Midland Industries CNTB-400CR-SS316 Turnback Nipple 4in Ss

Product Description

The MIDLAND INDUSTRIES CNTB-400CR-SS316 is a Crimplok Turnback Nipple designed for industrial hose assemblies requiring a secure, permanent crimp connection. Constructed from 316 stainless steel, this fitting delivers excellent corrosion resistance in demanding fluid-transfer applications. The 4-inch barbed end locks into the hose bore during crimping, and the 316 SS retainer provides added mechanical retention at the crimp zone. At 5.75 pounds and measuring approximately 6.95 inches in height and 6.15 inches in length and width, it is a robust, full-size fitting suited for high-flow industrial lines. Licensed plumbers and industrial pipefitters are the primary installers.

This fitting is used in industrial hose assemblies where a permanent, high-integrity crimp termination is required. Typical applications include bulk fluid transfer, chemical handling, and process piping where 316 stainless steel is specified for its resistance to chlorides and corrosive media. The 4-inch nominal size makes it appropriate for large-diameter hose in commercial and industrial settings. It falls within the Crimplok Combination Nipples product family, specifically the 150 lb flange 316SS retainer series, and is intended for professional installation using compatible crimping equipment.

Compatibility

Designed for use with large-diameter industrial hose assemblies requiring a 4-inch Crimplok-style crimp termination and a 150 lb flange 316SS retainer configuration. Consult manufacturer documentation to confirm compatibility with specific hose inner diameters and crimp specifications before installation.

Installation Notes

Installation requires compatible industrial crimping equipment rated for 4-inch hose fittings and should be performed by a qualified pipefitter or hose assembly technician. Depressurize and drain the line completely before removing any existing fittings. Verify that the hose inner diameter and wall construction are compatible with the barbed crimp profile before assembly. Follow applicable industry standards and the fitting manufacturer's crimp specifications to achieve a safe, leak-free connection.
