Polarstar Micro Reg Complete O-Ring Seal Set

Polarstar Micro Reg Complete O-Ring Seal Set

Complete Seal Set, Micro Reg (GEN1 & GEN2)

Maintain peak HPA performance with the Polarstar Micro Reg Complete O-Ring Seal Set, engineered specifically for both GEN1 and GEN2 Micro Regulators. Over time, seals naturally degrade due to pressure cycles, contaminants, and wear. As a result, even minor O-ring damage can lead to inconsistent output pressure, air leaks, or regulator creep.

This complete seal kit provides all critical internal O-rings required to restore your Micro Reg to factory-level sealing performance. Because it uses high-quality Buna 70 rubber compounds, it ensures durability under high-pressure conditions while maintaining flexibility for reliable sealing. Consequently, your regulator delivers consistent PSI output, improved efficiency, and smoother operation.

Furthermore, this kit is essential for routine maintenance and preventative servicing. Whether you are running a high-performance HPA gel blaster or airsoft setup, replacing worn seals significantly reduces the risk of pressure spikes and system instability. In addition, it helps extend the lifespan of internal regulator components by preventing air bypass and contamination ingress.

Importantly, this is a genuine PolarStar service kit, ensuring exact fitment and compatibility. Unlike generic O-ring replacements, these seals are precision-sized for the Micro Reg’s internal architecture. Therefore, installation is straightforward and performance remains consistent with original specifications.

Full Component List:

• 2 × M1.5 × 4.5 O-rings (Body ID)
• 1 × M2.0 × 14.0 O-ring (Piston OD)
• 1 × Base sea
