Product Details

Tri-Covers® are high purity foam caps designed to block and protect sanitary ends. They securely lock in place following clean-out-of-place (COP) procedures and can be installed and remove with ease using one hand.

Tri-Covers are made from high purity, inert and UV stable cross-linked polyethylene foams. The foam material is FDA approved and is USP Class VI grade.

Nitrogen is the only blowing agent used when the foam is made. No greenhouse gases such as carbon dioxide or ozone depleting materials, such as CFCs or HCFCs, are introduced in the process. The foam material will not grow bacteria or mold.

Tri-Covers have excellent chemical tolerance and can be cleaned with acid, alkaline or alcohol based cleaners. They are reusable and come in a variety of sizes and colors.
