Spa Jet Internals and Inserts
Spa Jet Internals are the part of a spa or hot tub jet that can be removed and replaced with an alternative jet type, or with the same. Jet Internals are not universal, but will fit only the Jet Body of the spa jet for which they are designed. If you do not see your spa jet internal or insert below, check in the Eyeballs or Wall Fittings category for your particular spa jet style.
To remove a spa jet internal, many just unthread, counter-clockwise for removal. Others spa jets may have a retaining ring or escutcheon plate *(trim ring) that first needs to be removed. A small number of spa jet internals are secured with locking tabs that require the use of a spa jet removal tool.
