Pro-source 90381400709 Pvc Blind Pipe Flange 3 Inch Sch 80

Product Description

The PRO-SOURCE 90381400709 is a Schedule 80 PVC blind pipe flange designed to seal off the end of a 3-inch pipe system. Blind flanges provide a removable closure at pipe terminations, allowing future access to the line without cutting or permanent modification. Molded in gray PVC, this flange delivers corrosion resistance suitable for chemical, water, and drainage service. The Schedule 80 wall rating means the flange meets heavier-duty pressure and mechanical requirements compared to Schedule 40. It is installed by licensed plumbers and pipefitters working on industrial, commercial, or process piping systems.

This blind flange is suited for use in PVC pipe systems where a bolted, removable end closure is required. Typical applications include water treatment, chemical processing, irrigation manifolds, and commercial plumbing lines. The 3-inch pipe size and 7.625-inch outer diameter make it a standard fit for Schedule 80 piping assemblies in both above-ground and indoor-protected installations where UV exposure is limited.

Key Features

• Schedule 80 PVC construction for higher pressure and mechanical load ratings compared to Schedule 40
• Blind flange style seals pipe ends completely while allowing future reopening of the line
• Gray PVC material provides corrosion resistance in chemical and water service environments
• 3-inch pipe size with 7.625-inch outer diameter for standard Schedule 80 flange bolt patterns
• Sold individually, making it practical for single-point repairs or new construction tie-ins

Compatibility

Designed as an OEM-style replacement and new-installation fitting for Schedule 80 PVC pipe systems with a 3-inch nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and ASTM standards for PVC pressure piping. Depressurize and drain the line completely before removing or installing any flange fitting. Bolt torque should follow the flange gasket and fitting manufacturer guidelines to avoid cracking the PVC flange face. PVC blind flanges are not rated for outdoor UV exposure unless specifically listed as such — consult applicable code for burial or exposed-location requirements.
