NBU Duralumin Nozzle

AirsoftParts NBU Duralumin Nozzle for Bore Up Air Seal Systems
It is CNC-machined from EN AW 6012 T6 aluminium alloy and features one internal sealing O-ring that seals the connection between the nozzle and cylinder head outlet during movement. The key difference compared to the standard version is the NBU dimensions – this nozzle must be combined with an NBU cylinder head and is not compatible with a standard cylinder head. Depending on the specific length, the weight ranges from 0.8 to 1.3 g. In addition to choosing the NBU version, selecting the correct nozzle length is also important, as its dimensions affect contact with the hop-up bucking, air seal and reliable BB feeding.
Key Features

For NBU / Bore Up Air Seal Systems
The nozzle has NBU dimensions and is designed exclusively for the corresponding NBU cylinder head. It cannot be correctly combined with a standard cylinder head.

CNC-Machined EN AW 6012 T6 Duralumin
The nozzle is precision CNC-machined from EN AW 6012 T6 duralumin, which offers high strength while maintaining a low weight for this moving component.

Internal Sealing O-Ring
One O-ring inside the nozzle seals its connection with the NBU cylinder head and helps reduce air loss in this part of the air seal system.

Low Weight
Depending on the specific length variant, the nozzle weighs only 0.8–1.3 g, so it does not unnecessarily increase the weight of the moving parts of the feeding mechanism.

Made in the Czech Republic
Precision CNC machining is carried out in the Czech Republic, and the nozzle is designed for building, servicing and optimizing NBU air seal systems in AEGs.
