TECAFORM Piston Head

AirsoftParts TECAFORM Piston Head Made From CNC-Machined POM
The combination of material and lightweight design results in a weight of just 9.3 g, reducing the moving mass of the piston assembly and therefore the mechanical stress generated on impact. Due to its low weight, the manufacturer also recommends it for V2 gearboxes. The front features 9 holes through which air flows beneath the sealing O-ring during compression. The pressure expands it towards the cylinder wall and helps provide an effective seal for the piston assembly. The piston head also features an axial ball bearing that allows the spring to rotate more freely during compression, reducing torsional stress and contributing to longer spring life. In a comparison with a standard air seal system and an M120 spring, the manufacturer measured an approximate muzzle velocity increase of 5 m/s. However, this is not a guaranteed increase, as the final performance depends on the complete configuration and air seal of the specific gun.
Key Features

Low Weight of 9.3 g
The lightweight TECAFORM construction weighs just 9.3 g, reducing the moving mass of the piston assembly and mechanical stress on the gearbox during the operating cycle.

9 Holes for Pressure-Assisted Sealing
Air flowing through the 9 holes on the front expands the sealing O-ring against the cylinder wall, helping to provide an effective seal during compression.

CNC-Machined TECAFORM (POM)
The piston head is precision CNC-machined from TECAFORM engineering plastic, also known as POM, combining low weight with the durability required for a piston assembly.

Axial Ball Bearing
The integrated axial ball bearing allows the spring to rotate more freely during compression, reducing unwanted twisting and co..
