Pro-source 90381400209 Pvc Blind Pipe Flange Sch 80

Product Description

The PRO-SOURCE 90381400209 is a Schedule 80 PVC blind pipe flange rated for 1 inch pipe with a 4.25 inch outer diameter. A blind flange closes off the end of a piping run, capping pressure lines or serving as a service access point where future system expansion may be needed. Made from gray PVC, this flange suits corrosive-fluid and chemical-handling applications where metal flanges are not appropriate. Licensed plumbers and pipefitters install blind flanges as part of pressure-tested piping assemblies. At 0.45 pounds, it is lightweight and easy to handle during installation in tight spaces.

This blind flange is suited for residential and commercial PVC piping systems where a pipe end must be sealed. Typical applications include water treatment lines, chemical distribution systems, irrigation headers, and drain-waste-vent assemblies where a capped terminus is required. Schedule 80 construction provides thicker walls compared to Schedule 40, making this flange appropriate for higher-pressure service lines. It is most commonly installed in horizontal or vertical runs where a permanent or serviceable cap is needed at a branch or main line termination.

Key Features

• Schedule 80 PVC construction offers greater wall thickness and pressure rating than Schedule 40
• Blind style seals the end of a piping run for pressure containment or future expansion access
• Gray PVC resists corrosion, making it suitable for chemical and water treatment service
• 1 inch pipe size with 4.25 inch outer diameter fits standard Schedule 80 flange connections
• Lightweight at 0.45 pounds for easy single-handed positioning during installation

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 80 PVC piping systems using 1 inch nominal pipe size flanged connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Depressurize and drain the piping system fully before removing any existing flange or installing this component. PVC flanges are typically solvent-cemented or bolted depending on the flange face style; use only PVC-compatible solvent cement and hardware rated for the service pressure. Do not overtighten flange bolts, as PVC is subject to cracking under excessive torque.
