Internal and External Thread Copper Cap

Updated: 2026-07-21

Overview

Brass ferrule plugs with internal and external threads are specialized fittings designed to seal unused ports in fluid control systems. These plugs are widely used in hydraulic and pneumatic applications, providing a reliable and leak-proof solution. The dual-thread design allows for versatile installation, making them suitable for various system configurations. Constructed from high-quality brass, these plugs offer excellent corrosion resistance and durability. They are commonly found in industrial machinery, automotive systems, and plumbing setups. Their ease of installation and removal makes them a preferred choice for maintenance and system modifications.

Structure and Working Principle

The brass ferrule plug features a cylindrical body with internal and external threads, allowing it to connect securely to male or female threaded ports. The ferrule design ensures a tight seal by compressing against the connection point, preventing fluid leaks. The plug's threaded ends are precision-machined to match standard thread specifications, ensuring compatibility with a wide range of systems. When installed, the plug blocks the flow of fluids or gases, effectively sealing off unused ports. This prevents contamination, pressure loss, and potential damage to the system. The brass material provides additional strength and resistance to wear, making these plugs suitable for high-pressure environments.
