Dixon Valve Coupling 14255 Hose Nipple 1/8 Mnpt Steel

Product Description

The DIXON VALVE COUPLING 14255 is a steel pneumatic hose nipple coupling designed for compressed-air and pneumatic tool lines. It features a 1/8-inch male NPT thread and accepts hose with a 1/4-inch inside diameter. Rated to 600 psi maximum working pressure, this nipple-style coupling provides a reliable, leak-resistant connection point in pressurized pneumatic systems. Licensed plumbers, pipefitters, and pneumatic system technicians install this type of fitting as part of air supply infrastructure in both shop and field applications.

This coupling is suited for light-to-medium pneumatic circuits where a 1/8-inch MNPT port connects to 1/4-inch ID hose. Typical applications include air compressor outlet connections, pneumatic tool quick-connect setups, and inline distribution manifolds in residential and light commercial settings. The steel construction holds up to the cyclic pressure loads common in production and service environments. Sold in a package quantity of 10 units, making it practical for stocking service vehicles or shop parts bins.

Key Features

• 1/8-inch MNPT thread conforms to NPT thread standard
• Accepts 1/4-inch inside diameter pneumatic hose
• 600 psi maximum working pressure rating
• Steel construction resists deformation under cyclic load
• Packaged in quantities of 10 for bench stock or fleet use

Compatibility

Designed as an OEM-style replacement or service fitting for pneumatic hose assemblies using 1/4-inch ID hose and 1/8-inch MNPT threaded ports.

Installation Notes

Installation is typically performed by a pipefitter or pneumatic system technician. Depressurize the air supply line completely before removing any existing fitting or coupling. Apply thread sealant or PTFE tape to the male NPT threads per the fitting manufacturer and applicable piping code guidelines. Do not overtighten steel NPT fittings into cast or soft-metal ports, as this can crack the receiving fitting body.
