HEX NIPPLE(HN)

Product Overview

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

This robust fitting creates a straight, leak-proof joint, making it an essential component for industrial, commercial, and residential piping networks.

Manufactured via advanced lost wax casting, the Hex Nipple delivers exceptional dimensional accuracy, corrosion resistance, and mechanical strength for long-term, reliable 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.

Dual Male Thread Configuration
Features full external male threads on both ends, enabling direct connection between two female-threaded pipes. Eliminates the need for extra adapters and reduces potential leak points.

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 surfaces, tight dimensional tolerances, and uniform mechanical properties, minimizing flow resistance and maintaining consistent product quality.

Global Standard Compliance
Compliant with ASTM, JIS, DIN, BS NF, ISO4144, SP-114, K-version standards. Available in a full size range from 1/8" to 4", covering all common pipeline specifications for international projects.

Customizable Surface Treatment
Surface finishing can be customized per customer requirements, including passivation, polishing, coating, and more, enhancing corrosion resistance, aesthetic appearance, and service life.
