Pro-source 90381400309 Pvc Blind Pipe Flange Sch 80

Product Description

The PRO-SOURCE 90381400309 is a Schedule 80 PVC blind pipe flange designed to seal off the end of a pipe run. It fits 1-1/4 inch pipe and measures 4-5/8 inches in outer diameter. Constructed from gray PVC, this flange provides a durable, corrosion-resistant closure for pressurized or non-pressurized piping systems. Blind flanges are used when a pipe end must be capped off at a flanged connection point rather than threaded or solvent-welded. The Schedule 80 wall rating makes it suitable for moderate-pressure applications in industrial, commercial, and plumbing environments. Plumbers and pipefitters install this fitting wherever a permanent or semi-permanent blanking solution is needed at a flanged joint.

This blind flange is suited for use in water distribution, chemical handling, and industrial process piping that uses Schedule 80 PVC flange systems. It is appropriate for residential and commercial plumbing applications where a flanged pipe terminus must be closed. The 1-1/4 inch pipe size fits standard piping in that nominal size range. The gray PVC construction is the industry standard color for Schedule 80 pressure-rated PVC fittings, making it easy to identify in the field.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system completely before removing any existing flange or installing this blind flange. Bolt holes should be aligned evenly and fasteners tightened in a cross pattern to ensure an even gasket seat and leak-free closure. Consult applicable IPC or local plumbing code requirements for gasket material, bolt specifications, and pressure ratings before installing in pressurized service.
