G18C / AAP01 Piston Head | TTI

G18C / AAP01 Piston Head | TTI – for your replica

This piston head is developed for GBB pistols such as the AAP-01 and G18C models. The component ensures the seal between the piston and cylinder during the firing cycle. You replace the piston head when you want more consistency with HPA conversions or when your current rubber seal is worn out due to intensive use with Green Gas or propane. The airsoft piston head upgrade is specifically designed to handle the higher pressure of these gases.

Technical specifications

The TTI piston head is manufactured from aluminium with a red anodised finish. The lightweight design reduces the mass of moving parts in your blowback unit. The reinforced rubber seal has a thicker construction than standard seals, making it more resistant to the forces in HPA setups. The central mounting fits the piston rod of compatible GBB pistols.

Compatibility and application

This piston head is suitable for WE and Action Army AAP-01 replicas, as well as compatible G18C models. The component fits both standard gas setups and HPA conversions. Installation requires disassembly of your blowback unit – experience with GBB internals is recommended. Always check the fitment with your specific piston and cylinder combination.
