Hydraulic and pneumatic systems rely on durable and precise fittings to ensure smooth operation. One of the most important components is the threaded sleeve, also known as a coupling nut. These precision hardware parts connect pipes, tubes, or machinery elements with high accuracy, providing leak-proof performance and long-lasting durability.
A threaded sleeve is a cylindrical metal connector with internal threading designed to join pipes, rods, or components in hydraulic and pneumatic systems.
Threaded sleeves ensure:
Secure connection
Easy assembly/disassembly
High resistance to pressure and vibration
Stainless Steel – corrosion resistance, high strength
Aluminum Alloy – lightweight and durable
Brass – excellent machinability, anti-rust performance
Polished finish for smooth installation
Anodizing for corrosion protection
Heat treatment for higher wear resistance
Cylindrical body with inner thread
Hexagonal or round external shape for tool grip
Available in multiple diameters and lengths
High-pressure pipeline connections
Cylinder component assembly
Industrial machinery connections
Air compressors and valves
Pneumatic automation equipment
Robotics applications
Automotive components
