After the introduction of eddy-current technology, Luxfer received reports of cracking in 6061-alloy cylinders. We accepted returns on about 1,200 of these cylinders to conduct extensive tests. Not a single cylinder was found to be cracked.
Luxfer recommends taking your cylinder to an authorized Luxfer service center or to an inspector trained by Professional Scuba Inspectors, Inc. (PSI) or the Association of Scuba Service Engineers & Technicians (ASSET).

It has come to Luxfer’s attention that a fraudulent website named ‘Luxfer.US’ has been established. This is not a Luxfer owned domain and none of its content has been generated by Luxfer. Within this fraudulent website, people have been encouraged to apply for an open Executive Assistant position, and this position DOES NOT EXIST. Luxfer is actively taking action to have this web-site taken down. We apologize any inconvenience this may have caused any innocent parties caught up in this fraudulent activity. ×
