Malleable Reducer & Bushing Fittings

🔹Malleable Reducer & Bushing Fittings

Product Overview

Malleable Reducers and Bushings are critical components for connecting pipes of different diameters in low and medium pressure piping systems. They provide secure, leak-free joints while ensuring smooth flow transition and mechanical reliability.

Manufactured from high-quality malleable iron and produced according to EN 10242, ISO 49, ASTM A197, BS 143 / 1256, and GOST standards, these fittings combine strength, ductility, and corrosion resistance for long-term performance in industrial pipelines.

Available in Concentric and Eccentric Reducers as well as Bushing (internal/external) configurations, these fittings suit diverse piping layouts and design requirements.

Key Features & Advantages

Efficient Diameter Transition

  • Reducers – connect pipes with different diameters, available in concentric (center-aligned) and eccentric (offset) types for level or sloped pipelines.

  • Bushings – female-to-male threaded inserts for precise internal or external diameter adjustment.

High Mechanical Strength

Forged malleable iron construction withstands internal pressure, vibration, and external mechanical stress, ensuring durability under demanding conditions.

Leak-Free Performance

Precision-machined threads and consistent tolerances provide tight engagement, minimizing leakage risk and ensuring system reliability.

Versatile Installation

Suitable for horizontal and vertical pipelines, retrofit projects, and modular piping systems. Concentric and eccentric designs allow optimization of flow and prevent air/gas pockets in sloped lines.

Corrosion Resistance

Black, galvanized, or zinc-plated coatings provide protection for indoor and outdoor applications.

Materials & Manufacturing

  • Malleable Iron (ASTM A197 / EN 10242)

  • Forged or cast with heat treatment for ductility
