AEG AK Air Seal Upgrade Set (19.8 mm)

AirsoftParts Air Seal Set for AK AEG
It includes a POM piston head, silent cylinder head, full cylinder and a 19.8 mm nozzle. This combination is designed for AK47-type AEG rifles and provides a practical solution when replacing a major part of the air seal system or building a new configuration. The full cylinder uses its entire working volume, while the piston head, cylinder head and nozzle form interconnected parts of the compression system. Proper operation depends not only on the air seal of the individual parts, but also on how well they match the specific gun and hop-up chamber. In particular, the 19.8 mm nozzle length should be compared with the original part before installation, as different AK models and manufacturers may use different air seal component dimensions.
Key Features

Four Air Seal Components in One Set
The set combines a piston head, cylinder head, cylinder and nozzle, so the main interconnected air seal components do not need to be purchased separately.

POM Piston Head
The set includes a POM piston head that moves inside the cylinder and uses its seal to generate the required air pressure as the piston moves.

Silent Cylinder Head
The silent cylinder head closes the front section of the compression chamber, and its design also helps dampen the mechanical impact of the piston assembly.

Full Cylinder
The full non-ported design allows the entire working volume of the cylinder to be used. Correctly matching the cylinder volume to the length and inner diameter of the barrel is important for efficient operation of the air seal system.

19.8 mm Nozzle
The set includes a 19.8 mm nozzle. Before installation, it is advisable to verify the required length for the specific combination of gearbox and hop-up chamber used in the A..
