Nibco B145650 Cast Copper Tee 3/8x3/8x1/4 C X C X F

Product Description

The NIBCO B145650 is a cast copper pressure tee fitting used to create a branch connection in copper piping systems. It features a sweat-by-sweat-by-female (C x C x F) end connection configuration, meaning two of the three ports accept soldered copper tube ends while the third port accepts a female threaded connection. Sized at 3/8 x 3/8 x 1/4 inches, this tee suits tight-space plumbing runs where a mixed solder-and-thread branch connection is needed. Licensed plumbers and HVAC technicians install this type of fitting in residential and light commercial water distribution and refrigerant piping systems. Cast copper construction meets ASTM B584 and ISO standards.

This fitting is appropriate for pressure applications in residential and light commercial plumbing and HVAC systems. The 3/8-inch run ports cover common supply or branch lines, while the 1/4-inch female threaded branch port allows connection to threaded fittings, valves, or instrumentation. Its compact size makes it well suited for confined mechanical spaces, equipment connections, and manifold assemblies where both sweat and threaded connections are required on the same fitting body.

Key Features

• Cast copper construction meets ASTM B584 and ISO standards for pressure fittings
• C x C x F end connections combine sweat and female threaded ports in one body
• 3/8 x 3/8 x 1/4 inch sizing suits common small-diameter branch configurations
• Pressure-rated fitting design for water distribution and compatible fluid systems
• Single-piece cast construction for consistent wall thickness and reliable soldering performance

Compatibility

Designed as an OEM-style pressure fitting for use in residential and light commercial copper piping systems where sweat and female threaded connections are required at a branch point.

Installation Notes

Installation should be performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off and depressurize the system completely before cutting into any existing line. The C x C ports require proper tube preparation, flux application, and soldering per accepted trade practice; the F port accepts a standard male-threaded fitting with appropriate thread sealant. Do not apply heat to an assembled threaded connection or to a fitting that has not been fully drained and dried.
