Fluid Line Products” Uniport 10K port/fitting system features a double seal, a metal-to-metal cone seal and radial o-ring, providing added reliability and security against a potential leak. Zero gap realized by cold deformation of the bottom of the cone prevents the o-ring from extruding at extremely high pressures. The swivel nut feature allows for selected positioning, closer ports, and smaller component size. Materials of construction include steel, stainless, brass, and Monel. Sizes range from 1/4″ to 1.5 inches.
