Midland Industries SS5000-16-08 Hex Pipe Coupling

Product Description

The MIDLAND INDUSTRIES SS5000-16-08 is a hex pipe coupling designed to join two female NPTF-threaded pipe sections of different sizes in a single inline connection. Built from 316 stainless steel, it handles demanding service conditions including pressures up to 4400 psi and temperatures up to 1000 degrees F. The reducing hex body gives wrenching flats for straightforward installation and removal. This fitting is appropriate for licensed plumbers, pipefitters, and mechanical contractors working on high-pressure fluid or gas distribution systems where corrosion resistance and thermal stability are critical requirements.

This coupling is suited for residential and commercial plumbing, hydraulic, pneumatic, and process piping applications where a 1-inch female NPTF port must be reduced to a 1/2-inch female NPTF port. Its 316 stainless steel construction makes it a practical choice for corrosive environments including marine, chemical processing, and food-service installations. The compact 1.129-inch body length allows installation in tight spaces with standard pipe wrenches or hex wrenches.

Key Features

• 316 stainless steel construction for excellent corrosion resistance in harsh and marine environments
• Rated to 4400 psi working pressure for high-pressure system service
• Temperature rating up to 1000 degrees F for high-heat process piping applications
• 1 in Female NPTF x 1/2 in Female NPTF configuration provides a reducing inline connection
• Thread spec 1-11-1/2 x 1/2-14 per NPTF standards for pressure-tight thread engagement
• Hex body profile allows positive wrench grip during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for high-pressure stainless steel pipe assemblies requiring a 1-inch female NPTF to 1/2-inch female NPTF reducing hex coupling.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and ASME B1.20.3 NPTF thread standards. Depressurize and isolate the line completely before disassembling any fitting in the system. Apply an appropriate thread sealant rated for the service fluid and temperature before assembly. Do not over-torque; hand-tighten first, then wrench-tighten to achieve a leak-free seal without stressing the fitting body.
