A jet body is the hidden support structure that gives the rest of the jet assembly a stable and properly aligned foundation, and this Balboa Hydro Jet Body is designed for compatible 2-3/8 inch hole-size applications where the original body has worn out or become unreliable. If the seat still feels off after visible parts have been replaced, the body is often where the real issue starts.

The 1-1/2 inch slip relationships help define the plumbing and assembly layout this body was meant to support. That correct fit is important because the body affects both how the assembly sits in the shell and how naturally water moves through the jet.

Replacing the jet body is a particularly smart repair when the owner wants something more complete than a cosmetic refresh. It restores the structural core of the seat and gives the other parts of the assembly a better chance of performing the way they were designed to.

Installed in the proper Hydro setup, this body helps restore a stronger and more dependable jet position, improving both the long-term stability of the assembly and the confidence of the finished repair.

  • Jet body for compatible Hydro 2-3/8 inch hole-size applications
  • 1-1/2 inch slip configuration supports intended plumbing fit
  • Helps restore the structural base of the jet assembly
  • Useful when deeper body wear affects seat performance
  • Improves stability and overall repair quality
