Loc-Line 1/2″ Modular Coolant Hose Assembly Kit — 50813
Part No: 50813 | Barcode: 662633508133 | Brand: Loc-Line
The Loc-Line 50813 is a complete starter kit for the 1/2″ ID modular coolant hose system. It contains everything needed to assemble a basic adjustable coolant line for lathes, mills, drill presses, grinders and bandsaws — segmented hose, round nozzles and NPT thread fittings — all moulded from durable acetal copolymer.
Compatible Applications
What’s in the Kit
- 2 × 1/2″ hose segments — each 5-1/2″ long, click together to set the desired length and shape.
- 1 × 1/4″ round nozzle — concentrated stream for tight spots and finish cuts.
- 1 × 3/8″ round nozzle — balanced flow for most lathe and mill work.
- 1 × 1/2″ round nozzle — high-volume flow for heavy roughing and chip flushing.
- 1 × 3/8″ NPT male connector — threads into 3/8″ pipe thread pump outlets.
- 1 × 1/2″ NPT male connector — threads into standard 1/2″ pipe thread coolant manifolds.
Key Features & Benefits
- Stays where you put it — the segmented ball-and-socket design holds any shape under coolant pressure, so you set the nozzle once and it stays aimed at the cut.
- Reshape by hand in seconds — no tools needed to add segments, change nozzles or redirect flow between jobs. Pull segments apart and click new ones in.
- Acetal copolymer construction — resistant to most water-soluble and synthetic cutting fluids, light machine oils and general workshop chemicals. Won’t rust, dent or kink.
- Threads into standard pipe — NPT male fittings included thread directly into your machine’s coolant pump outlet or manifold tap.
- Fully expandable — every component is interchangeable with the wider Loc-Line 1/2″ system, so you can extend length, add Y-splitters, valves, flat nozzles or magnetic bases later.
