AirsoftParts DURAL 2013 Piston Head With Guide O-Ring
AirsoftParts DURAL 2013 piston head is a CNC-machined component for AEG air seal systems, made from EN AW 6012 T6 duralumin with an electroless nickel-plated finish. In addition to the main sealing O-ring, the design also uses a guide O-ring that helps center the piston head inside the cylinder and reduces the risk of the metal head contacting the cylinder wall. Nine holes on the front direct air beneath the sealing O-ring during compression, expanding it against the cylinder wall and promoting effective sealing. The design also incorporates an axial ball bearing that allows the spring to rotate more freely during compression and reduces torsional stress. The rear section of the head is lightened to reduce the moving mass of the assembly. The manufacturer specifies use with springs up to M170 and compatibility with V2, V3 and V7 gearboxes. The piston head is made in the Czech Republic.
Key Features
EN AW 6012 T6 Duralumin for Springs up to M170
The CNC-machined EN AW 6012 T6 duralumin construction is designed according to the manufacturer for builds with springs up to M170 and offers high mechanical durability.
Guide O-Ring for Proper Centering
The separate guide O-ring helps keep the piston head centered inside the cylinder and reduces the risk of unwanted contact between the metal head and 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 effectively seal the piston assembly.
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.
Electroless Nickel-Plated Surface
Electroless nickel plating creates a smooth surface layer while also protecting the surface of the CNC-machined duralumin component.

Frequently Asked Questions (FAQ)
What Is the Second Guide O-Ring For?
The guide O-ring is not primarily used as the main seal. Its purpose is to help center the metal piston head inside the cylinder and reduce the risk of unwanted contact between the head and the cylinder wall.
What Spring Strength Is the DURAL 2013 Piston Head Designed For?
The manufacturer specifies M170 as the maximum recommended spring. When building a higher-performance gearbox, the other stressed components must also be appropriately selected for the load.
How Does Pressure-Assisted O-Ring Sealing Work?
As the piston moves, air flows through the 9 holes on the front beneath the sealing O-ring. The pressure expands it towards the cylinder wall, promoting proper sealing during compression.
Which Gearboxes Is the DURAL 2013 Compatible With?
According to the manufacturer, the piston head is compatible with V2, V3 and V7 gearboxes. During installation, it is advisable to check the correct operation of the entire piston assembly and its interaction with the cylinder and other components.
