Coilhose Pneumatics 90412 Coolant Hose 12 in 1/4 Id

Product Description

The COILHOSE PNEUMATICS 90412 is a 12-inch neoprene coolant hose designed for use in mist coolant systems on machine tools and CNC equipment. It measures 1/4 inch inside diameter and terminates with a 3/8-inch nozzle, connecting to the coolant supply via a 1/4-inch NPT threaded fitting. The neoprene construction resists oil-based and water-based coolants commonly used in metalworking applications. At 0.5 pounds, it is a lightweight, direct-replacement component suited for maintenance technicians and machine tool service professionals performing coolant line repairs or system reconfigurations.

This hose is intended for mist coolant systems found on lathes, milling machines, drill presses, and similar metalworking equipment. The 1/4-inch NPT thread is a standard size that fits widely across coolant manifolds and supply lines in shop environments. The 12-inch length provides enough reach for most nozzle positioning needs without excess slack. It is sold individually and is appropriate for both OEM replacement and aftermarket coolant system builds.

Key Features

• 12-inch hose length for flexible nozzle positioning on machine tools
• 3/8-inch nozzle diameter for directed coolant flow
• 1/4-inch inside diameter matches standard mist coolant system tubing
• Neoprene construction resists oil-based and water-based coolants
• 1/4-inch NPT threaded connection for broad fitment across coolant manifolds

Compatibility

Designed for use with mist coolant systems. The 1/4-inch NPT thread is a common standard in metalworking coolant supply lines and manifolds.

Installation Notes

Shut off coolant supply pressure before removing or installing any coolant hose. Hand-tighten the NPT fitting first, then use a wrench to achieve a leak-free seal without overtightening the threaded joint. Inspect adjacent hose connections and nozzle fittings for wear or leaks during replacement. Installation is typically performed by machine tool technicians or maintenance personnel familiar with coolant system plumbing.
