With an outside diameter of 7\/8 inches and an inside diameter of 3\/4 inches, this cap fits standard 3\/4-inch copper tubing. It is soldered in place using standard copper brazing or soft-soldering technique. Plumbers, HVAC technicians, and refrigeration mechanics install this fitting when a pipe end must be sealed off permanently or temporarily during pressure testing or system modification.\u003c\/p\u003e\u003cp\u003eThis cap is suited for residential and light commercial applications where a clean, pressure-rated termination is required on a copper tube end. Common install scenarios include capping unused branch lines, isolating sections of a hydronic system, and sealing refrigerant line stubs during system repairs or additions. The 3\/4-inch nominal size is one of the most frequently encountered tube sizes in residential plumbing and HVAC work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-inch OD fits standard 3\/4-inch copper tubing\u003c\/li\u003e\n\u003cli\u003e3\/4-inch ID for consistent sweat-solder fit\u003c\/li\u003e\n\u003cli\u003eCopper construction for corrosion resistance and long service life\u003c\/li\u003e\n\u003cli\u003eCompatible with standard soft-solder and brazing procedures\u003c\/li\u003e\n\u003cli\u003eSuitable for plumbing, HVAC, and refrigeration piping terminations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sweat fitting for use with standard 3\/4-inch nominal copper tubing in plumbing, HVAC, and refrigeration piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or HVAC technician using standard copper sweat-soldering tools including a torch, flux, and appropriate solder or brazing alloy. Shut off and depressurize the system and purge any refrigerant or fluid before cutting or capping any line. All work must comply with applicable local plumbing codes and, where refrigerant lines are involved, EPA Section 608 requirements.
