Are Sheng insists quality on each product. Our AMER stainless steel flexible connector uses non-toxic PVC core, covered with multi-filament nylon fiber. Above the PVC core, it is a clear vinyl shell. At last, the appearance is braided with 304 stainless steel wires.
We use non-toxic beveled rubber washer with brass barb and stainless steel ferrule. The nut on both ends is brass material. We focus on each detail when assembling all the parts.
