The Huben Specialized Maintenance Tool Kit V2 is a complete, workshop-grade overhaul and service kit engineered specifically for deep disassembly, valve maintenance and resealing of Huben K1 and GK1 PCP airguns.

Upgraded from the original release, the V2 kit adds an expanded set of dedicated tools, including non-marring Delrin installation guides, precision pushrods and specialised seal extractors. Together they let technicians and owners safely service complex internal valve mechanisms and regulators without stripping threads, marring critical sealing surfaces or pinching O-rings.
