Tested To ISO 11118 Limits

Quality is not a slogan — it is a checklist. Every batch passes hydraulic, airtight and visual inspection with batch-number traceability before it is cleared for export.

Hydraulic Pressure Test

Cylinders are rated at 120 BAR working pressure (Ø70 series optionally 150 BAR) and verified at a 180 BAR test pressure (optionally 225 BAR for Ø70). Batch results are recorded for full traceability.

Airtight Leak Test

Every single cylinder — not just samples — is leak-tested with its valve pre-installed at the factory. Units showing any seal imperfection are rejected before packing.

Gas Purity Analysis

Each filling batch is analyzed for purity, moisture and residue. A Certificate of Analysis (COA) is issued per batch and supplied with your shipment.

Weight & Dimension Check

Fill weight is verified against specification so your customers receive exactly what the label promises, and key dimensions are checked against the engineering drawing for each series.

Visual & Coating Inspection

Every unit is visually inspected for dents, rust and surface defects. Coating, color and printed branding are checked against your signed pre-production sample.

Batch Traceability

A batch number is printed on every unit and carton. If you ever have a question about a shipment, we can retrieve its complete inspection history — hydraulic, airtight, visual and filling records.
