Midland Industries 700082-0402 Reducing Compression Union

Product Description

The MIDLAND INDUSTRIES 700082-0402 is a reducing compression union designed to join two different tubing sizes in a single inline connection. It accepts a 1/4-inch compression fitting on one end and a 1/8-inch compression fitting on the other, making it a practical solution when transitioning between tube sizes without soldering or threading. Constructed from lead-free brass, this fitting meets lead-free compliance requirements for potable water and other regulated systems. The operating temperature range spans -40 degrees F to 250 degrees F, giving it solid performance across refrigeration, HVAC, and plumbing applications. Licensed plumbers and HVAC technicians are the primary installers.

This reducing union is suited for residential and light commercial applications where copper, aluminum, or plastic tubing must be connected at different diameters. Common install scenarios include instrumentation lines, refrigerant sensing lines, water supply connections, and pneumatic control tubing. The compression-style ends eliminate the need for heat or solder, which is particularly useful in retrofit or service work where open flame is restricted or inconvenient. Its compact size makes it well-suited for tight spaces in mechanical rooms, utility chases, and equipment cabinets.

Key Features

• Reduces from 1/4-inch compression to 1/8-inch compression in a single fitting
• Lead-free brass construction meets regulatory requirements for applicable systems
• Rated for -40 degrees F to 250 degrees F operating temperature
• Compatible with copper, aluminum, and plastic tubing
• No soldering or threading required - compression ends only
• Compact profile fits confined mechanical spaces

Compatibility

Designed for use with copper, aluminum, or plastic tubing. Suitable as an OEM-style or service replacement reducing compression union in plumbing, HVAC, and instrumentation applications requiring a 1/4-inch to 1/8-inch diameter transition.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off the water or fluid supply and depressurize the line before beginning work. Hand-tighten the compression nuts, then use an appropriately sized wrench to snug the connection - do not overtighten, as this can deform the compression sleeve and cause leaks. Verify all connections for leaks after restoring system pressure.
