Cerrobrass T2-5 Brass Flared Tube Union 5/16 in 45 Degree

Product Description

The CERROBRASS T2-5 is a brass flared tube union designed for joining 5/16-inch OD tubing in flared-connection systems. It features a 45-degree flare angle with three flare ends, allowing a standard inline union connection between two sections of tubing. Machined from brass, this fitting delivers reliable sealing in refrigeration, HVAC, and gas-line applications where flared connections are the required or code-specified joint type. Licensed technicians and experienced plumbers working with copper or compatible soft tubing will find this a straightforward, code-appropriate fitting for field repairs and new installations.

This union fitting is suited for residential and light commercial refrigeration and HVAC line sets, as well as fuel gas and LP distribution tubing where 45-degree flare fittings are permitted by the applicable code. The three-end flare-by-flare-by-flare configuration supports standard inline union applications. It is typically installed wherever a removable, leak-tight union joint is needed without soldering or brazing, making it a practical choice for service work on existing systems.

Key Features

• Brass construction for corrosion resistance and compatibility with refrigerant, LP, and natural gas service
• 45-degree flare angle matches standard SAE flare fittings used in HVAC and refrigeration tubing
• Flare x Flare x Flare end connections allow a full union joint with no soldering required
• 5/16-inch tube OD sizing fits common small-diameter copper and compatible soft tubing
• Compact and lightweight at 0.01 pounds, easy to carry in a service kit

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 5/16-inch OD tubing with 45-degree SAE flare connections, including residential HVAC, refrigeration, and applicable fuel gas tubing assemblies.

Installation Notes

Installation should be performed by a licensed HVAC technician, refrigeration mechanic, or plumber in accordance with applicable codes such as IFGC or local mechanical codes. Before installing, depressurize and recover any refrigerant or isolate the gas supply per safety requirements. Use a proper flaring tool calibrated for 45-degree SAE flares to prepare tubing ends, and hand-tighten the flare nuts before applying a final torque with an appropriate flare-nut wrench. Inspect flared seats for cracks or deformation before assembly to ensure a leak-free joint.
