UNION M/F(CU MF)

Product Overview

The Stainless Steel Union M/F (CU MF) is a precision-engineered male-to-female threaded pipe union, designed for fast, detachable connections in fluid piping systems.

This versatile union allows easy assembly and disassembly without rotating the pipes, making it an essential component for industrial, commercial, and residential pipelines.

Manufactured via advanced lost wax casting, it ensures exceptional dimensional accuracy, corrosion resistance, and reliable sealing performance for long-term, leak-free operation.

Key Features

Male-to-Female (M/F) Detachable Union Design
Designed for convenient connection and disconnection between male and female threaded pipes. Eliminates the need for extra adapters, reduces potential leak points, and simplifies installation in space-constrained or retrofit piping layouts.

Premium Material Selection
Available in stainless steel, carbon steel, alloy steel, tool steel, and custom alloys. Suitable for high-pressure, high-temperature, and corrosive environments.

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

Global Standard Compliance
Complies with ASTM, JIS, DIN, BS NF, ISO4144, and K-version standards.
Complete size range from 1/8" to 4" for diverse pipeline applications worldwide.

Reliable Sealing Performance
Precision-engineered mating surfaces and a heavy-duty hex nut structure provide a tight, leak-proof seal under varying pressure and temperature conditions.

Customizable Surface Treatment
Supports passivation, polishing, coating, and other treatments to enhance corrosion resistance, aesthetics, and service life.
