B16.5 bolt pattern provides direct compatibility with the full range of standard PVC slip flanges, threaded flanges, and flanged valves, pumps, and equipment. Schedule 80 construction matches the pressure class of surrounding Schedule 80 pipe and fittings, maintaining a consistent, uninterrupted pressure rating throughout the system.

At 1-1/2", this blind flange is well-suited for branch lines, chemical feed systems, secondary process loops, and smaller pump connections where a flanged termination is required. Gray PVC resists corrosion from acids, bases, salts, and a broad range of industrial fluids, offering a cost-effective alternative to metal flanges in chemically aggressive environments. For elevated-temperature service above 140°F, consult CPVC Schedule 80 equivalents.
