Hydrostatic Testing
Overview
Hydrostatic testing is a critical safety procedure used to assess the structural integrity and pressure-holding capacity of pressurized gas cylinders.
Using water as a safe medium, each cylinder is filled and pressurized beyond its normal operating limits to detect potential weaknesses, cracks, or leaks.
What’s Included
- Internal and external visual inspection
- Cylinder fill with water and pressurization
- Expansion measurement and leak detection
- Drying and preparation for return
- DOT-compliant test stamp marking and certification label
- Documentation of results for compliance tracking

All testing performed in compliance with DOT standards
DOT No. N623
Benefits
- Verifies cylinder strength and pressure capacity
- Detects early signs of fatigue or damage
- Ensures user safety and equipment reliability
- Extends the usable life of cylinder
Compliance & Standards
- All testing is performed in accordance with DOT (U.S. Department of Transportation) specifications
- Follows procedures outlined in CGA C-1, CGA C-6, and related regulatory publications
Ideal For
- SCBA breathing apparatus cylinders
- Scuba diving tanks
