Midland Industries 700082-0504 Reducing Compression Union

Product Description

The MIDLAND INDUSTRIES 700082-0504 is a reducing compression union designed to join two different-diameter tubing runs in a single inline connection. It accepts a 5/16-inch compression fitting on one end and a 1/4-inch compression fitting on the other, allowing a field technician to transition between tubing sizes without soldering or threading. The body is manufactured from lead-free brass, making it suitable for potable water and refrigerant line applications where lead-free compliance is required. Rated for service from -40 degrees F to 250 degrees F, this fitting handles a wide range of operating temperatures encountered in plumbing, HVAC, and refrigeration work.

This fitting is a standard inline reducer used in residential and light commercial applications where copper, aluminum, or plastic tubing sizes need to be matched at a junction point. Typical scenarios include connecting two tubing segments of differing diameters on water supply lines, ice maker lines, and pneumatic or refrigeration tubing runs. It is installed by plumbers, HVAC technicians, and refrigeration mechanics working on systems that require a compression-style transition fitting.

Key Features

• 5/16-inch compression inlet to 1/4-inch compression outlet for inline size reduction
• Lead-free brass construction meets lead-free compliance requirements for potable water service
• Compatible with copper, aluminum, and plastic tubing
• Temperature range of -40 degrees F to 250 degrees F suits a broad range of applications
• Compression-style connection requires no soldering, threading, or special tools

Compatibility

Compatible with copper, aluminum, or plastic tubing. Designed as an OEM-style replacement or new-installation compression union for plumbing, HVAC, and refrigeration tubing systems requiring a 5/16-inch to 1/4-inch size transition.

Installation Notes

Installation is performed by a licensed plumber or HVAC-refrigeration technician. Shut off the water supply or isolate the refrigerant circuit and relieve system pressure before disassembling any tubing connections. Ensure tubing ends are cut cleanly and deburred before seating the compression ferrule to achieve a leak-free joint. Verify local plumbing codes and applicable IPC requirements for approved fitting materials and installation methods in your jurisdiction.
