A long-nozzle jet body helps define both the support and the water path of the assembly, and this Balboa Hydro version is designed for compatible 2-3/8 inch hole-size applications where the original body has worn enough that the seat no longer feels properly supported. When the deeper parts of a jet wear out, visible trim replacement often stops being enough.

The 1-1/2 inch slip relationships help preserve the intended plumbing and shell-side fit of the original setup, which matters because the body affects how the whole jet sits and how naturally the seat performs once it is back in service. A strong repair starts with the correct foundation under the visible face of the jet.

The long-nozzle style gives this body a specific role in applications where the internal path and reach need to match the original seat design closely. That makes proper replacement especially important if the goal is to restore the seat rather than merely make it functional again.

Installed in the correct Hydro setup, this body helps restore stronger structure and contributes to a more complete and dependable long-nozzle jet repair.

  • Long-nozzle jet body for compatible Hydro applications
  • 2-3/8 inch hole-size format supports intended shell fit
  • 1-1/2 inch slip layout helps preserve plumbing alignment
  • Useful when deeper body wear affects seat performance
  • Improves stability and overall repair quality
