It is a simple yet essential maintenance solution for resolving air leaks, improving consistency, and ensuring reliable operation in high-performance HPA builds. Because the F1 platform relies on precise air delivery, even minor seal wear can reduce efficiency or cause inconsistent shot behaviour. This complete set includes multiple Buna 70 o-rings covering critical areas such as the nozzle exterior, cylinder interface, doughnut (donut) seals, and barb fitting. As a result, it allows users to carry out full servicing without needing to source individual seal sizes. For gel blaster and airsoft users running HPA systems in Australia, having the correct manufacturer-specified seal kit simplifies maintenance and reduces downtime.
