Midland Industries 73961 Hose Nipple 4in Hose Barb X Nptf Ss

Product Description

The MIDLAND INDUSTRIES 73961 is a 4-inch hose barb to 4-inch male NPTF hose nipple constructed from 304 stainless steel. It connects flexible hose assemblies to threaded pipe systems using a barbed end for hose retention on one side and a tapered NPTF thread on the other. The 4-8 thread designation indicates a coarse-pitch thread profile suited to high-engagement connections. At 7.45 pounds, this is a heavy-duty fitting sized for large-diameter fluid transfer lines. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting in demanding fluid handling systems where corrosion resistance and mechanical strength are required.

This hose nipple is suited for large-bore industrial plumbing, irrigation, and fluid transfer applications where a flexible hose must terminate into a rigid threaded pipe connection. The 304 stainless steel construction makes it appropriate for water service, mild chemical transfer, and outdoor installations where carbon steel fittings would corrode. It is typically installed in commercial or industrial settings rather than residential light-duty plumbing. The NPTF end provides a dry-seal thread connection that reduces reliance on additional thread sealant under proper makeup conditions.

Key Features

• 4-inch hose barb end secures large-diameter flexible hose without additional clamp hardware in many configurations
• 4-inch male NPTF thread provides a dry-seal tapered connection to female NPT or NPTF pipe fittings
• 304 stainless steel construction resists corrosion in wet, outdoor, and mildly corrosive service environments
• 4-8 coarse thread profile supports high-engagement makeup on large-diameter NPTF connections
• Heavy construction at 7.45 pounds reflects robust wall thickness appropriate for demanding fluid service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for large-diameter hose barb to NPTF threaded pipe assemblies in industrial and commercial plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC and local plumbing code requirements. Shut off and depressurize the fluid line completely before removing or installing any fitting. Inspect the mating female NPTF or NPT threads for damage before makeup. Apply thread sealant tape or compound to NPTF threads as required by the system fluid and code, and hand-tighten before applying wrench turns to achieve proper makeup without overstressing the fitting body.
