Usd Products 62-R-86 Compression Union 3/8 X 1/2 Inch

Product Description

The USD PRODUCTS 62-R-86 is a compression union fitting designed to join two sections of tubing with different outside diameters: 3/8 inch on one end and 1/2 inch on the other. Compression unions create a secure, leak-resistant connection without soldering or brazing, making them a practical choice for refrigerant lines, potable water supply lines, and other fluid-handling systems. Licensed plumbers and HVAC technicians install this type of fitting where a removable, re-serviceable joint is needed and open flame work is not permitted or practical.

This compression union is suited for residential and light commercial plumbing and HVAC applications where dissimilar tube sizes must be joined in a single inline connection. Typical installation scenarios include connecting copper or compatible tubing runs during system assembly or repair, particularly in tight spaces where soldered fittings are impractical. The reducer configuration accommodates a transition from 3/8 inch to 1/2 inch tubing in one fitting.

Key Features

• Reduces from 3/8 inch to 1/2 inch in a single inline compression union
• No soldering or brazing required for installation
• Re-serviceable connection allows disassembly and reassembly
• Compact union design for in-line tube joins with access from both ends

Compatibility

Designed as an OEM-style compression union for use with 3/8 inch and 1/2 inch outside-diameter tubing in residential and light commercial plumbing or HVAC systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes, including IPC guidelines for plumbing connections. Shut off and depressurize the supply line before disassembling or installing any compression fitting. Hand-tighten the compression nut before applying a wrench to avoid cross-threading, and do not overtighten, as this can damage the compression ferrule and compromise the seal. Inspect ferrules for deformation before reuse.
