The 2-1/2 x Close 304 Stainless Steel Nipples is a short, threaded pipe fitting designed for connecting two female-threaded pipes or fittings in a tight space. Made from 304 stainless steel, it offers excellent corrosion resistance, making it ideal for high-pressure, high-temperature, and harsh environment applications. The heavy-duty industrial grade is suitable for high-pressure and high-temperature applications. The ""close"" designation means the nipple has minimal space between the threaded ends, allowing for a compact and secure connection.
