The Stainless Steel Thread Hex Cap is a durable, user-friendly component designed to seal the ends of threaded piping systems, balancing leak-proof performance with easy maintenance. Manufactured from top-tier SS304, SS316, SS304L, or SS316L stainless steel, this hex cap features precision-engineered threads (compatible with NPT, BSPT, BSPP, and DIN standards) and a hexagonal design for tool-free installation/removal. Rated for 150# pressure, it caters to diverse applications—from construction and water treatment to medical equipment and chemical plants. Unlike permanent blind plates, the hex cap is fully detachable, making it perfect for systems requiring periodic inspection or modification. Available in sizes 1/8" to 4" (DN6 to DN100), it combines corrosion resistance, structural strength, and versatility to meet industrial and commercial piping needs.
