1/4 NPT to 5/16 (8mm) Hose Barb Fitting, Brass - Straight

This straight brass adapter is useful for connecting 5/16" or 8mm ID rubber fuel line to a 1/4 NPT female port on fuel pumps, pressure regulators, carburetors, or Tee fittings. Use with standard worm drive hose clamps. Sold individually.

Note: NPT nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. Male 1/4 NPT threads measure approximately 1/2" OD. For more information, check in our Guide to Using NPT Fittings.
