Euro Style Hydraulic Quick Couplings – KIS-HT Series
The Euro Hydraulic Quick Couplings from the POOLKE KIS-HT Series are designed for reliable hydraulic connection in mobile equipment, industrial machinery and general hydraulic applications requiring high flow performance and secure operation. Featuring a high-flow internal design, this series helps minimize pressure drop and improves hydraulic system efficiency during fluid transfer.
The KIS-HT Series is manufactured with nickel-plated steel coupling bodies and hardened nickel-plated steel nipples to provide excellent durability and resistance to mechanical impact. With a double O-ring sealing structure and sleeve lock mechanism, the Euro Hydraulic Quick Couplings deliver reliable sealing performance and help prevent unexpected disconnection during operation.
Key Features
High Flow Hydraulic Design
The optimized internal flow passage reduces pressure loss and improves fluid transfer efficiency, making it suitable for hydraulic systems requiring high flow rates.
Double O-Ring Sealing Structure
The double O-ring design provides enhanced sealing reliability and helps prevent hydraulic leakage during operation.
Sleeve Locking Mechanism
The sleeve lock structure improves connection security and helps prevent accidental disconnection caused by vibration or external impact.
Durable Nickel-Plated Steel Construction
The coupling body is manufactured from nickel-plated steel, while the nipple uses hardened nickel-plated steel to improve strength and wear resistance.
Hardened Components for Long Service Life
Both sleeve and nipple are hardened to resist brinelling, mechanical shock and repeated connection cycles.
Precision Machined Components
The coupling and nipple are precision machined from solid bar stock to ensure consistent dimensions and reliable performance.
Applications
The Euro Hydraulic Quick Couplings are suitable for:
- Construction machinery
- Agricultural machinery
- Industrial hydraulic systems
- Hydraulic power units
- Mobile hydraulic equipment
- General hydraulic applications
