This replacement kit is intended to align valve components from earlier GK1 production batches with GK1 V3+ and V3+R standards. It can also be used as a direct replacement kit for GK1 V3+ and V3+R units when valve components need to be replaced.

Note: 

• The appearance of the kit may vary slightly between production batches. These differences do not affect function—each version serves the same purpose and meets V3+/V3+R specifications.
• To ensure proper sealing and performance, all components included in the kit must be replaced together. Mixing parts from different versions may result in sealing issues or inconsistent performance.
