PolarStar HPA Nozzles

PolarStar is the most widely used HPA engine brand, and its Fusion Engine, JACK and Kythera engines use PolarStar-specific nozzles. The nozzle is offered in different lengths to suit the receiver (M4, AK, SR25 and others), so you match the engine first, then the nozzle length for your platform. PolarStar nozzles do not fit a Wolverine or Redline engine.

Which engines share a nozzle?

HPA nozzles are engine-specific, not gearbox parts: An HPA (High Pressure Air) nozzle is part of the HPA engine that replaces the AEG piston and cylinder, not a standard AEG air nozzle. Each engine family (PolarStar, Wolverine, Redline, GATE) uses its own nozzle, and they do not interchange. Within one engine family, nozzles are often offered in different lengths to suit the receiver (for example M4 versus AK versus SR25 lengths). Match the engine first, then the length for your platform.

Fitment notes & exceptions

Match the engine, then the length: A PolarStar nozzle fits PolarStar engines only. Within the range, choose the nozzle length for your receiver (M4, AK, SR25 and so on). A PolarStar nozzle is not a Wolverine or Redline part.
Length is by receiver: PolarStar sells nozzles for each engine (the Fusion Engine and the JACK) in several numbered lengths so the engine fits different guns. Buy the length that matches your receiver, and if you change platforms you may need the matching nozzle length for the new gun.

PolarStar nozzle buying guide

How to pick a PolarStar nozzle

Confirm your engine (Fusion Engine, JACK, Kythera), then choose the nozzle length for your receiver (M4, AK, SR25 and others). Buy the part listed for your exact engine and length.

What to check before you buy

Confirm the engine model and the receiver length you need. If you move the engine to a different gun, check whether a different nozzle length is required.

Frequently asked questions

Are PolarStar nozzles the same across engines?

Not exactly. The Fusion Engine (a full gearbox replacement) and the JACK (a cylinder conversion) each have their own nozzle line, though both use a numbered length system so you can match the nozzle to your receiver. Buy the nozzle listed for your specific PolarStar engine, then pick the length for your gun.

Does a PolarStar nozzle fit a Wolverine engine?

No. HPA nozzles are engine-specific. A PolarStar nozzle does not fit a Wolverine or Redline engine. Buy the nozzle made for your engine.

How many PolarStar nozzles does Airsoft Upgrades track?

We currently track 214 PolarStar nozzles across 20 retailers, starting at $2.67.
