While we can't confirm whether or not you will react to the elastomer grip, the company who makes our grip tubing developed it as an alternative to silicone and latex for the medical industry. The exact material compound is proprietary (they won't share it), and you can check out the data sheet here: https://www.kentelastomer.com/wp-content/uploads/2015/11/MDS-K8600-1.pdf

On the data sheet, it states that elastomer 'biocompatibility meets FDA food grade requirements USP Class IV.' 

We hope this helps, and if you have any other questions please feel free to contact us
