HEX BUSHING (HB)

Product Overview

The Hex Bushing (HB) is a precision-engineered male-to-female threaded pipe fitting designed to reduce pipe size and create a secure, compact connection between mismatched threaded pipes in fluid piping systems.

Featuring a hexagonal head for easy tool tightening, this bushing enables seamless size transition, eliminates the need for multiple adapters, and simplifies installation across industrial, commercial, and residential piping networks.

Manufactured via advanced lost wax casting, the HB bushing provides exceptional dimensional accuracy, corrosion resistance, and reliable sealing performance for long-term, leak-free operation in a variety of fluid transfer applications.

Key Features

Hexagonal Head Design
The integrated hex head allows a secure, tool-friendly grip for easy installation and tightening, ensuring a tight, leak-proof seal without damaging the fitting body.

Male × Female Reducing Configuration
Combines an external male thread and an internal female thread, enabling direct connection between pipes of different diameters. Reduces potential leak points and simplifies pipeline layout.

Premium Material Options
Available in stainless steel, carbon steel, alloy steel, tool steel, and custom alloys, designed 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. Minimizes flow resistance while maintaining consistent product quality.

Global Standard Compliance
Fully compliant with ASTM, JIS, DIN, BS NF, ISO4144, SP-114, K-version standards. Covers a complete size range from 1/8" to 4", accommodating common reducing pipe size combinations worldwide.

Diverse Custom Surface Treatments
Available finishing options include polishing, electroplating, wire drawing, electrodeposition, powder spraying, oil spraying, blackening, passivation, dacromet plating, and electroless nickel deposition to meet corrosion resistance, aesthetic, and application requirements.

OEM/ODM Support
Custom manufacturing services are available for non-standard sizes, reducing ratios, materials, and surface treatments to meet unique project specifications.
