Compatibility is crucial when purchasing HPA Fittings & Unit Parts because ensuring each component works with your existing setup avoids installation issues and performance problems. It's best to look for fittings and parts explicitly designed for your particular HPA system, such as those made for PolarStar Fusion Engines or specific regulator types. A wide range of options exist, from poppet valves and shims tailored for Fusion Engines to fittings compatible with Palmers and AKA regulators. For example, the S2 Airsoft Designs Lightning Banjo is made for V2 GEN 3 and M249 Fusion Engines, while the Amped Airsoft 6mm QD Male 1/8" NPT Fitting works with Palmers and AKA regulators. This variety ensures you can find a product tailored to your specific HPA setup.
