Dakota Sourcing 13219 Copper Cap 1/2 in Od 3/8 in Id

Product Description

The DAKOTA SOURCING 13219 is a copper cap fitting designed to seal the end of a copper tube or pipe. With an outside diameter of 1/2 inch and an inside diameter of 3/8 inch, this cap provides a secure, pressure-rated termination point for copper piping systems. Copper caps of this type are standard components in plumbing, HVAC refrigerant line, and hydronic heating applications. Licensed plumbers, HVAC technicians, and pipefitters install these fittings during new construction, system modifications, and service repairs where a line end must be permanently or temporarily closed.

This copper cap is suited for residential and light commercial plumbing and refrigeration systems where 1/2 inch OD copper tubing is present. Common applications include capping unused branch lines, sealing off decommissioned supply runs, and pressure-testing isolated sections of a piping circuit. The fitting is compatible with standard copper tube and is joined using conventional sweat-soldering techniques.

Key Features

• 1/2 inch OD and 3/8 inch ID dimensions for standard copper tube termination
• Copper construction provides corrosion resistance and reliable solder adhesion
• Suitable for sweat-solder installation using standard torch and flux methods
• Compact cap profile fits in tight spaces common in wall cavities and mechanical rooms

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1/2 inch OD copper tubing in residential and commercial plumbing and HVAC piping systems.

Installation Notes

Installation of copper caps should be performed by a licensed plumber or HVAC technician familiar with sweat-soldering practices. Shut off and depressurize the system and drain any standing water from the line before beginning work. Clean the tube end and the interior of the cap with emery cloth and apply appropriate flux before applying heat with a torch. Local plumbing codes, including applicable IPC requirements, govern the use of solder alloys and pressure ratings for the system being serviced.
