The cylinder head is made of duralumin EN AW 6012. On a CNC machining center. This cylinder head is a completely innovative design, among the most fundamental differences are the impact surface and the one-piece seal, perfect surface treatment for maximum slipperiness, a huge impact surface.

!! The silent NBU cylinder head can only be combined with an NBU nozzle and cylinder. !!

Surface treatment:
A thin layer of nickel is chemically applied to the surface of this cylinder head, which significantly increases the surface's lifespan and slipperiness. Basic information:

• Hardness after plating 660-850 HV (58-63 HRc)
• Excellent corrosion resistance
• High abrasion resistance
• Inherent surface lubricity
• Glossy appearance
• Uniform layer

Advantages:

• Perfect sealing of the space between the cylinder head and the cylinder
• Double seal (cuff + sealing ring)
• Large rubber impact surface suitable for even the strongest springs
• Seal and impact surface in one piece => perfect seal
• Extremely smooth surface thanks to quality nickel on the surface => easy nozzle movement
• High durability
