Midland Industries CNG-300-SP Combination King Nipple

Product Description

The MIDLAND INDUSTRIES CNG-300-SP is a combination king nipple designed to transition between a hose barbed connection and a grooved-end connection within fluid-handling and industrial piping systems. Built from plated steel, this fitting provides a reliable mechanical joint for applications where a hose assembly meets a grooved-end pipe or coupling. Both connection ends are sized at 3 inches, making this a true same-size transition fitting. Plumbers, pipefitters, and mechanical contractors working on industrial or commercial installations are the primary trades that specify and install this type of fitting.

This combination king nipple is suited for use in industrial fluid-transfer, fire protection, and mechanical piping systems where hose barb assemblies tie into grooved-end piping networks. The grooved end is designed to interface with standard grooved couplings in the Victaulic-style product category. A minimum order quantity of one unit makes this fitting accessible for single-unit replacement or project-specific procurement. It is catalogued under combination king nipples in the hose fittings section, consistent with plated steel grooved-end product lines.

Key Features

• 3 inch hose barbed end for secure hose assembly attachment
• 3 inch grooved end compatible with standard grooved-end couplings
• Plated steel construction for corrosion resistance in demanding environments
• Same-size 3 inch x 3 inch configuration eliminates reducing fittings in the line
• Classified under grooved-end Victaulic-style plated steel fittings category

Compatibility

Designed as an OEM-style replacement or new-installation fitting for grooved-end piping systems using standard Victaulic-style couplings, paired with 3 inch hose assemblies in industrial or commercial mechanical piping applications.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical and plumbing codes. Depressurize and drain the system fully before removing or installing any fitting. Inspect the grooved-end pipe for proper groove depth and width before seating the coupling to ensure a leak-free joint. Verify that the hose barb is fully engaged and properly clamped to the hose before returning the system to service.
