Mueller Streamline CAP00285 Flush Cap 1/2 Inch Sweat

Product Description

The MUELLER STREAMLINE CAP00285 is a flush-style wrot copper end cap used to terminate 1/2-inch sweat (solder) connections in copper piping systems. Sized at 0.53 inches in length and 0.29 inches in both height and width, this cap weighs 0.188 pounds and is built to the dimensional and pressure standards expected in residential and commercial plumbing. Licensed plumbers install this fitting during rough-in, repairs, or system pressure testing when a copper run must be capped off cleanly and permanently. The wrot copper construction ensures consistent wall thickness and reliable soldering performance across a wide range of pipe and tubing applications.

This end cap is suited for use in potable water supply systems, hydronic heating lines, and general copper plumbing installations where a sweat-connect termination is required. Its flush cap design sits close to the pipe end, making it appropriate for tight-clearance installations. Compliance with NSF 61G confirms suitability for potable water contact. The 1/2-inch sweat connection is among the most common sizes in residential plumbing, making this cap a standard item for service and new construction work alike.

Installation Notes

Installation is performed by a licensed plumber using standard copper soldering tools including a torch, flux, and lead-free solder in accordance with local plumbing codes and IPC requirements. Shut off the water supply and fully drain the line before cutting or fitting the cap. Ensure the pipe end is clean, deburred, and properly fluxed before sweating the cap in place. Do not apply heat directly to the cap body for an extended period, as overheating can compromise the fitting.
