Frequently asked questions

Find answers to common questions about our products and services
  • MNPT stands for Male National Pipe Thread, meaning this fitting has external threads on the threaded end that screw directly into a female NPT-threaded port — such as an outlet or inlet on a fluid storage tank or dispensing unit.

  • The 90-degree angle redirects the attached hose at a right angle relative to the threaded port. This is useful when hose routing must go sideways or downward from the tank connection rather than straight out, helping avoid kinks or clearance issues in tight installations.

  • The 1-inch designation refers to the MNPT thread connection. The compatible hose inner diameter for the barb end is not separately specified — confirm the matching hose size with Fluidall before ordering to ensure a proper fit.
