TECAFORM 2013 Piston Head

AirsoftParts TECAFORM 2013 Piston Head With Guide O-Ring
Weighing just 8.7 g, it helps keep the moving mass of the piston assembly low, while the manufacturer recommends use with springs up to M150. The front features 9 holes through which air flows beneath the main sealing O-ring during compression. The pressure expands it against the cylinder wall and promotes effective sealing. A second guide O-ring helps center the piston head inside the cylinder and reduces unwanted contact with the cylinder wall. Another important design feature is the locking nut passing through the center of the piston head, which distributes the clamping force over a larger area and reduces the risk of the mounting screw being pulled out of the POM body. The integrated axial ball bearing allows the spring to rotate more freely during compression and reduces torsional stress. The manufacturer states compatibility with V2, V3 and V7 gearboxes. Made in the Czech Republic.
Key Features

Low Weight of 8.7 g
The CNC-machined TECAFORM (POM) construction weighs just 8.7 g, helping to keep the moving mass of the piston assembly low.

Two O-Rings With Different Functions
The main O-ring provides pressure-assisted sealing of the piston inside the cylinder, while the second guide O-ring helps center the piston head and reduces contact with the inner cylinder wall.

9 Holes for Pressure-Assisted Sealing
The 9 front holes direct air beneath the sealing O-ring during compression, expanding it against the cylinder wall and helping to properly seal the piston assembly.

Through-Locking Nut
The nut passing through the center of the piston head distributes the clamping force over a larger area, reducing the risk of the mounting screw being pulled out of the p..
