This is what we do when we test your Cylinder.

This is to prepare the cylinder for inspection.

The Cylinder Boot is Removed

The Valve is Removed

Outside Inspection

The outside of the cylinder is methodically and carefully inspected for Rust, dents, bulges and scrapes.

Thread Inspection

The cylinder neck threads are extensively inspected and tested with a calibrated gauge

( Go-No- Go)

Internal Inspection

The cylinder is checked inside with an endoscope

(if it fails due to rust then it can be shot blasted but will need to be hydrostatically tested)

Valve Inspection

The valve threads are extensively inspected and tested with a calibrated gauge( Go-No- Go)

Both the cylinder threads and the regulator threads (if any) are checked.

The Din Thread are the most common failure point on a Valve.

And refitted to the correct torque.

Cylinder is Stamped
