Powerful spa ozone generators like the ORIGINAL MCD-50 and MCD-250 are known to disintegrate the hose barbs on the ozonators where the ozone tubing comes out.  Although improvements have been made to help prevent hose barb breakage, there are a lot of spa ozone generators with broken barbs - we're here to help.

This black 7-1025 Hose Barb is also be used on the Big Dipper Above-Ground Pool Ozonators.  If your Big Dipper has a blue hose barb, this is the same form, fit and function.

A broken hose barb could be a sign ozone is not properly getting sucked out of the generator and into the water.  When the system is on (filtration on, ozone on), ozone should be pulled away from the ozonator, and water should be going forward, not backward.

Do you have a Hot Springs Spa with a FreshWater Spa Ozone Generator?  This hose barb will work for you!
