Key Features
Universal Hydraulic Connection Design
Designed for general hydraulic applications, providing a reliable connection solution for industrial equipment and mobile hydraulic systems.
Durable Ball Locking Mechanism
The ball-locking structure ensures secure engagement between coupling and nipple, improving connection stability during operation.
Hardened Components for Long Service Life
Both sleeve and nipple are hardened to improve resistance against brinelling, mechanical shock and repeated coupling cycles.
Reliable Poppet Valve Sealing
The captive valve seal is positively retained by the metal poppet, helping minimize seal washout and damage caused by high-velocity hydraulic fluid.
High Pressure Sealing Support
An optional PTFE support ring is available to improve sealing performance and reduce seal extrusion in high-pressure hydraulic environments.
Precision Machined Construction
The coupling and nipple are precision machined from solid bar stock to ensure consistent quality, strength and long-term reliability.
Applications
The KZE Universal Hydraulic Quick Couplings are suitable for:
- Construction machinery
- Agricultural equipment
- Industrial hydraulic systems
