Description

Specification

Ningbo Zhengxin (ZX) Scuba Cylinders represent the industry standard for recreational, technical, and commercial diving.

Extruded from AA6061-T6 aerospace-grade aluminum, these tanks are highly favored over traditional steel counterparts due to their exceptional resistance to internal scaling and external saltwater oxidation.

Engineered to provide neutral to slightly positive buoyancy as the gas is consumed, they reduce diver fatigue and improve underwater trim. Available in both DOT-3AL and ISO 7866 (PED/TPED) configurations, these high-capacity cylinders serve as the reliable backbone of dive fleets worldwide.

Advantages:

Exceptional Corrosion Resistance: Eliminates the risk of internal scaling and withstands harsh saltwater environments better than steel.
Optimal Buoyancy Control: Engineered for neutral to slightly positive buoyancy, reducing diver fatigue and improving underwater trim.
Lightweight yet Durable: Easy to handle and transport out of the water while ensuring robust safety performance.
Ready for Retail: Optional pre-installed valves and tank boots reduce assembly steps for importers and distributors.
