The Novritsch HPA Connector - EU Type is designed to screw into a compatible gas magazine, replacing the gas inlet valve. This then allows you to attach an EU spec HPA line to your magazine. HPA is popular due to its consistency and performance in cold weather games, however, it does require a lot of modification which is not covered by the Patrol Base or Novritsch warranty.

You must ensure that your HPA system is EU spec and not US spec as they are not cross-compatible and the Novritsch HPA Connector - EU Type will not work with a US spec HPA line. Make your compatible gas magazines HPA-ready so you don't notice a dip in performance during those cold winter skirmishes, or you desire an incredibly consistent performance all year round.

Much like CO2 gas, airsoft HPA isn’t particularly affected by the cold, which makes it ideal if you’re looking for something to use in all weather conditions. Our HPA is also compatible with a range of gas-powered weapons like airsoft assault rifles, gas submachine guns and more.
