* Gasket shore hardness is 70 +/- 5. Fastener recommendation is: Either the bolt or the nut, and preferably both, should be zinc-plated to ensure minimal friction.• zinc-on-zinc, with or without lube• zinc-on-stainless-steel, with or without lube• stainless-on-stainless, with lube onlyCadmium-plated fasteners are also acceptable with or without lubrication. Galvanized and carbon-steel fasteners are notrecommended. Use a copper-graphite anti-seize lubricant to ensure smooth engagement and the ability to disassemble andreassemble the system easily.
