SS End Caps & Stub Ends

Raj Metals is a leading manufacturer of Stainless Steel Pipe End Caps and Stub Ends, engineered to meet the stringent demands of critical industrial piping environments. Our End Caps provide a robust, leak-proof solution for terminating pipelines, effectively protecting systems from internal pressure, debris, and external contaminants. For systems requiring frequent maintenance and simplified bolt-hole alignment, our Stub Ends (available in both Long and Short patterns) are designed to work seamlessly with Lap Joint flanges, offering a highly flexible and cost-effective connection. Precision-formed from stainless steel—such as 304L and 316L—these fittings ensure maximum structural integrity and superior corrosion resistance, making them the preferred choice for demanding chemical processing, oil & gas, and offshore infrastructure projects.

✓ Reliable Pipeline Termination for Permanent or Temporary Service (End Caps)

✓ Optimized Bolt-Hole Alignment with Lap Joint Flanges (Stub Ends)

✓ Exceptional Wall Thickness Consistency & High-Pressure Containment
