AirsoftParts TECAFORM 2013 Piston Head With Guide O-Ring
AirsoftParts TECAFORM 2013 piston head is a CNC-machined component for AEG air seal systems, made from TECAFORM (POM) engineering plastic. 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 plastic piston head body.
Axial Ball Bearing
The integrated axial ball bearing allows the spring to rotate more freely during compression, reducing twisting and contributing to longer spring life.

Frequently Asked Questions (FAQ)
What Is the Guide O-Ring on the Piston Head For?
The guide O-ring helps keep the piston head centered inside the cylinder and reduces unwanted contact with the cylinder wall. The main seal is provided by a separate sealing O-ring.
What Is the Advantage of the Through-Locking Nut?
The locking nut distributes the clamping force of the screw over a larger area of the piston head. This reduces localized stress on the POM body and the risk of the screw being pulled out of the piston head.
What Is the Maximum Spring That Can Be Used With the TECAFORM 2013 Piston Head?
The manufacturer recommends use with springs up to M150. In higher-performance builds, the other mechanically stressed gearbox components must also be appropriately rated.
Which Gearboxes Is the Piston Head Compatible With?
According to the manufacturer, the AirsoftParts TECAFORM 2013 is designed for V2, V3 and V7 gearboxes. During installation, it is advisable to verify the correct operation of the complete piston assembly and its interaction with the cylinder and other components.
