AirsoftParts replacement sealing O-ring for a duralumin nozzle is a service part designed to restore the correct seal between the nozzle and cylinder head. During operation, repeated nozzle movement gradually deforms and wears the seal, which can lead to reduced air seal performance. We recommend replacement every 10,000 shots or once a year.

This expert product description was prepared by the ANAREUS.cz expert team. All rights to this unique content are tied to the anareus.cz domain.AirsoftParts duralumin nozzle set for ARES / Delta Armory vz.58 contains three length variants of 49.2 mm, 49.4 mm and 49.6 mm, allowing the nozzle to be matched more precisely to the specific air seal system and hop-up chamber setup. In practice, even a difference of a few tenths of a millimeter can affect how the nozzle contacts the hop-up bucking and whether the gun feeds BBs correctly and maintains a proper air seal. All three nozzles are CNC-machined from EN AW 6012 duralumin and use one internal O-ring to seal the connection with the cylinder head. When finding the correct nozzle length, we recommend checking both the air seal and feeding reliability – the longest nozzle is not automatically the best choice, as excessive length can reduce the space available for feeding a BB into the hop-up chamber.
The set contains 49.2 / 49.4 / 49.6 mm nozzles, allowing the length to be adjusted in 0.2 mm increments to better match the specific gun setup.
The correct nozzle length is important for proper contact with the hop-up bucking and sufficient space for feeding a BB. The set allows both requirements to be balanced in practice.
All three nozzles are made from EN AW 6012 duralumin using CNC machining, allowing precise production of the individual length variants.
Each of the three nozzles uses its own internal sealing O-ring, which helps seal the connection between the nozzle and cylinder head.
Instead of a single length, the set offers three variants in 0.2 mm increments, making it easier to find a suitable setup when building or servicing the vz. 58 air seal system.
Differences between individual guns and the components used may require fine-tuning of the nozzle length. The 49.2 / 49.4 / 49.6 mm variants allow you to find a suitable setup in 0.2 mm increments.
No. A longer nozzle may provide better contact with the hop-up bucking, but if it is too long, it may not retract far enough and can interfere with BB feeding. The aim is to find a length that provides both a good air seal and reliable feeding.
After installation, check the air seal, free movement of the nozzle and, most importantly, reliable BB feeding. If changing the length solves an air leak but causes feeding problems, that variant is not optimal for the specific setup.
Yes. The package contains 3 nozzles and 3 sealing O-rings, meaning one O-ring for each length variant.
