Midwest Fasteners Solid Brass Threaded Union Fitting

Midwest Fasteners Solid Brass Threaded Union Fitting

The Midwest Fasteners Solid Brass Threaded Union Fitting is a family of solid brass union fittings built for joining two sections of threaded pipe or tube where a serviceable disconnect point is needed without cutting the line. This union family is available in equal-size threaded connections ranging from 3/16" x 3/16" up to 3/8" x 3/8", including 1/4" x 1/4" and 5/16" x 5/16" options, so maintenance techs and fabricators can match the exact thread size required for their pipe run. Machined from solid brass across every size in the lineup, these unions provide a durable, corrosion-resistant connection point that stands up to repeated assembly and disassembly in plumbing, hydraulic, and general fluid-handling systems. The threaded connection allows each fitting to be installed and removed with standard wrenches, making this union family a practical choice for a reliable service or shutoff point in a pipe run.

Key Features

• Size Range: Available in equal-size threaded connections from 3/16" x 3/16" through 3/8" x 3/8", including 1/4" x 1/4" and 5/16" x 5/16", for matching two equal-size threaded lines.
• Material: Solid brass construction across the entire size range for corrosion resistance and long service life in plumbing and fluid-handling applications.
• Connection Type: Threaded ends allow installation and removal with standard pipe wrenches, no soldering or solvent welding required.
• Fitting Type: Union-style design creates a serviceable disconnect point in a pipe run for maintenance, repair, or component replacement.
• General-Purpose Brass Fitting: Suited for a range of threaded pipe and tube assemblies where a brass fitting is specified, across every size in the family.
• Consistent Thread Tolerances: Each union, regardless of size, is manufactured to consistent dimensional tolerances so it threads cleanly onto matching pipe or fitting threads without binding or leaking under normal working pressure.

Technical Specifications

• Refer to manufacturer documentation for complete technical specifications.

Typical Applications

• Residential and light commercial plumbing repairs where a union disconnect point is needed.
• Joining threaded brass, steel, or compatible pipe sections of matching thread size.
• Fluid-handling and hydraulic lines where brass corrosion resistance is preferred over steel.
• Equipment maintenance where a line must be periodically disconnected for service.
• General fabrication and shop plumbing tasks requiring a durable threaded union in a specific small-bore size.
