Midland Industries 28057 Brass Pipe Coupling Nptf

Product Description

The MIDLAND INDUSTRIES 28057 is a brass pipe coupling designed for joining two 1/16-inch female NPTF threaded connections in pressurized fluid and gas piping systems. Built from solid brass, this compact fitting measures 0.65 inches in length with a 0.44-inch hex and a 1/16-27 thread specification. It carries a rated working pressure of 1200 psi and operates across a wide temperature range of -65 to 250 degrees F. Plumbers, pipefitters, and mechanical contractors install this type of fitting when making inline connections in tight-clearance assemblies where a full-size coupling is impractical.

This coupling is suited for residential and light commercial plumbing, hydraulic, pneumatic, and instrumentation applications where small-diameter NPTF connections are required. Its brass construction resists corrosion in both wet and dry service environments. The NPTF thread form creates a pressure-tight mechanical seal without requiring sealant tape in many installations, though thread sealant is commonly applied as a best practice. The fitting is appropriate for use in fuel, water, air, and oil service lines within its rated pressure and temperature limits.

Key Features

• 1/16-inch Female NPTF on both ends for inline pipe joining
• Rated to 1200 psi working pressure
• Operating temperature range: -65 to 250 degrees F
• Brass construction for corrosion resistance in wet and dry service
• 1/16-27 thread form for a reliable pressure-tight connection
• Compact 0.44-inch hex for installation in tight spaces

Compatibility

Rated for use with aluminum, brass, bronze, copper, iron, and steel pipe in systems requiring 1/16-inch Female NPTF threaded connections.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters in accordance with applicable mechanical codes. Shut off and depressurize the line completely before removing or installing any fitting. Use an appropriately sized wrench on the hex flats to avoid deforming the fitting body. Thread sealant or PTFE tape is commonly applied to NPTF joints as a supplemental measure, particularly in gas or hydraulic service.
