Flanged vs Threaded Pump Connectors
Flanged and threaded pump connectors solve similar piping problems but are specified for different connection styles and system requirements.
Threaded pump connectors
Threaded connectors are common for smaller lines and systems that use male NPT or threaded union connections.
- Often used on smaller lines
- Common in HVAC and hydronic systems
- Available with carbon steel or stainless ends
Flanged pump connectors
Flanged connectors are used where the system requires bolted flange connections, such as 150# raised face flanges.
- Bolted flange installation
- Useful for larger lines
- Common in mechanical and industrial systems
How to decide
Match the connector to the existing piping specification and confirm line size, pressure class, material, and overall length.
- Existing connection type
- Pressure class
- Maintenance access
