Domax Manufacturer is a trusted India-based producer, exporter, and supplier of premium-quality, high-performance stub end (lap joint) fittings. We provide products in a wide range of material grades, all manufactured in accordance with international dimensional standards. Our stub ends are available in both standard and customized ANSI dimensions, with options in seamless and lap joint (welded) forms across stainless steel, carbon steel, alloy steel, and nickel alloy materials.
Stub ends serve as an alternative to fixed welded flanges, especially where a rotating backup flange is required. They are typically paired with standard lap joint flanges for greater flexibility during installation and maintenance.
At Domax Manufacturer, we deliver stub ends suitable for diverse industrial applications, including nuclear, thermal, and hydel power plants, captive power units, oil & gas industries, refineries, petrochemical complexes, fertilizer and mineral units, mining, construction, steel production, shipbuilding, paper mills, pharmaceutical plants, and various pipeline projects.
