All Saf-T-Cradles and Pallet Headers feature manifolds by Superior Products*. These manifolds link your cylinders together within your cylinder banks, making them indispensible in your gas operation. The manifold body is machined from a 1.5” yellow brass bar. Each stainless steel pigtail is teon lined for either standard gas service or tefzel for high purity and lighter than air gases and are available as rigid copper, flexible stainless steel or armored for heavy duty use. Just specify the CGA number when ordering to make sure you get the right pigtails.
