Piston Head + Nozzle Valve Blocker | WE G17 / G19 | TTI

This piston head set with nozzle valve blocker is designed for WE G17 and G19 GBB pistols. The component improves the gas seal and cycle efficiency of your replica. The piston head optimises air compression during firing, whilst the nozzle valve blocker prevents gas leakage and ensures consistent pressure. This airsoft piston head upgrade is particularly valuable when you notice your replica is producing inconsistent FPS values or when you want to improve overall reliability during skirmishes.

Technical characteristics

The TTI piston head is manufactured from anodised aluminium with a red finish for the upper section. The nozzle valve blocker is made from reinforced polymer in black. The complete component has a precise fit specifically for WE G-series nozzles and piston assemblies. The O-ring seal on the piston head ensures optimal compression. The weight remains low so as not to negatively affect the cycling speed.

Compatibility and application

This piston head set fits specifically on WE G17 and G19 GBBR pistols. The component is intended for players who want to improve their gas efficiency or resolve issues with inconsistent performance. Installation requires disassembly of the slide and nozzle assembly, which demands normal technical experience. The upgrade fits within both standard and tuned builds and is especially useful in combination with other internal upgrades such as enhanced recoil springs or metal slides.
