Eaton 621X2 Compression Tube Union

Product Description

The EATON 621X2 is a compression tube union designed to join two compression-end tube lines in a single, leak-resistant connection. This fitting creates a straight union between two tube runs without the need for soldering or special tools, making it a practical choice for field repairs and new installations alike. Weighing 0.031 pounds, it is a compact, lightweight fitting suited for use in plumbing, refrigeration, and fluid-transfer systems where compression-style connections are specified. Licensed plumbers and HVAC technicians typically select this fitting for clean, reliable inline joins.

This compression tube union is appropriate for residential and light commercial applications where two tube ends must be joined inline using compression-style fittings. It is commonly installed in copper or compatible tubing systems during service calls or new construction where a solderless connection method is preferred or required. The dual compression-end configuration allows the technician to complete the join using standard hand tools without open flame.

Key Features

• Compression x compression end connections on both sides for a solderless inline join
• Straight union configuration simplifies inline tube repairs and extensions
• Lightweight construction at 0.031 pounds for easy handling in tight spaces
• No soldering or brazing required, reducing installation time and flame risk
• Single-piece unit quantity simplifies small-quantity procurement for service calls

Compatibility

Designed as an OEM-style replacement and general-use compression fitting for plumbing and fluid-transfer systems that utilize compression-end tube connections.

Installation Notes

Installation is typically performed by a licensed plumber or qualified HVAC technician. Shut off the fluid supply and relieve any line pressure before disassembling existing connections or installing this fitting. Ensure tube ends are cut cleanly and deburred before seating the compression ferrule to achieve a proper seal. Do not overtighten the compression nut, as this can deform the ferrule and cause leaks.
