Flexible Coolant Pipe

Flexible coolant pipes (often called modular coolant hoses, loc-line hoses, or flexible nozzle pipes) provide precise, adjustable delivery of coolant, air or mist to the cutting zone. Made from durable, chemical-resistant polymers or braided flexible metal, these hoses allow operators to position coolant nozzles exactly where needed — improving chip evacuation, reducing heat, and extending tool life. Available in single-line and split-line configurations, with quick-connect fittings, directional nozzles, and ball-joint segments, flexible coolant pipes are ideal for CNC mills, lathes, drill presses, grinders and manual machines. These hoses support neat, repeatable coolant application for wet machining, MQL (minimum quantity lubrication), and air-blow operations. Their modular snap-together design makes adjustment, reconfiguration and replacement fast—minimizing downtime. Typical markets include automotive, tool & die, aerospace, fabrication and job shops where precise coolant placement improves surface finish, reduces cycle time, and prevents thermal distortion. Key Features Modular snap-together segments for infinite positioning. Materials: chemical-resistant acetal/nylon plastics, flexible stainless/steel braided options. Nozzle types: round, flat fan, mist, adjustable orifice. Sizes: typical hose diameters Ø6 mm to Ø16 mm (ID/OD depends on type). Quick-connect fittings: BSP/NPT/metric or push-fit for fast installation. Temperature resistance: typical −20°C to +120°C (varies by material). Pressure ratings: up to ~6–10 bar for plastic modular hoses; higher for metal braided types. Compatible with coolant, cutting oil, compressed air and light MQL fluids. Easy to cut and extend; replacement segments available. Typical Specifications (customize per SKU) Product Type: Modular flexible coolant pipe / loc-line hose / braided flexible hose Material: Acetal (POM) / Nylon / PTFE-lined / Stainless braided metal Inner Diameter (ID): 4 mm, 6 mm, 8 mm typical Outer Diameter (OD): 6 mm – 16 mm typical Working Pressure: 0.5 – 10 bar (check specific model) Temperature Range: −20°C to +120°C (model dependent) Fittings: BSP / NPT / Metric / Push-fit / Quick-connect Lengths: Modular segments (e.g., 25–50 mm per segment) — assembled lengths as required Nozzle Types: Round/flat/mist/air jet/adjustable orifice Benefits / Use Cases Accurate coolant targeting reduces tool wear and improves surface finish. Quick reconfiguration for different jobs — lowers setup time. Ideal for wet machining, grinding, EDM cooling, and MQL applications. Reduces splash and coolant waste by directing flow precisely. Prevents thermal distortion in precision components by controlled cooling. Installation & Maintenance Tips Flush hose before use to remove debris. Use correct pressure-rated hose for pressurized coolant systems. Replace worn nozzle segments; keep spare segments on the bench. For metal braided hoses, inspect for kinked or damaged braid regularly. Use compatible seals (Viton/NBR) when switching fluids.
