A stainless steel cap seals pipe ends to prevent contamination in aggressive environments. These stainless steel caps (ASME B16.9) work in oil/gas, food processing, and wastewater systems. With Ra ≤0.8μm mirror finishes, stainless steel caps meet sanitary standards.
Stainless steel caps come in 304L, 316Ti, and duplex grades, rated for temperatures from -196°C to 400°C. Their domed/hemispherical designs allow stainless steel caps to withstand 2,000+ psi pressure. Choose threaded or welded stainless steel caps for permanent/temporary closures.
