Polarstar Fusion Engine Cylinder Input Fitting

Polarstar Fusion Engine Cylinder Input Fitting (V2, V3, M240)

Ensure proper air delivery within your HPA system with the PolarStar Fusion Engine Cylinder Input Fitting. This genuine OEM component is the original factory-installed fitting used in V2, V3, and M249/M240 Fusion Engine variants, designed to provide a secure connection between the internal cylinder and the incoming 6mm air line.

Because this fitting sits directly in the engine’s cylinder, it plays a critical role in maintaining consistent airflow throughout the system. It threads directly into the cylinder housing and serves as the primary interface for the 6mm macro line. As a result, replacing worn or damaged fittings is essential for preserving air seal integrity and ensuring stable shot-to-shot performance.

Moreover, this fitting features an M8 x 0.75 thread paired with a 6mm push-to-connect interface, making it a precise, factory-spec component for PolarStar systems. Each unit includes a new crush ring, which should always be replaced during installation to maintain a proper seal and prevent leaks under pressure.

For Australian users running HPA Gel Blaster builds, this part is a key maintenance item. It ensures reliable internal air routing within your Fusion Engine, which directly impacts efficiency and consistency. Whether you are performing a rebuild, fixing an air leak, or keeping critical spares on hand, this genuine PolarStar fitting delivers dependable, OEM-level performance.
