A wall fitting provides the support that keeps a jet assembly aligned and secure, and this Balboa Micro Blaster Ultra-Pulse Wall Fitting is designed for compatible 1-3/4 inch hole-size applications where the original fitting has worn out or no longer supports the jet properly. When the wall fitting begins to fail, even a small jet can feel noticeably less stable and less finished than it should.

The 1-3/4 inch hole-size specification helps define the intended shell opening and is a major reason this part needs to be matched correctly. Wall fittings are not just background pieces. They affect how the whole assembly sits, how it feels when adjusted, and how polished the final repair looks once complete.

Because it supports Micro Blaster and Ultra-Pulse style applications, this fitting is especially useful in repairs where the owner wants to preserve the original seat behavior rather than substitute a more generic-looking or less application-specific part.

Installed in the proper setup, this wall fitting helps restore a stronger base for the micro jet assembly and contributes to a cleaner, more confidence-inspiring finished seat.

  • Wall fitting for compatible Micro Blaster and Ultra-Pulse applications
  • 1-3/4 inch hole-size format supports intended fit
  • Helps restore structural support at the jet position
  • Useful when original fittings are worn or unstable
  • Improves assembly confidence and visible repair quality
