The 6C-LN, 6D-LN, and SV straight-through plate couplings are high-performance solutions for industrial fluid systems, built to excel in high-pressure and diverse operational scenarios—from hydraulic machinery to oil/gas processing.
At their core is an internal 24° cone seal, ensuring leak-proof connections even amid pressure and temperature fluctuations, a critical feature for avoiding costly fluid loss. Both ends have metric male threads, enabling seamless compatibility with global metric fluid components, simplifying installation and reducing the need for custom adapters.
These couplings offer three versatile end connections, all compliant with DIN3861/ISO8434 standards. Formed pipe ends optimize flow efficiency for space-constrained setups; welded pipe ends deliver maximum strength to withstand vibration in heavy-duty environments like mining; ferrule connections allow quick, tool-assisted assembly, ideal for systems needing frequent maintenance.
They fit two DIN2353-compliant 24° cone connection ranges: 06L-42L (light) for weight-efficient applications like automation, and 06S-38S (heavy) for durable use in large-scale manufacturing.
With a maximum pressure rating of 630bar (9,000 PSI), they thrive in high-stakes systems where standard couplings fail. Merging reliability, global compatibility, and robust performance, these couplings are a trusted choice for high-performance fluid system connections.
