Midland Industries CNG-400CR-SS316 Combination Nipple 4 in

Product Description

The MIDLAND INDUSTRIES CNG-400CR-SS316 is a Crimplok combination nipple designed for industrial and commercial hose assembly applications. It features a 4-inch hose barbed end on one side and a 4-inch grooved end on the other, allowing a direct transition between a crimped hose connection and a grooved-pipe coupling in a single fitting. Constructed from 316 stainless steel, this nipple resists corrosion in demanding fluid-handling environments. It is installed by plumbers, pipefitters, and fluid system technicians working on medium-to-large diameter hose assemblies where a grooved mechanical joint is required at the pipe end.

This fitting is suited for use in industrial process piping, commercial plumbing, and fluid transfer systems where 4-inch hose lines must terminate at a grooved-end connection. The hose barb end is designed to be secured with CRIMPLOK ferrules, specifically the CF-XXXXX-SP series, making it compatible with standard Crimplok hose assembly tooling and ferrule stock. It is appropriate for both new installations and retrofit work on existing grooved piping systems.

Key Features

• 4-inch hose barb end accepts crimped hose assemblies secured with CRIMPLOK CF-XXXXX-SP ferrules
• 4-inch grooved end connects directly to grooved-pipe couplings such as Victaulic-style fittings
• 316 stainless steel construction provides superior corrosion resistance compared to 304 or carbon steel alternatives
• Combination design eliminates the need for an additional adapter between the hose end and grooved piping
• Single-piece construction reduces potential leak points in the assembly

Compatibility

Designed for use with CRIMPLOK ferrules CF-XXXXX-SP. The grooved end is compatible with standard grooved-pipe couplings for 4-inch pipe. Verify coupling groove dimensions against your system standard before installation.

Installation Notes

Installation of grooved-end fittings and crimped hose assemblies should be performed by a qualified pipefitter or plumber familiar with grooved mechanical joint systems. Depressurize and drain the line completely before disconnecting or installing any hose fitting. Use the appropriate Crimplok crimping tool and inspect the ferrule seating before pressurizing the assembly. Follow applicable codes including ASME B31.3 for process piping or local plumbing codes as required by the installation environment.
