Stainless Steel Pipe Caps

Stainless steel pipe caps are essential fittings designed to seal the ends of pipes, preventing leakage, contamination, and mechanical damage. Crafted from premium 304, 316, or 316L stainless steel, these caps deliver exceptional corrosion resistance, high-temperature tolerance (-196°C to 800°C), and pressure durability, making them ideal for demanding industries like oil and gas, chemical processing, pharmaceuticals, food production, and marine engineering.
