Mueller Streamline CAP00862 Wrot Copper Flush Cap

Product Description

The MUELLER STREAMLINE CAP00862 is a wrot copper flush cap designed to terminate 5/8-inch sweat (solder) connections in residential and commercial plumbing and HVAC piping systems. Manufactured from wrot copper, this cap delivers reliable, leak-resistant closure on open tube ends. At 0.75 inches outer diameter and weighing just 0.03 pounds, it is a compact, lightweight fitting suited for tight spaces. It meets a full range of ASME and NSF compliance standards, making it appropriate for potable water and refrigeration piping installations. Licensed plumbers and HVAC technicians are the primary installers for this type of fitting.

This cap is used wherever an open copper tube end must be permanently or temporarily sealed in a sweat-joined piping system. Typical applications include capping unused branch stubs, service ports, and rough-in lines in residential plumbing, hydronic heating, and refrigerant distribution systems. The flush cap style provides a low-profile termination that sits tight against the pipe end without added protrusion.
