REDUCER HEX NIPPLE(RHN)

Product Overview

The Reducer Hex Nipple (RHN) is a precision-engineered double male threaded reducing pipe fitting with a central hexagonal head, designed for secure, tool-friendly connection of two female-threaded pipes of different diameters in fluid piping systems.

This dual-function fitting combines a straight hex nipple with a reducing configuration, enabling seamless size transition, eliminating the need for extra adapters, and simplifying installation in industrial, commercial, and residential piping networks.

Manufactured via advanced lost wax casting, the RHN delivers exceptional dimensional accuracy, corrosion resistance, and mechanical strength for long-term, leak-free operation across diverse fluid transfer applications.

Key Features

Hexagonal Head Design
The integrated central hex head provides a secure, tool-accessible grip for easy installation and tightening, ensuring a consistent, leak-proof seal without damaging the fitting body, even in tight spaces.

Dual Male Reducing Configuration
Features full external male threads on both ends with different diameters, enabling direct connection between two mismatched female-threaded pipes. Reduces potential leak points and streamlines pipeline layout.

Premium Material Selection
Available in stainless steel, carbon steel, alloy steel, tool steel, and custom alloys. Engineered to withstand high pressure, high temperature, and corrosive working environments.

Precision Lost Wax Casting Process
Ensures smooth internal surfaces, tight dimensional tolerances, and uniform mechanical properties, minimizing flow resistance and ensuring consistent product quality.

Global Standard Compliance
Compliant with ASTM, JIS, DIN, BS NF, ISO4144, and K-version standards. Covers a full size range from 1/8" to 4", suitable for all common reducing pipe size combinations for international projects.

Customizable Surface Treatment
Surface finishing can be fully customized, including passivation, polishing, coating, and more, enhancing corrosion resistance, aesthetics, and service life.
