Exactly built and designed by ARO, Authentic ARO Parts are the only replacement parts you can count on to restore your ARO equipment to its original performance and quality, while backing up your warranty. Though a part may look like an ARO part, unless it carries the Authentic ARO Parts name and was bought from one of our authorized distributors, it does not carry the ARO promise and runs the risk of subpar chemical, metallurgical, and mechanical properties. Don’t risk your application. Don’t risk your ATEX and CE certification. Choose only Authentic ARO Parts the first time and every time.
