The MERIT BRASS SW3416D-06 is a 3/8-inch socket weld pipe end cap machined from 304 stainless steel. It is designed to permanently close the end of a pipe run in high-pressure process and utility piping systems. The cap accepts a pipe end into its socket and is joined by fillet welding, creating a leak-tight, full-penetration closure rated to 3,000 psi. Plumbers, pipefitters, and industrial maintenance technicians install this fitting wherever a clean, pressure-rated pipe termination is required in corrosive or sanitary environments.
This end cap is suited for use in residential and commercial plumbing, chemical process lines, food and beverage facilities, and industrial utility systems where 304 stainless steel provides adequate corrosion resistance. The socket weld configuration is common in small-bore high-pressure piping where threaded connections are undesirable and butt-weld access is limited. It is sold individually, making it practical for single-point repairs or small-batch fabrication projects.
Designed as an OEM-style socket weld end cap for 3/8-inch small-bore high-pressure piping systems fabricated from or compatible with 304 stainless steel fittings.
Installation should be performed by a qualified pipefitter or welder familiar with ASME B16.11 socket weld fitting standards. Depressurize and isolate the pipe system completely before fitting and welding. The pipe end must be cleaned and properly inserted to the correct socket depth before tack welding to ensure full fillet weld integrity. Follow applicable local mechanical codes and welding procedure specifications for stainless steel to avoid sensitization or contamination of the weld zone.
