45° Lateral Outlets | Forged Branch Connection Fittings | Carbon Steel, Stainless Steel & Alloy Steel Lateral Outlets | Industrial Piping Systems
Elite manufactures and supplies high-quality Lateral Outlets, also known as Latrolets, for industrial piping systems requiring a 45-degree branch connection from a main pipe. Designed for reliable branch connections, these fittings provide an engineered alternative to conventional lateral tees in applications where compact installation, branch reinforcement and piping layout flexibility are important.
Lateral Outlets are commonly used in oil and gas, petrochemical, chemical processing, power generation, offshore facilities and general industrial piping systems. Their angled branch configuration allows process flow to be diverted at approximately 45 degrees, supporting specialized piping arrangements and reducing the need for multiple fittings in suitable applications.
Elite supplies Lateral Outlets in carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys and other specialty materials. Available configurations include butt-weld, socket-weld and threaded branch connections, subject to applicable standards, design requirements and customer specifications.

| Note: Lateral Outlets are specialized 45° branch connection fittings. MSS SP-97 primarily addresses integrally reinforced forged branch outlet fittings, while ASME B16.11 covers forged socket-welding and threaded fittings. Applicability to a specific lateral outlet must be confirmed against its design and connection configuration. Non-standard 45° lateral outlets may require engineering calculations, approved drawings and additional design verification. | ||
