These 4" x 8" aluminum capping rings for use with pad caps are a lightweight version of our standard capping rings. These rings weigh just 1.7 lbs. each as compared to the standard rings, which weigh 4.6 lbs. These capping rings reduce the prepared cylinder by almost 9 lbs., which for those breaking large numbers of cylinders makes a big difference after a long day. Capping Rings are sold individually, but require two for use.
