Coilhose Pneumatics 90818 Coolant Hose 18 in Neoprene

Product Description

The COILHOSE PNEUMATICS 90818 is an 18-inch neoprene coolant hose designed for mist coolant delivery in machining and cutting applications. The hose features a 1/2-inch inside diameter and a 1/2-inch NPT nozzle connection, providing a positive seal at the spray head without restricting flow. Neoprene construction offers resistance to oil, coolant fluid, and the moderate heat generated in close-proximity cutting environments. Licensed machinists and maintenance technicians install this hose as part of a mist coolant system to direct cutting fluid precisely to the tool-workpiece interface, reducing heat buildup and extending tool life.

This hose is suited for use in shop environments where mist coolant systems are mounted on CNC machines, mills, lathes, and similar metalworking equipment. The 1/2-inch NPT thread standard ensures compatibility with standard mist coolant nozzle assemblies and manifold fittings commonly found in production and job-shop settings. Its 18-inch length gives sufficient reach to position the nozzle at the cutting zone without excessive slack.

Key Features

• 18-inch hose length provides flexible reach to the cutting zone
• 1/2-inch inside diameter supports consistent mist coolant flow volume
• 1/2-inch NPT thread ensures a secure, leak-resistant connection to nozzle assemblies
• Neoprene construction resists oil, cutting fluids, and moderate heat exposure
• Sold individually — single-piece packaging suitable for replacement or system build-out

Compatibility

Designed for use with mist coolant systems equipped with 1/2-inch NPT fittings and nozzle assemblies. Verify thread size and inside diameter requirements before installation.

Installation Notes

Installation is typically performed by a machinist or maintenance technician. Shut off the coolant system and depressurize any supply lines before disconnecting or replacing the hose. Apply thread sealant rated for coolant service to the NPT connections and hand-tighten before final wrench snugging — do not overtighten, as NPT fittings can crack nozzle bodies if forced. Confirm no leaks are present under system pressure before returning the machine to service.
