Midland Industries LF62R-106 Reducing Union 5/8 X 3/8 Compression

Product Description

The MIDLAND INDUSTRIES LF62R-106 is a lead-free brass reducing union designed to join two different-diameter compression lines in a single inline connection. It accepts a 5/8-inch compression fitting on one end and a 3/8-inch compression fitting on the other, making it a practical solution wherever a diameter transition is required in a compression-fit tubing run. The 13/16-18 thread specification ensures consistent, leak-resistant engagement when properly installed. Rated for service from -40 degrees F to 250 degrees F, this fitting handles the thermal range common in refrigeration, HVAC, and plumbing applications. Licensed plumbers and HVAC technicians are the primary installers of this type of fitting.

This reducing union is suited for residential and light commercial applications where a compression-style connection is required between lines of differing outside diameters. It is compatible with copper, aluminum, and plastic tubing, giving installers flexibility across a range of system types. Typical install scenarios include refrigerant line transitions, potable water supply lines, and pneumatic or instrumentation tubing runs where a tool-free, re-workable joint is preferred over a soldered or flared connection.

Key Features

• Reduces from 5/8-inch compression to 3/8-inch compression in a single fitting body
• Lead-free brass construction meets requirements for potable water and plumbing code compliance
• Compatible with copper, aluminum, and plastic tubing types
• Rated from -40 degrees F to 250 degrees F for broad service range
• 13/16-18 thread for consistent, secure engagement
• Lightweight at 0.117 pounds - minimal load on tubing runs

Compatibility

Designed for use with copper, aluminum, or plastic tubing in compression-style fitting applications across HVAC, plumbing, and related trade installations.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local plumbing codes and the IPC where referenced. Shut off and depressurize the supply line fully before disassembling or installing any compression fitting. Ensure tubing ends are cut square and deburred before seating the compression sleeve to achieve a leak-free joint. Do not overtighten compression nuts - use a backup wrench on the fitting body to prevent body rotation and deformation of the sleeve.
