Malleable Nipple Fittings

🔹Malleable Nipple Fittings

Product Overview

Malleable Nipples are short threaded connectors designed to join two internally threaded pipes or fittings, enabling secure and leak-free connections in low and medium pressure piping systems.

Manufactured from high-quality malleable iron and produced in compliance with EN 10242, ISO 49, ASTM A197, BS 143 / 1256, and GOST standards, these nipples provide excellent mechanical strength, ductility, and long-term reliability in various industrial applications.

Available in Equal Nipple (same diameter on both ends) and Reducing Nipple (different diameters) configurations, Malleable Nipples are ideal for pipeline extension, repair, and system modification projects.

Key Features & Advantages

Secure and Leak-Free Connection

Precision-machined threads ensure tight engagement with mating components, providing reliable, leak-free performance.

High Mechanical Strength

Forged malleable iron construction resists internal pressure, vibration, and mechanical stress, ensuring long service life.

Flexible Design Options

  • Equal Nipple – standard pipe extension

  • Reducing Nipple – connecting pipes of different diameters

Easy Installation & Maintenance

Simple installation using standard tools, no welding required. Ideal for maintenance, retrofit, or modular piping systems.

Corrosion Resistance

Surface finishes include black, galvanized, or zinc-plated coatings for durability in indoor and outdoor environments.

Materials & Manufacturing

  • Malleable Iron (ASTM A197 / EN 10242)
