I-Line fittings consist of interlocking flat face ferrules, gaskets and clamps. The metal-to-metal design prevents over compression by the clamp. I-Line fittings can withstand higher vibrations, temperatures and pressures than other available connections. Our fittings meet or exceed 3-A standards with an ID polish of 180 Grit or 25 Ra on the Inside of the Tube and a 150 Grit or 32 Ra on the Outside of the tube. Available in T304/304L or T316/316L stainless steel I-Line Fittings are found primarily in Bakery, Beverage, Brewery, Cosmetic, Dairy, Food Industries.
