Loc-Line 3/4" Modular Hose System
The 3/4" Loc-Line system is the high-flow option in the modular ball-and-socket coolant range, designed for larger CNC machining centres, big-bore lathes and grinding machines where the 1/2" system can't deliver enough volume. Typical use cases include flood coolant on large face mills, multi-spindle drilling heads, broaching machines, gear-cutting machines and any setup where the cutting zone needs more than the standard 1/2" line can supply. The larger bore drops pressure loss across the line while keeping the same tool-free snap-together assembly that makes Loc-Line the standard choice.
What's in the 3/4" range
The 21 products in this collection cover the core 3/4" system — flexible hose segments, hoses with integrated mounts, flat-fan and round nozzles sized for the higher flow rate, threaded connectors and fittings. The 3/4" range is more focused than the smaller systems because the application set is narrower — most workshops only need the 3/4" line on one or two large machines.
When to step down a size
If you're not certain you need the higher flow, the 1/2" Loc-Line system handles most CNC coolant applications and is significantly more popular. Adapters in the 3/4" range allow you to step down at the nozzle end if needed.

People Also Ask — 3/4" Loc-Line Modular Hose System
Q: When does a machine need the 3/4" Loc-Line system instead of the more common 1/2" system?
The 3/4" system is the high-flow option for larger CNC machining centres, big-bore lathes and grinding machines where the 1/2" line can't deliver enough coolant volume — the larger bore drops pressure loss across the line while keeping the same tool-free snap-together assembly.
Q: What kinds of machine setups actually need the 3/4" high-flow Loc-Line line?
Flood coolant on large face mills, multi-spindle drilling heads, broaching machines and gear-cutting machines are the typical use cases — situations where the cutting zone needs more coolant volume than a standard 1/2" line can supply.
Q: What's included in the 3/4" Loc-Line range?
21 products cover the core system — flexible hose segments, hoses with integrated mounts, flat-fan and round nozzles sized for the higher flow rate, and threaded connectors and fittings.
Q: Can a 3/4" Loc-Line line be stepped down to a smaller nozzle if the full flow isn't needed at the outlet?
Yes — adapters in the 3/4" range allow stepping down at the nozzle end, so the high-flow line can still be run to a smaller final nozzle where that suits the job.
Q: Why is the 3/4" Loc-Line product range narrower than the 1/2" system's?
The 3/4" application set is narrower than the 1/2" system's — most workshops only need the high-flow line on one or two large machines, so the range is more focused rather than covering the same breadth of fittings and accessories as the more popular smaller sizes.
