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 closure 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 leaded red brass product with NPT ASTM requirements.
Why Choose a Brass Blind Flange?
Removable Line Closure
- Closes the end of a compatible flanged system
- No center bore for flow
- Provides a bolted and removable closure
- Useful for isolation and maintenance access
- Suitable for future system expansion points
Domestic Red Brass Construction
- Domestic product
- Leaded red brass construction
- Suitable for compatible commercial and industrial piping applications
- Manufacturer dimensional documentation available
- Manufacturer certification documentation available
Blind Flange vs. 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
