Pentair Micro Cyclone diffuser

The high temperatures and chlorine in your hot tub can fatigue the plastic clip which holds the spa jet in place. If you are having trouble with your Pentair jets popping out, this may be the solution. Remove the diffuser from the back of the jet and replace it.

Compatibility
This jet back is compatible with all Pentair Micro Cyclone jets with 14-15 mm diameter water entry point at the back of the jet, EXCEPT the 100% shut-off series. Some Micro Cyclone jets (like this one have an 18 mm pipe at the back ; this diffuser is not compatible with those jets.

Dimensions
Front diameter: 40 mm
Rear diameter: 14,5 mm (check this diameter on your old jet, to be sure that this part is compatible)
