Pro-source 853-080 Pvc Blind Pipe Flange Sch 80 8 Inch

Product Description

The PRO-SOURCE 853-080 is a Schedule 80 PVC blind pipe flange designed to seal the end of an 8-inch pipe system. Blind flanges close off a piping run without requiring a threaded or welded cap, making them useful for pressure testing, future tie-in points, or permanent line termination. This flange measures 8 inches pipe size with a 13.5-inch outer diameter and is molded from gray PVC, consistent with Schedule 80 construction standards. At 6.74 pounds, it is a solid, full-face blind flange suitable for demanding non-metallic piping applications. Licensed plumbers and pipefitters are the typical installers.

This blind flange is suited for use in residential and commercial plumbing, industrial process piping, chemical handling, and water treatment systems where PVC is the specified material. Schedule 80 flanges are chosen when higher pressure ratings and wall thickness are required compared to Schedule 40. The gray PVC construction resists corrosion and many common chemicals, making it appropriate for applications where metal flanges would be unsuitable. It fits standard 8-inch PVC piping systems and mates with corresponding Schedule 80 flanged fittings or stub-end assemblies.

Key Features

• Blind flange design fully closes off 8-inch pipe ends for testing or permanent termination
• Schedule 80 PVC construction provides greater wall thickness and pressure capability than Schedule 40
• Gray PVC material offers corrosion resistance and compatibility with many industrial chemicals
• 13.5-inch outer diameter conforms to standard 8-inch flange bolt circle dimensions
• Lightweight at 6.74 pounds compared to equivalent metal flanges

Compatibility

Designed as an OEM-style replacement and standard fitment for 8-inch Schedule 80 PVC piping systems using flanged connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASTM standards for PVC pressure piping. Depressurize and drain the line completely before removing any existing flange or fitting. Use the correct bolt pattern, gasket material, and torque sequence per the flange standard - do not over-tighten fasteners as PVC flanges can crack under excessive load. Solvent cement, if used on associated fittings, must cure fully before the system is pressurized.
