Product Change Notification FIT Series

May 26, 2020


Dear Valued Customer,

The Alpha Wire portfolio requires regular review to ensure our products continue to offer the most updated features and benefits, in addition to the highest quality. This letter serves as your formal notification of changes to select FIT Heat Shrink Tubing products.

As of January 1, 2019, Mil-Spec grade tubing was required to be listed per the SAE AS23053 specification and documented on the Qualified Product List (QPL). As a result, the following Alpha Wire series have been qualified to the new AS23053 specification: F221, F221V, F221B, F321, and F750. A detailed list of all affected part numbers can be found at the end of this letter.

Additionally, the AS23053 specification has transitioned from shelf life to dimensional life, when referring to the usable life of the product. The dimensional life applies to the expanded ID and recovered ID, and wall thickness dimensions, and the duration is specified in the SAE detail specification (i.e. AS23053/5).

Please contact your Alpha Wire sales representative or channel partner.
