The ANDERSON METALS CORP 738108-12 is a 3/4 inch rough brass pipe cap designed to terminate open pipe ends in plumbing systems. This fitting creates a secure, leak-resistant closure on threaded pipe, making it suitable for pressure testing, system shutoffs, and permanent end-of-line applications. Constructed from rough brass, it delivers solid corrosion resistance in both hot and cold water service. The 738108-12 meets the lead-free requirements of Public Law 111-380, making it compliant for use in potable water systems. Licensed plumbers and pipefitters are the primary installers of this fitting.
This pipe cap is used in residential and light commercial plumbing installations where a 3/4 inch threaded pipe end requires capping. Common applications include shutting off branch lines during system expansions, isolating unused outlets, and pressure-testing completed pipe runs. It is sold in a bulk pack of 5 units per package, making it practical for service contractors who regularly cap multiple lines on a single job.
Designed as an OEM-style replacement fitting compatible with standard 3/4 inch NPT threaded pipe in residential and commercial plumbing systems.
Installation of pipe caps is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before installing or removing any threaded fitting. Apply thread sealant tape or paste to the male threads before threading the cap on by hand, then tighten with a pipe wrench — do not overtighten, as this can crack brass fittings. Pressure-test the completed assembly before returning the system to service.
