    Counterfeit cylinders have entered the US.

Hudson Technologies has warned that non-compliant recovery cylinders have entered the United States market.

These cylinders are illegal and unsafe, the warning said.

Hudson Technologies said it will not accept these cylinders.

“Shipments that include counterfeit cylinders will be refused. Do not purchase, use, or transport counterfeit cylinders,” the warning said.

The warning also included advice on how to identify the counterfeit cylinders.

These illegal cylinders have been marketed under the following names: Olenyer, Fahkns, Vevor but they may also be sold under other branding.

The cylinder sizes are 30 and 50 lb. cylinders. However, these counterfeit cylinders are smaller than DOT-compliant 30 and 50 lb. cylinders.

Hudson Technologies said these cylinders are not manufactured to US Department of Transportation (DOT) specifications and DOT markings are missing from the steel collar.

Moreover, there is no date of manufacture or serial number.
