Elkhart Products CAP-12 Copper Tube Cap 1/2 Inch

Product Description

The ELKHART PRODUCTS CAP-12 is a copper solder-type tube cap designed to close off the end of a 1/2-inch copper tube. Part of the KLEENFIT product line, this cap is cleaned and bagged from the factory to meet the cleanliness requirements of refrigeration and plumbing installations. It connects via soldering, creating a permanent, leak-tight seal on open tube ends during system repairs, modifications, or new construction. Licensed plumbers and HVAC technicians rely on this type of fitting when capping unused ports, isolating sections of a system, or completing stub-out work on copper piping.

This cap is suited for residential and light commercial plumbing and HVAC applications wherever a 1/2-inch copper tube end must be permanently sealed. Its KLEENFIT designation indicates the fitting has been cleaned and bagged to reduce flux contamination risk, making it appropriate for use in refrigerant lines, potable water systems, and hydronic piping where contamination control matters.
