Merit Brass SW3616D-04 Pipe End Cap 1/4 in 316 Ss 3000 Psi

Product Description

The MERIT BRASS SW3616D-04 is a 1/4 inch threaded pipe end cap machined from 316 stainless steel and rated to 3,000 psi. It terminates an open pipe end using a socket weld connection on both faces, creating a pressure-tight seal in high-demand fluid or gas systems. The 316 stainless steel construction resists corrosion in aggressive media including chlorides, acids, and marine environments. Plumbers, pipefitters, and industrial maintenance technicians install this fitting in process piping, chemical lines, and utility systems where a reliable, permanent end termination is required.

This end cap is suited for residential and commercial plumbing, as well as light industrial process piping applications. The socket weld configuration makes it appropriate for small-bore piping systems where leak integrity is critical. Typical install scenarios include capping unused branch outlets, blanking test ports, and terminating lines during system modifications or shutdowns. The 3,000 psi pressure rating supports use in moderate- to high-pressure service conditions.

Key Features

• 3,000 psi pressure rating suitable for moderate- to high-pressure service
• Socket weld end connection on both faces for secure, permanent pipe termination
• Threaded fitting type for installation flexibility
• 1/4 inch fitting size for small-bore piping applications
• Compact form factor — weighs 0.06 pounds

Compatibility

Designed as an OEM-style replacement or new-installation end cap for 1/4 inch socket weld piping systems constructed of 316 stainless steel in plumbing, process, and industrial applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable codes including IPC and ASME B31.3 for process piping. Depressurize and isolate the line completely before cutting or fitting any end cap. Socket weld fittings require proper fit-up and full-penetration welds per applicable welding procedures — do not tighten or force-fit to compensate for out-of-tolerance pipe ends. Inspect the completed weld and joint for leaks before returning the system to service.
