Blind Flange Construction
A blind flange is a solid flange without a center opening. It bolts to a compatible mating flange and gasket to close the piping system at that location.
Because the connection is bolted rather than permanently sealed, the blind flange can be removed later for inspection, maintenance, cleaning, equipment access, or future piping expansion.
The supplied product information identifies this flange as a domestic lead-free brass product with a 150 lb flange pattern and NPT ASTM requirements.

Removable Line Closure
- Closes the end of a compatible flanged system
- Solid construction with no center bore
- Provides a bolted and removable closure
- Useful for isolation and maintenance access
- Suitable for future system expansion points
Lead-Free Domestic Brass
- Lead-free brass construction
- Domestic product
- 150 lb flange pattern
- Suitable for compatible applications requiring lead-free brass
- Manufacturer certification documentation available
Blind Flange vs. Threaded Companion Flange
Blind Flange
- Solid flange with no center bore
- Designed to stop flow and close a connection
- Bolts to a compatible mating flange
- Useful for line termination and isolation
- Can be removed for future access
Threaded Companion Flange
- Includes a threaded center bore
- Connects threaded pipe to a flanged component
- Allows flow through the flange
- Used as a piping connection rather than a closure
- Different function from a blind flange
Common Applications
Commercial & General Piping
- End-of-line closures
- Mechanical piping systems
- Utility piping systems
- Valve isolation points
- Equipment connections
Service & Maintenance Applications
- Temporary piping closures
- Permanent line terminations
- Inspection access points
- Future expansion connections
- Serviceable flanged assemblies
Lead-Free Material
The supplied product information identifies this flange as lead-free brass. This makes it appropriate for applications that specifically require a lead-free brass flange, subject to the requirements of the piping system, governing codes, and manufacturer certification.
Review the manufacturer certification letter below for applicable product and compliance documentation.
Installation & Selection Guidance
- Confirm the required nominal flange size before ordering.
- Verify that a 150# flange pattern is required for the application.
- Confirm flange dimensions and bolt pattern compatibility with the mating flange or equipment connection.
- Select an appropriate gasket for the mating flange configuration and service conditions.
- Inspect both flange faces before installation.
- Use the correct bolt size and quantity for the flange pattern.
- Tighten flange bolts in an appropriate sequence to promote even gasket compression.
- Verify pressure, temperature, and media compatibility before installation.
- Confirm that the lead-free material specification meets the requirements of the intended application.
- Installation should comply with applicable piping codes and project requirements.
