A jet body is the structural foundation that the rest of the assembly depends on, and this Balboa Magna Jet Body is designed for compatible 2-5/8 inch hole-size applications where the original body has worn down or lost the secure fit needed to keep the seat feeling right. When a jet continues to feel weak or unstable after visible parts have been refreshed, the body is often the part that actually needs replacement.

The 3/8 inch barb and 3/4 inch slip relationship helps define the intended plumbing layout of this body, which is important because correct connection geometry affects both the way the assembly fits and the way the water path behaves. A good body replacement helps restore the seat from the inside out instead of only improving the visible surface.

Because this is a Magna application, proper matching helps preserve the original feel and support relationship of the seat. That can make the final repair feel much more complete than continuing to replace smaller visible pieces around a worn foundation.

Installed in the proper Magna setup, this body helps restore a more secure and better-aligned jet position, improving both structural confidence and everyday hydrotherapy performance.

  • Jet body for compatible Balboa Magna 2-5/8 inch applications
  • 3/8 inch barb and 3/4 inch slip layout supports intended fit
  • Helps restore the structural base of the jet assembly
  • Useful when deeper body wear affects seat performance
  • Improves stability and overall repair quality
