The hot tub pump drain plug barbed hose adaptor fits Waterway, Balboa and Aqua-Flo brand hot tub pump wet ends to attached a 3/8" clear house to the face. Some manufacturers glue the fittings into place so they cannot be transferred when replacing the pump. If this is the case, purchase new barb fitting(s) as required for the configuration of your spa.



  • Waterway part number 672-4350
  • Barb Fitting, 3/8in. Barb x 1/4in. Mpt.
  • 1 or 2 barb fittings per pump are sometimes used by hot tub manufacturers in place of pump drain plugs.
  • Does not include o-ring. Use the o-ring from the new drain plug you are replacing, or purchase separately. Part # 805-0112
  • Can be white or black
  • Made in the USA by Waterway Plastics


Do not to over-tighten, barb fittings will break off at the threads if too much force is applied as the material is softer than what the wet end is made of.
