Ndl Industries W7016 Copper Cap 3-1/8 Inches

Product Description

The NDL INDUSTRIES W7016 is a standard copper cap fitting sized at 3-1/8 inches, used to seal the open end of a copper pipe or tube. It provides a clean, pressure-rated termination point in refrigeration, HVAC, and plumbing applications. The cap is installed by soldering directly onto the pipe end, creating a leak-free closure. HVAC technicians and plumbers use this fitting when capping off a line during system modification, decommissioning, or staged installation work.

This copper cap is suited for residential and light commercial HVAC and refrigeration piping systems where a 3-1/8 inch connection size is required. It is commonly used when terminating suction or liquid lines, capping off manifold ports, or closing out branch lines during retrofit or new construction work. The fitting ships in a box quantity of 2, which is practical for jobs requiring a matched pair of capped terminations.

Key Features

• Standard cap configuration for straightforward end-of-line termination
• 3-1/8 inch fitting connection size for large-diameter copper tubing
• Copper construction provides corrosion resistance and solder compatibility
• Box quantity of 2 supports common paired-termination applications
• Compatible with standard sweat soldering installation methods

Compatibility

Designed as an OEM-style copper sweat cap for use with 3-1/8 inch outside-diameter copper tubing in HVAC, refrigeration, and plumbing piping systems.

Installation Notes

Installation is performed by a licensed HVAC technician or plumber using standard sweat soldering techniques. Recover any refrigerant and isolate the system before cutting or uncapping any refrigerant lines, in accordance with EPA Section 608 requirements. Clean the pipe end and fitting socket thoroughly before applying flux and solder to ensure a leak-free joint. Allow the joint to cool fully before restoring system pressure.
