PolarStar Airsoft Input Fitting for Drop-In HPA Cylinder Kits

If you need a new connection point for your hose line to plug into your HPA engine, you're in luck! The PolarStar Airsoft Input Fitting for Drop-In HPA Cylinder Kits is compatible with the PolarStar Airsoft F2™, F1™ and JACK™ drop-in cylinder kits. This connector creates a secure point for a QD air line to attach. It has 1/4-28 threads and is not compatible with the PolarStar Airsoft Kythera™ SA Mechanical HPA Engine Conversion Kit. There is no input line installed on this fitting, so make sure you have the additional products before installation.
