This pressure test evaluates your cylinder’s structural integrity by measuring its expansion under high pressure, ensuring it can safely handle normal fill pressures. Required every 5 years, hydro testing is a critical safeguard against metal fatigue and cylinder failure.

This specialized cleaning process removes hydrocarbons, oils, and contaminants from your cylinder that could ignite or combust when exposed to high-concentration oxygen or nitrox. It’s required for any cylinder used with gas mixtures above 40% oxygen, ensuring safe and compliant fills.

This process uses an abrasive media (like chain, ceramic pellets, or aluminum oxide) tumbled inside the cylinder to remove internal rust, scale, and corrosion that a standard VIP can’t fully address. It’s typically recommended for steel tanks showing internal oxidation, restoring the cylinder to a safe, fillable condition before its next inspection.

This non-destructive electromagnetic test detects hidden cracks and corrosion in the cylinder neck threads, and is specifically required for older aluminum cylinders (6351-T6 alloy, manufactured 1972–1990) prone to sustained load cracking. If you dive with a vintage aluminum tank, this test is essential to verify it’s still safe to fill.

This service disassembles your cylinder valve to replace worn O-rings, seats, and internal components while thoroughly cleaning it of hydrocarbons and contaminants for safe use with high-oxygen and nitrox mixes. Regular valve rebuilds prevent leaks, sticking, and failures, keeping your valve operating smoothly and safely dive after dive.
