Loc-Line Modular Coolant Hose Systems — Segments, Nozzles & Assembly Kits

Loc-Line is the original modular hose system, trusted by machinists, toolmakers and CNC operators worldwide for precise coolant and air delivery at the cutting zone. The snap-together ball-and-socket design allows the hose to be positioned and repositioned by hand without tools, holding its position under coolant pressure and vibration. Available in 1/4", 1/2" and 3/4" systems, Loc-Line is used on CNC machining centres, lathes, milling machines, surface grinders and manual machines wherever repeatable, directional coolant delivery is required. Black Loc-Line is frequently used in aquariams. AIMS Industrial sells an extensive range of Loc-Line assembly kits, individual segments, nozzles and connectors.

Loc-Line Assembly Kits & Segment Packs — 1/4", 1/2" & 3/4" Systems

Loc-Line assembly kits provide everything needed to build a complete coolant delivery system in one purchase — segments, manifold and nozzle — making them the fastest way to set up or replace a coolant line on a machine. Individual segment packs are the right choice when extending an existing system or replacing worn sections. The 1/4" system suits light-duty and small-bore coolant applications; the 1/2" system is the standard for most CNC machining centres; and the 3/4" system handles higher-flow requirements on larger machines.

• Loc-Line 1/4" Coolant Hose Assembly Kit: Complete 1/4" modular hose kit for light-duty coolant delivery on manual lathes, small CNC machines and bench grinders; includes segments, manifold and nozzle
• Loc-Line 1/2" Coolant Hose Assembly Kit: The most popular Loc-Line kit for CNC machining centres and lathes; standard 1/2" system with sufficient flow capacity for most water-soluble and oil coolant applications
• Loc-Line 3/4" Coolant Hose Assembly Kit: High-flow 3/4" modular hose kit for large CNC machines and high-volume coolant systems; same tool-free positioning as smaller systems with increased flow capacity
• Loc-Line 1/2" Segment Pack: Replacement or extension segments for existing 1/2" Loc-Line systems; snap together without tools for quick system modification or repair

Loc-Line Nozzles, Connectors, Shop Vacuum Kits & Tools

Beyond the core coolant hose range, Loc-Line offers a series of accessories that extend the system's utility in the workshop. Flat fan and round nozzles allow the coolant flow pattern to be matched to the cutting operation — flat fan for milling and surface grinding, round for turning and drilling. NPT and BSPT machine connectors allow the system to be connected to standard coolant pump fittings. The Shop Vacuum Kit adapts the Loc-Line modular system for use as a flexible vacuum hose on shop vacuum units, while the Loc-Line pliers make assembly and disassembly of tight joints straightforward.

• Loc-Line 1/2" Flat Fan Nozzle: Flat fan spray nozzle for 1/2" Loc-Line systems; provides wide, even coolant coverage across the cutting zone for milling and surface grinding operations
• Loc-Line 1/2" NPT Male Connector: NPT male fitting to connect Loc-Line 1/2" system to standard coolant pump outlets; provides a secure, leak-free connection at the machine's coolant supply point
• Loc-Line Shop Vacuum Kit 1-1/4": Modular shop vacuum hose kit using the Loc-Line snap-together system; positions and holds the vacuum inlet precisely without hose clamps or brackets
• Loc-Line Assembly/Disassembly Pliers: Purpose-made pliers for assembling and disassembling Loc-Line ball-and-socket joints; prevents damage to segments when separating tight connections
