Is the Narrow-Bore Flat Coolant Nozzle, 1/2" LOC-LINE® System compatible with other 1/2" coolant hose brands?

Narrow-Bore Flat Coolant Nozzle, 1/2" LOC-LINE® System Format: The nozzle is specifically designed for seamless integration with the LOC-LINE® 1/2" coolant hose system. While it may physically fit other 1/2" coolant hose brands that use the same nominal connection dimensions, compatibility is not guaranteed. Performance depends on exact inner/outer diameters, tolerances, and connection geometry of the alternate hose. Using non-LOC-LINE® hoses can lead to poor sealing, leaks, reduced pressure performance, misalignment, or premature wear. For reliable sealing, optimal fluid distribution and the rated working pressure (up to 2 bar) and temperature resistance, we recommend using this nozzle with the LOC-LINE® 1/2" system or verifying precise dimensional compatibility and material compatibility with the other brand before use.

Can the Narrow-Bore Flat Coolant Nozzle, 1/2" LOC-LINE® System handle higher-viscosity coolants or oils without affecting flow distribution?

Narrow-Bore Flat Coolant Nozzle, 1/2" LOC-LINE® System Format — Yes, within limits. The nozzle’s precision-engineered holes (5 or 7 openings, Ø 3.2 mm or Ø 2 mm), optimized flat geometry and durable acetal construction promote uniform flow even when using slightly higher-viscosity coolants or oils. However, performance depends on fluid viscosity relative to water, system pressure (max recommended 2 bar) and operating temperature (up to +76°C). Higher-viscosity fluids increase resistance through the small orifices and can reduce flow rate and spray pattern fineness; at or below the 2 bar rating the nozzle will generally maintain acceptable distribution for moderately thicker fluids, but very viscous oils may cause uneven flow, reduced coverage or require higher pressure to compensate — which risks exceeding the recommended working pressure. Practical guidance: for thicker coolants test at intended pressure and temperature, consider the larger hole size (Ø 3.2 mm) and the 5-hole variant for slightly better flow, and monitor tool temperature and chip evacuation. For consistently high-viscosity fluids, evaluate a nozzle with larger ports or a system capable of higher pressure.
