This Balboa Micro Magna Jet is designed for compatible grey-finish flow-path-set applications where the original assembly has become worn or less effective than it should be. In smaller jet seats, a complete replacement can make a meaningful difference because it refreshes the visible trim and the water-delivery character at the same time.

The flow-path-set design helps preserve the original seat feel the Micro Magna system was designed to provide. That matters because homeowners often notice when a seat no longer feels like itself, even if they cannot immediately identify which internal part has changed. Replacing the complete jet helps bring that identity back more cleanly.

The grey finish offers a more understated visible look than bright white while still blending well with many spa interiors. That can be particularly appealing in seats where the owner wants a refined and well-maintained appearance without adding stronger contrast.

Installed in the proper Micro Magna setup, this jet helps restore the intended flow character and gives the seat a cleaner, more cohesive finished look.

  • Complete jet for compatible Micro Magna flow-path-set applications
  • Helps restore original seat-level water behavior
  • Grey finish supports a balanced and refined appearance
  • Useful when original assemblies feel worn or underperforming
  • Improves both hydrotherapy quality and visible finish
