Slip On Flange
Product Details
Product Introduction
Slip On Flange from Leadtek Fluid is engineered for reliable pipe connection across a wide range of industrial systems. Hub slip-on flange designs feature an extended bore that allows the pipe to slip through before welding, providing dual weld points - one at the bore and one at the flange face - for enhanced joint strength and leak-tight performance under sustained operating pressure.
