These high quality threaded hose barb connectors are used to transition a female tapered thread to a hose, making a simple and clean conversion from threaded connections to hose. Here are some common applications for the various sizes we offer:

• The 1″ Thread x 1-1/8″ Hose Barb version of this fitting is popular boats that use 1-1/8″ (Malibu and Tige) that need to connect to a threaded 1″ NPT connection.
• The 1″ Thread x 1″ Hose Barb version of this fitting is by far the most popular, and is used most often to connect 1″ hose to a threaded 1″ ball valve to feed water into a reversible pump based ballast system.
• The 3/4″ Thread x 1″ Hose version of this fitting allows for the connection of 1″ ballast hose to a 3/4″ threaded connection. This is most often used to adapt an existing 3/4″ threaded connection for use with 1″ hose.
• The 3/4″ Thread x 3/4″ Hose version of this fitting is most often used to connect 3/4″ wakeboard ballast hose to a 3/4″ threaded fitting. The most common application is for connecting Jabsco Ballast Puppy pumps to a bronze ball valve in the bilge of the boat using 3/4″ hose.

• The 1/2″ Thread x 3/4″ Hose version of this fitting is most often used to connect the 1/2″ NPT internal threads on the pump head to a 3/4″ hose connection. Each pump will require two fittings, along with two hose clamps (not included) to make both connections.

  NOTE: We always recommend using 1″ hose with reversible pumps, but if you must use 3/4″ hose, these are the fittings you’ll need.
