As a reliable supplier to South America and various global markets, continuous dispatching is a standard part of our daily operations. Our relationship with our Brazilian clientele has long been built on a foundation of mutual trust, sustained by our consistent product quality, reasonable pricing, and reliable delivery times. This latest batch of valve bosses is simply another reflection of that ongoing, stable cooperation.

1. Premium Q235 Steel Material

 

 

We utilize high-quality Q235 carbon steel, known for its excellent weldability, ductility, and outstanding mechanical strength. This ensures that the cylinder bung can be seamlessly welded to the cylinder guard and body, providing a reliable and leak-proof foundation for the cylinder valve.

2. Strict Quality Control & 100% Traceability

 

 

At Shanghai LUZHEN, safety is our top priority. Every batch of LPG Cylinder Bung undergoes rigorous dimensional inspection and strict mechanical testing before leaving our factory. We provide comprehensive Quality Inspection Reports with every shipment, completely eliminating any quality concerns for our clients and ensuring zero-defect delivery.

3. Tailored Configurations for Diverse Cylinder Designs

 

 

To adapt to the diverse LPG cylinder specifications and capacities across the South American market, we routinely manufacture and supply two distinct configurations tailored specifically to our long-term partners' production lines:

 LPG Cylinder Bung with Holes: Featuring a precise internal thread pre-drilled for fusible plugs, enhancing cylinder safety against over-temperature risks.

 LPG Cylinder Bung without Holes: A standard, robust design optimized for classic cylinder setups.
