Elbow Outlets | MSS SP-97 Branch Connection Fittings | Stainless Steel, Carbon Steel, Duplex & Nickel Alloy Elbow Outlets
Elite manufactures and supplies high-quality Elbow Outlets for industrial piping systems requiring a reinforced branch connection on a pipe elbow. Also known as Elbolets, these fittings are designed for installation on compatible elbow configurations, particularly 90° long-radius elbows, where a branch connection is required without using a conventional tee arrangement.
Elite offers Elbow Outlets in carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys and other project-specified materials. Designed for industrial piping applications, these fittings can be supplied with butt-weld, socket-weld or threaded branch connections, subject to the applicable design and customer requirements.
Our Elbow Outlets are used in oil and gas, petrochemical, chemical processing, power generation and other industrial applications. Material selection and outlet geometry can be specified according to operating conditions, corrosion requirements, temperature, pressure and project standards.
