This complete set ensures your Micro Regulator operates at peak performance. Recommended annual replacement for frequent players; essential if you notice pressure fluctuation or air leaks.

Compatibility & Upgrades

This seal set is engineered specifically for PolarStar Micro Regulators and will not fit other HPA regulator brands or models. It is a drop-in replacement requiring no modification.

If you own multiple PolarStar platforms, stock spares – seal kits are small, affordable, and essential spares to have on hand.
