Pro-source 90381400109 Pvc Blind Pipe Flange Sch 80

Product Description

The PRO-SOURCE 90381400109 is a Schedule 80 PVC blind pipe flange designed to seal and terminate a 3/4-inch pipe line. Manufactured in gray PVC, this blind flange closes off a flanged pipe end completely, blocking flow or pressure without the need for a threaded cap or plug. Its 3-7/8-inch outer diameter suits standard flange bolt patterns. The Schedule 80 wall rating means it handles higher pressure demands than Schedule 40 components, making it appropriate for industrial and commercial plumbing systems. Plumbers and pipefitters install this fitting where a pipeline must be capped at a flanged connection point for maintenance, system isolation, or future expansion access.

This blind flange is suited for use in commercial and industrial PVC piping systems where a flanged pipe terminus must be sealed. Typical applications include chemical handling lines, irrigation manifolds, water treatment systems, and process piping where PVC is specified for corrosion resistance. The gray Schedule 80 construction aligns with common industrial piping standards. It installs against a mating flange face and is secured with bolts through the standard bolt-circle pattern for this pipe size, providing a reliable, pressure-rated closure at the pipe end.

Key Features

• Schedule 80 PVC construction provides greater wall thickness and higher pressure rating than Schedule 40
• Blind design completely seals a flanged pipe end with no through-bore
• Fits 3/4-inch nominal pipe size with a 3-7/8-inch outer diameter
• Gray PVC material resists corrosion and chemical degradation in wet and process environments
• Flat flange face mates with standard flanged fittings and valves for a secure bolted closure

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 80 PVC flanged piping systems using 3/4-inch nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing code requirements. Depressurize and drain the line completely before removing any existing flange or fitting. Use appropriate flange gaskets and evenly torque bolts in a cross pattern to ensure a leak-free seal. PVC flanges should not be overtightened, as the material can crack under excessive bolt load.
