We wanted to make you aware of a recent change that our supplier of aluminum cylinders has made to the branding of their cylinder.

The part numbers/NIOSH model numbers for the affected cylinder & valve assemblies are: 5-978-1, 10008298, 10061364, 818159, 10008299, 10061365, 802191.

This change to branding does not affect the performance or specification of the cylinders in any way and all fielded units with both prior and new branding are acceptable for use.

Our current supplier, Metal Impact will now do business under the name Thunderbird Metals. As part of this rebrand by our supplier, they will change the name of the aluminum cylinder that is supplied to MSA to Thunderbird Cylinders (TBC) from Metal Impact East (MIE). The only change you may notice is a slight change to the brand on the cylinder.
