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.
