PolarStar Kythera SA O-Ring Kit
The PolarStar Kythera SA O-Ring Kit is the replacement O-ring set for the PolarStar Kythera SA HPA engine. The Kythera SA is PolarStar’s standalone self-aspirating Kythera variant — a version of the Kythera engine that operates without a traditional HPA tank, using a standalone CO2 or dedicated supply format. Like all HPA-type engines, the Kythera SA contains O-rings at its piston, valve, and sealing positions throughout the air path. These O-rings degrade with use — causing air leaks, velocity loss, and inconsistent cycling in the Kythera SA.
OEM PolarStar replacement O-ring kit for Kythera SA engine maintenance. For Kythera SA operators experiencing air leaks or declining velocity, this complete O-ring kit provides the correct sealing replacement set for the SA variant of the Kythera engine.
