Dixon Valve Coupling DV-00187 Venting Hose Coupling

Product Description

The DIXON VALVE COUPLING DV-00187 is a venting pneumatic hose coupling designed for use in compressed air and pneumatic fluid transfer systems. Built from steel with a nickel finish, this coupling features a 3/4-inch NPT threaded connection and is rated for a maximum working pressure of 150 psi. The venting coupling design allows pressure to safely bleed off during disconnection, reducing risk of hose whip and uncontrolled line pressure. This type of fitting is installed by industrial maintenance technicians, pipefitters, and pneumatic system service professionals in shop and field environments.

This coupling is suited for use in pneumatic tool lines, compressed air distribution systems, and general industrial hose assemblies where a venting-style disconnect is required. The 3/4-inch NPT thread size accommodates standard pipe thread connections common in industrial and commercial pneumatic setups. This part is sold in a package quantity of two, making it practical for paired coupling installations or replacement stock. It is appropriate for both new installations and maintenance replacement applications in shop air systems and similar environments.

Key Features

• Venting coupling design relieves line pressure at disconnection to reduce hose whip hazard
• 3/4-inch NPT thread for compatibility with standard industrial pipe thread fittings
• Steel construction with nickel finish for corrosion resistance in shop environments
• 150 psi maximum working pressure rating suitable for typical compressed air systems
• Sold in a package of two units per order

Compatibility

Designed as an OEM-style venting pneumatic hose coupling for use with 3/4-inch NPT threaded pneumatic hose assemblies and compressed air distribution fittings in standard industrial applications.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Always depressurize and isolate the air supply line completely before removing or installing any hose coupling. Apply thread sealant appropriate for pneumatic service to NPT threads per manufacturer and applicable code guidance. Inspect mating hose ends and fittings for wear or damage before making up connections.
