Brasscraft 62-6-4X Reducing Union Compression 3/8 X 1/4 Inch

Product Description

The BRASSCRAFT 62-6-4X is a reducing union compression fitting from the 62 Series line, designed to join two sections of tubing with different outside diameters in a single inline connection. It accepts 3/8-inch nominal tubing on one end and 1/4-inch nominal tubing on the other, making it well suited for transitions in supply lines where a size change is required. Constructed from brass, this fitting delivers reliable corrosion resistance and long service life in both water and gas-compatible plumbing applications. Plumbers and HVAC technicians install this type of fitting without soldering or brazing, using compression nuts and ferrules to create a leak-free mechanical seal.

The 62-6-4X is used in residential and light commercial plumbing and HVAC systems where two tubing sizes must be joined in line. Common applications include potable water supply lines, refrigeration tubing transitions, and fuel gas distribution lines where the nominal tubing size changes between components. The compression end style allows field installation with basic hand tools and does not require open flame, making it appropriate for retrofit and repair work in confined spaces or near existing fixtures.

Key Features

• Reduces from 3/8-inch to 1/4-inch nominal tubing in a single fitting
• Compression end style on both sides — no soldering or brazing required
• Brass construction provides corrosion resistance and durability
• Inline union design allows straight-run tubing transitions
• Suitable for water, refrigeration, and compatible gas line applications

Compatibility

Designed as an OEM-style compression reducing union compatible with standard 3/8-inch and 1/4-inch nominal copper or compatible soft tubing used in residential and light commercial plumbing and HVAC supply line applications.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off the water or gas supply and relieve line pressure completely before cutting or disconnecting any tubing. Ensure tubing ends are cut square and deburred before seating the ferrule and tightening the compression nut — overtightening can deform the ferrule and cause leaks. Consult local plumbing codes and the IPC or IFGC as applicable for approved fitting use in potable water or fuel gas systems.
