REDUCER ELBOW(RLB)

Product Overview

The 90° Threaded Reducer Elbow (RLB) is a precision-engineered pipe fitting designed to create a 90-degree directional change while seamlessly transitioning between different pipe diameters in fluid piping systems.

This dual-function fitting combines right-angle flow redirection with size reduction, making it an essential component for optimizing pipeline layouts, connecting mismatched pipe sizes, and adapting to space-constrained installations.

Manufactured via advanced lost wax casting, it delivers exceptional dimensional accuracy, corrosion resistance, and mechanical strength for reliable long-term operation across diverse industrial applications.

Key Features

Dual-Function Reducing Design
Integrates a 90° elbow with a reducing connection, enabling simultaneous flow direction change and pipe size transition. Reduces the need for multiple fittings and simplifies installation.

Premium Material Selection
Available in stainless steel, carbon steel, alloy steel, tool steel, and custom alloys. Suitable for high-pressure, high-temperature, and corrosive environments.

Precision Lost Wax Casting Process
Ensures smooth internal surfaces, precise dimensions, and consistent mechanical properties, minimizing flow resistance and ensuring reliable sealing performance.

Global Standard Compliance
Complies with ASTM, JIS, DIN, BS, NF, ISO4144, SP-114, and K-version standards.
Full size range from 1/8" to 4", covering various reducing pipe combinations.

Secure Female Threaded Connection
Internal threaded design allows easy installation and disassembly, providing a tight, leak-proof connection for maintenance and retrofitting.

Customizable Surface Treatment
Supports passivation, polishing, coating, and other treatments to improve corrosion resistance, appearance, and service life.
