How to Choose a Flexible Metal Pump Connector

Choosing the right flexible metal pump connector starts with the application, connection type, material, and overall length.

Start with the application

Identify whether the connector will be used for HVAC, hydronic, industrial, boiler, chiller, or general pump piping service.

  • Pump suction or discharge
  • Mechanical room or industrial system
  • Replacement or new installation

Confirm end connections

The most common choices are threaded male NPT, threaded union, and 150# raised face flange configurations.

  • MNPT x MNPT
  • Male NPT x female union
  • 150# RF flange x 150# RF flange

Confirm material and length

Specify fitting material, hose construction, overall length, and any project documentation requirements before ordering.

  • Carbon steel or stainless steel ends
  • Overall length
  • Compliance or documentation needs
