Spears 54211184721 Cpvc Blind Flange 2 in Sch 80/XH

Product Description

The SPEARS 54211184721 is a CPVC blind flange rated for 2-inch nominal pipe in Schedule 80/XH applications. Blind flanges are used to seal the end of a piping run, creating a pressure-tight termination without requiring a threaded or solvent-welded cap. This flange carries a 150 psi pressure rating at 73 degrees F and conforms to a 150 lb flange class. At 0.88 pounds and manufactured domestically from gray CPVC, it is suited for corrosive-fluid and chemical-process piping where metal flanges are not appropriate. Licensed plumbers and pipefitters install this component in industrial, commercial, and process piping systems.

This blind flange is designed for use where a piping leg must be closed off temporarily or permanently within a flanged plastic or plastic-to-metal piping system. It measures 5-31/32 inches outside diameter with a 4-3/4 inch bolt circle and a thickness of 27/32 inch, fitting standard 150 lb flange bolt patterns. Typical installations include chemical processing lines, water treatment systems, and industrial fluid-handling applications where CPVC material resistance to chlorinated and acidic media is required. The part is made in the United States and meets multiple ASTM and ANSI standards.

Key Features

• CPVC construction provides resistance to corrosive fluids and chlorinated water systems
• 150 psi pressure rating at 73 degrees F for reliable service in Schedule 80/XH systems
• 4-3/4 inch bolt circle diameter conforms to 150 lb ANSI flange bolt patterns
• 5-31/32 inch outside diameter with 27/32 inch thickness for full-face flange sealing
• Domestically manufactured and compliant with ASTM F 439, ASTM F 1498, ANSI B16.5, ASTM D 4024, and ASTM D 1784
• Gray color for easy visual identification of CPVC components in mixed piping systems

Compatibility

Designed for joining plastic to metal piping systems in 2-inch nominal Schedule 80/XH flanged configurations using standard 150 lb bolt patterns.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with plastic flanged piping systems. Shut off and depressurize the piping system completely before removing or installing any flange. Use appropriate full-face gaskets and fasteners rated for the flange class and fluid service. Do not overtighten bolts, as CPVC flanges can crack under excessive torque; follow flange bolt tightening procedures consistent with ASTM and manufacturer guidance for plastic flanged joints.
